사용자가 Swift로 이미지를 선택하도록 허용하는 방법은 무엇입니까?
Swift로 첫 번째 iOS 애플리케이션 (iPhone 전용)을 작성하고 있습니다. 메인 애플리케이션보기에서는 사용자가 사진 갤러리에서 이미지를 선택할 수 있어야합니다.
ViewController.swift 의 다음 샘플 코드를 찾았습니다 .
class ViewController: UIImagePickerController, UINavigationControllerDelegate, UIImagePickerControllerDelegate {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) {
var imagePickerController = UIImagePickerController()
imagePickerController.delegate = self
imagePickerController.sourceType = UIImagePickerControllerSourceType.SavedPhotosAlbum
imagePickerController.allowsEditing = true
self.presentViewController(imagePickerController, animated: true, completion: { imageP in
})
}
func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image: UIImage!, editingInfo: NSDictionary!) {
let selectedImage : UIImage = image
println(selectedImage)
}
}

하지만 앱을 시작하면 검은 색 화면 만 표시됩니다. 내가 뭘 잘못하고 있니? 내가 찾은 또 다른 샘플 코드 는 Objective-C에 있는데 도움이되지 않습니다.
사용자가 UIImagePickerController로 이미지를 선택하게하려면 다음 코드를 사용하십시오.
import UIKit
class ViewController: UIViewController, UINavigationControllerDelegate, UIImagePickerControllerDelegate {
@IBOutlet var imageView: UIImageView!
@IBOutlet var chooseBuuton: UIButton!
var imagePicker = UIImagePickerController()
@IBAction func btnClicked() {
if UIImagePickerController.isSourceTypeAvailable(.savedPhotosAlbum){
print("Button capture")
imagePicker.delegate = self
imagePicker.sourceType = .savedPhotosAlbum
imagePicker.allowsEditing = false
present(imagePicker, animated: true, completion: nil)
}
}
func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image: UIImage!, editingInfo: NSDictionary!){
self.dismiss(animated: true, completion: { () -> Void in
})
imageView.image = image
}
}
@ user3182143 답변을 기반으로 신속한 4에 대한 완전한 복사-붙여 넣기 작업 이미지 선택기 :
import Foundation
import UIKit
class ImagePickerManager: NSObject, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
var picker = UIImagePickerController();
var alert = UIAlertController(title: "Choose Image", message: nil, preferredStyle: .actionSheet)
var viewController: UIViewController?
var pickImageCallback : ((UIImage) -> ())?;
override init(){
super.init()
}
func pickImage(_ viewController: UIViewController, _ callback: @escaping ((UIImage) -> ())) {
pickImageCallback = callback;
self.viewController = viewController;
let cameraAction = UIAlertAction(title: "Camera", style: .default){
UIAlertAction in
self.openCamera()
}
let galleryAction = UIAlertAction(title: "Gallery", style: .default){
UIAlertAction in
self.openGallery()
}
let cancelAction = UIAlertAction(title: "Cancel", style: .cancel){
UIAlertAction in
}
// Add the actions
picker.delegate = self
alert.addAction(cameraAction)
alert.addAction(galleryAction)
alert.addAction(cancelAction)
alert.popoverPresentationController?.sourceView = self.viewController!.view
viewController.present(alert, animated: true, completion: nil)
}
func openCamera(){
alert.dismiss(animated: true, completion: nil)
if(UIImagePickerController .isSourceTypeAvailable(.camera)){
picker.sourceType = .camera
self.viewController!.present(picker, animated: true, completion: nil)
} else {
let alertWarning = UIAlertView(title:"Warning", message: "You don't have camera", delegate:nil, cancelButtonTitle:"OK", otherButtonTitles:"")
alertWarning.show()
}
}
func openGallery(){
alert.dismiss(animated: true, completion: nil)
picker.sourceType = .photoLibrary
self.viewController!.present(picker, animated: true, completion: nil)
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
picker.dismiss(animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
picker.dismiss(animated: true, completion: nil)
let image = info[UIImagePickerControllerOriginalImage] as! UIImage
pickImageCallback?(image)
}
// // For Swift 4.2
// func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
// picker.dismiss(animated: true, completion: nil)
// guard let image = info[.originalImage] as? UIImage else {
// fatalError("Expected a dictionary containing an image, but was provided the following: \(info)")
// }
// pickImageCallback?(image)
// }
@objc func imagePickerController(_ picker: UIImagePickerController, pickedImage: UIImage?) {
}
}
다음과 같이 viewcontroller에서 호출하십시오.
ImagePickerManager().pickImage(self){ image in
//here is the image
}
또한 다음 키를 포함하는 것을 잊지 마십시오 info.plist.
<key>NSCameraUsageDescription</key>
<string>This app requires access to the camera.</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>This app requires access to the photo library.</string>
Swift 3의 경우
1- 먼저 info.plist에 다음 키를 추가해야합니다.
<key>NSPhotoLibraryUsageDescription</key>
<string>This app requires access to the photo library.</string>
2- 뷰 컨트롤러는 UIImagePickerControllerDelegate, UINavigationControllerDelegate 프로토콜을 준수해야합니다.
class ImagePickerViewController: UIViewController,UIImagePickerControllerDelegate, UINavigationControllerDelegate {}
3- 반환 / 선택된 이미지를 바인딩하는 데 사용할 UIImage를 선언해야합니다.
@IBOutlet weak var myImageView: UIImageView!
@IBoutlet weak var upLoadImageBtn:UIImage!
let imagePicker = UIImagePickerController()
4- pickerImage Delegate를 ViewController로 설정하십시오.
imagePicker.delegate = self
5- 업로드 버튼의 경우 작업을 실행하고 이미지 선택기를 표시하려면 다음 이미지를 좋아해야합니다.
@IBAction func upLoadImageBtnPressed(_ sender: AnyObject) {
imagePicker.allowsEditing = false
imagePicker.sourceType = .photoLibrary
/*
The sourceType property wants a value of the enum named UIImagePickerControllerSourceType, which gives 3 options:
UIImagePickerControllerSourceType.PhotoLibrary
UIImagePickerControllerSourceType.Camera
UIImagePickerControllerSourceType.SavedPhotosAlbum
*/
present(imagePicker, animated: true, completion: nil)
}
6- View Controller는 이미지 선택기 델리게이트에 대한 델리게이트 메서드를 구현해야합니다.
// MARK: - ImagePicker Delegate
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
myImageView.contentMode = .scaleAspectFit
myImageView.image = pickedImage
}
/*
Swift Dictionary named “info”.
We have to unpack it from there with a key asking for what media information we want.
We just want the image, so that is what we ask for. For reference, the available options are:
UIImagePickerControllerMediaType
UIImagePickerControllerOriginalImage
UIImagePickerControllerEditedImage
UIImagePickerControllerCropRect
UIImagePickerControllerMediaURL
UIImagePickerControllerReferenceURL
UIImagePickerControllerMediaMetadata
*/
dismiss(animated: true, completion: nil)
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
dismiss(animated: true, completion:nil)
}

사진 라이브러리 이미지를 신속하게 코딩하려면 다음을 수행하십시오.
var pkcrviewUI = UIImagePickerController()
if UIImagePickerController .isSourceTypeAvailable(UIImagePickerControllerSourceType.PhotoLibrary)
{
pkcrviewUI.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
pkcrviewUI.allowsEditing = true
pkcrviewUI.delegate = self
[self .presentViewController(pkcrviewUI, animated: true , completion: nil)]
}
이 질문이 1 년 전이라는 것을 알고 있지만 여기 저에게 잘 작동하는 꽤 간단한 코드 (대부분 이 튜토리얼의 코드 )가 있습니다.
import UIKit
class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
@IBOutlet weak var imageView: UIImageView!
var imagePicker = UIImagePickerController()
override func viewDidLoad() {
super.viewDidLoad()
self.imagePicker.delegate = self
}
@IBAction func loadImageButtonTapped(sender: AnyObject) {
print("hey!")
self.imagePicker.allowsEditing = false
self.imagePicker.sourceType = .SavedPhotosAlbum
self.presentViewController(imagePicker, animated: true, completion: nil)
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
self.imageView.contentMode = .ScaleAspectFit
self.imageView.image = pickedImage
}
dismissViewControllerAnimated(true, completion: nil)
}
func imagePickerControllerDidCancel(picker: UIImagePickerController) {
self.imagePicker = UIImagePickerController()
dismissViewControllerAnimated(true, completion: nil)
}
물론 위의 답변은 주요 문제를 해결합니다.
Info.plist에 다음 플래그가 없기 때문에 사진 앨범을 시작하는 동안 Swift 3.0에서 충돌이 발생했습니다.
개인 정보-사진 라이브러리 사용 설명-> NSPhotoLibraryUsageDescription
개인 정보-카메라 사용 설명-> NSCameraUsageDescription
[![스크린 샷 [1]](https://i.stack.imgur.com/CmxrH.png)
비슷한 문제가 발생하면 추가하십시오.
감사 !
For Swift 4
이 코드는 나를 위해 작동합니다!
import UIKit
class ViewController: UIViewController, UINavigationControllerDelegate, UIImagePickerControllerDelegate {
@IBOutlet var imageView: UIImageView!
@IBOutlet var chooseBuuton: UIButton!
var imagePicker = UIImagePickerController()
override func viewDidLoad() {
super.viewDidLoad()
imagePicker.delegate = self
}
@IBAction func btnClicked() {
if UIImagePickerController.isSourceTypeAvailable(.savedPhotosAlbum)
{
print("Button capture")
imagePicker.sourceType = .savedPhotosAlbum;
imagePicker.allowsEditing = false
self.present(imagePicker, animated: true, completion: nil)
}
}
@objc func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
let chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage
imageView.image = chosenImage
dismiss(animated: true, completion: nil)
}
}
다음은이를 수행하는 쉬운 방법입니다.
하지만 먼저 info.plist에 (Privacy-Photo Library Usage Description)을 추가해야하며 viewController에 버튼과 UIImageView가 있어야합니다.
그런 다음 UIImageView의 콘센트 (이 코드에서 콘센트는 myImage라고 함)와 버튼의 동작 (내 코드에서 가져 오기 작업을 호출했습니다)을 만듭니다.
import UIKit
class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
override func viewDidLoad() {
super.viewDidLoad()
}
@IBOutlet weak var myImage: UIImageView!
@IBAction func importing(_ sender: Any) {
let Picker = UIImagePickerController()
Picker.delegate = self
Picker.sourceType = .photoLibrary
self.present(Picker, animated: true, completion: nil)
Picker.allowsEditing = true
Picker.mediaTypes = UIImagePickerController.availableMediaTypes(for: .photoLibrary)!
}
func imagePickerController(_ picker: UIImagePickerController,didFinishPickingMediaWithInfo info: [String : Any])
{
let chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage //1
myImage.contentMode = .scaleAspectFit //2
myImage.image = chosenImage //3
dismiss(animated:true, completion: nil) //4
}
}
별도의 버튼을 원하지 않는 경우 다른 방법이 있습니다. imageView 자체에 제스처를 추가했습니다. 이미지를 탭하면 두 가지 옵션이있는 경고가 표시됩니다. 갤러리 / 사진 라이브러리에서 선택하거나 알림을 취소 할 수있는 옵션이 있습니다.
import UIKit
import CoreData
class AddDetailsViewController: UIViewController, UITextFieldDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
@IBOutlet weak var imageView: UIImageView!
var picker:UIImagePickerController? = UIImagePickerController()
@IBAction func saveButton(sender: AnyObject) {
let managedContext = (UIApplication.sharedApplication().delegate as? AppDelegate)!.managedObjectContext
let entity = NSEntityDescription.entityForName("Person", inManagedObjectContext: managedContext)
let person = Person(entity: entity!, insertIntoManagedObjectContext: managedContext)
person.image = UIImageJPEGRepresentation(imageView.image!, 1.0) //imageView.image
do {
try person.managedObjectContext?.save()
//people.append(person)
} catch let error as NSError {
print("Could not save \(error)")
}
}
override func viewDidLoad() {
super.viewDidLoad()
let tapGesture = UITapGestureRecognizer(target: self, action: #selector(AddDetailsViewController.tapGesture(_:)))
imageView.addGestureRecognizer(tapGesture)
imageView.userInteractionEnabled = true
picker?.delegate = self
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func tapGesture(gesture: UIGestureRecognizer) {
let alert:UIAlertController = UIAlertController(title: "Profile Picture Options", message: nil, preferredStyle: UIAlertControllerStyle.ActionSheet)
let gallaryAction = UIAlertAction(title: "Open Gallary", style: UIAlertActionStyle.Default) {
UIAlertAction in self.openGallary()
}
let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel) {
UIAlertAction in self.cancel()
}
alert.addAction(gallaryAction)
alert.addAction(cancelAction)
self.presentViewController(alert, animated: true, completion: nil)
}
func openGallary() {
picker!.allowsEditing = false
picker!.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
presentViewController(picker!, animated: true, completion: nil)
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
imageView.contentMode = .ScaleAspectFit
imageView.image = pickedImage
}
dismissViewControllerAnimated(true, completion: nil)
}
func cancel(){
print("Cancel Clicked")
}
}
질문에 더 많은 것을 추가하여 CoreData에 이미지를 저장하는 로직을 구현했습니다.
버튼을 클릭하고 이미지 갤러리를 열고 imageview swift 3.0에서 이미지를 설정하십시오.
세 위임 UIImagePickerControllerDelegate, UIPopoverControllerDelegate, UINavigationControllerDelegate 추가
var picker:UIImagePickerController?=UIImagePickerController()
@IBOutlet var imgPhoto: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
picker?.delegate=self
}
@IBAction func btnAddPhotoClicked(_ sender: UIButton) {
openGallary()
}
func openGallary()
{
picker!.allowsEditing = false
picker!.sourceType = UIImagePickerControllerSourceType.photoLibrary
present(picker!, animated: true, completion: nil)
}
//MARK:- ImagePicker Controller Delegate
//MARK:-
func imagePickerControllerDidCancel(_ picker:
UIImagePickerController) {
dismiss(animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let chosenImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
imgPhoto.contentMode = .scaleToFill
imgPhoto.image = chosenImage
} else{
print("Something went wrong")
}
self.dismiss(animated: true, completion: nil)
}
여기서 언급하기 만하면됩니다 : info[UIImagePickerControllerEditedImage]대부분의 경우에 사용하고 싶은 것입니다.
그 외에 여기에 대한 답변은 포괄적입니다.
UIImagePickerControllerDelegate를 사용하여 이미지를 그리는 것은 쉽습니다.
@objc func masterAction(_ sender: UIButton)
{
if UIImagePickerController.isSourceTypeAvailable(.savedPhotosAlbum){
print("Button capture")
imagePicker.delegate = self
imagePicker.sourceType = .savedPhotosAlbum;
imagePicker.allowsEditing = false
self.present(imagePicker, animated: true, completion: nil)
}
print("hello i'm touch \(sender.tag)")
}
func imagePickerControllerDidCancel(_ picker:
UIImagePickerController) {
dismiss(animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let chosenImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
print("Get Image \(chosenImage)")
ImageList.insert(chosenImage, at: 0)
ArrayList.insert("", at: 0)
Collection_Vw.reloadData()
} else{
print("Something went wrong")
}
self.dismiss(animated: true, completion: nil)
}
일반 이미지 만 선택하려면 아래 코드에서 사용할 수 있습니다. 선택한 이미지가 파노라마 이미지가 아닌지 확인하세요.
let picker = UIImagePickerController()
func photoFromLibrary() {
self.picker.allowsEditing = true
self.picker.sourceType = .photoLibrary
//picker.mediaTypes = UIImagePickerController.availableMediaTypes(for: .photoLibrary)!
self.present(self.picker, animated: true, completion: nil)
}
func shootPhoto() {
if UIImagePickerController.isSourceTypeAvailable(.camera) {
self.picker.allowsEditing = true
self.picker.sourceType = UIImagePickerControllerSourceType.camera
self.picker.cameraCaptureMode = .photo
self.picker.modalPresentationStyle = .fullScreen
self.present(self.picker,animated: true,completion: nil)
}
}
//Image picker delegate
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
let str = "\(info["UIImagePickerControllerOriginalImage"]!)"
let s = str.slice(from: "{", to: "}")
if let arr = s?.components(separatedBy: ","){
if arr.count >= 2 {
if Int(arr[0])! > 11000 {
picker.dismiss(animated:true, completion: nil)
self.makeToast("Invalid Image!!!")
return
}
}
}
}
if let image = info[UIImagePickerControllerOriginalImage] as? UIImage{
self.UserImageView.image = image
}
picker.dismiss(animated:true, completion: nil)
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController)
{
picker.dismiss(animated: true, completion: nil)
}
Xcode 10, Swift 4.2
아래는 약간 최적화 된 구현 버전입니다. 이것은 Swift 4.2에 있으며 나도 테스트했습니다.
여기에서 ViewController의 전체 코드를 볼 수 있습니다. IBOutlet (imageView) 및 IBAction (didTapOnChooseImageButton)도 정의하고 스토리 보드에 연결해야합니다. 도움이 되었기를 바랍니다.
import UIKit
class ImagePickViewController: UIViewController,UIImagePickerControllerDelegate,UINavigationControllerDelegate {
var imagePicker = UIImagePickerController()
@IBOutlet weak var imageView: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
@IBAction func didTapOnChooseImageButton(_ sender: Any) {
let alert:UIAlertController=UIAlertController(title: "Choose Image", message: nil, preferredStyle: UIAlertController.Style.actionSheet)
let cameraAction = UIAlertAction(title: "Camera", style: UIAlertAction.Style.default) {
UIAlertAction in
self.openCamera(UIImagePickerController.SourceType.camera)
}
let gallaryAction = UIAlertAction(title: "Gallary", style: UIAlertAction.Style.default) {
UIAlertAction in
self.openCamera(UIImagePickerController.SourceType.photoLibrary)
}
let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertAction.Style.cancel) {
UIAlertAction in
}
// Add the actions
imagePicker.delegate = self as UIImagePickerControllerDelegate & UINavigationControllerDelegate
alert.addAction(cameraAction)
alert.addAction(gallaryAction)
alert.addAction(cancelAction)
self.present(alert, animated: true, completion: nil)
}
func openCamera(_ sourceType: UIImagePickerController.SourceType) {
imagePicker.sourceType = sourceType
self.present(imagePicker, animated: true, completion: nil)
}
//MARK:UIImagePickerControllerDelegate
func imagePickerController(_ picker: UIImagePickerController,
didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
imageView.image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage
imagePicker.dismiss(animated: true, completion: nil)
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
print("imagePickerController cancel")
}
}
Swift 3.4.1의 경우 다음 코드가 작동합니다.
implements
class AddAdvertisementViewController : UINavigationControllerDelegate, UIImagePickerControllerDelegate, UIActionSheetDelegate
var imagePicker = UIImagePickerController()
var file :UIImage!
//action sheet tap on image
func tapOnButton(){
let optionMenu = UIAlertController(title: nil, message: "Add Photo", preferredStyle: .actionSheet)
let galleryAction = UIAlertAction(title: "Gallery", style: .default, handler:{
(alert: UIAlertAction!) -> Void in
self.addImageOnTapped()
})
let cameraAction = UIAlertAction(title: "Camera", style: .default, handler:{
(alert: UIAlertAction!) -> Void in
self.openCameraButton()
})
let cancleAction = UIAlertAction(title: "Cancel", style: .cancel, handler:{
(alert: UIAlertAction!) -> Void in
print("Cancel")
})
optionMenu.addAction(galleryAction)
optionMenu.addAction(cameraAction)
optionMenu.addAction(cancleAction)
self.present(optionMenu, animated: true, completion: nil)
}
func openCameraButton(){
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.camera)
{
imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = UIImagePickerControllerSourceType.camera;
imagePicker.allowsEditing = true
self.present(imagePicker, animated: true, completion: nil)
}
}
func addImageOnTapped(){
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.photoLibrary){
imagePicker.delegate = self
imagePicker.sourceType = UIImagePickerControllerSourceType.photoLibrary;
imagePicker.allowsEditing = true
self.present(imagePicker, animated: true, completion: nil)
}
}
//picker pick image and store value imageview
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]){
if let image = info[UIImagePickerControllerOriginalImage] as? UIImage
{
file = image
imgViewOne.image = image
imagePicker.dismiss(animated: true, completion: nil);
}
}
