Objective-C (iOS)에서 이미지에 텍스트를 쓰는 방법은 무엇입니까?
프로그래밍 방식으로 이와 같은 이미지를 만들고 싶습니다.
저와 함께 상단 이미지와 텍스트가 있습니다. 이미지에 텍스트를 써야하나요?
완전한 .png 이미지 (이미지 + 라벨)로 만들고 버튼의 배경으로 설정하고 싶습니다.
이미지 내부에 텍스트를 그리고 결과 이미지를 반환합니다.
+(UIImage*) drawText:(NSString*) text
inImage:(UIImage*) image
atPoint:(CGPoint) point
{
UIFont *font = [UIFont boldSystemFontOfSize:12];
UIGraphicsBeginImageContext(image.size);
[image drawInRect:CGRectMake(0,0,image.size.width,image.size.height)];
CGRect rect = CGRectMake(point.x, point.y, image.size.width, image.size.height);
[[UIColor whiteColor] set];
[text drawInRect:CGRectIntegral(rect) withFont:font];
UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return newImage;
}
용법:
// note: replace "ImageUtils" with the class where you pasted the method above
UIImage *img = [ImageUtils drawText:@"Some text"
inImage:img
atPoint:CGPointMake(0, 0)];
이미지 안의 텍스트 원점을 0,0에서 원하는 지점으로 변경하십시오.
텍스트 뒤에 단색 사각형을 그리려면 줄 앞에 다음을 추가합니다 [[UIColor whiteColor] set];
.
[[UIColor brownColor] set];
CGContextFillRect(UIGraphicsGetCurrentContext(),
CGRectMake(0, (image.size.height-[text sizeWithFont:font].height),
image.size.width, image.size.height));
단색 사각형의 원점을 계산하기 위해 텍스트 크기를 사용하고 있지만 원하는 숫자로 바꿀 수 있습니다.
iOS 7 지원에 대한 첫 번째 답변에 대한 나의 기여 :
+(UIImage*) drawText:(NSString*) text
inImage:(UIImage*) image
atPoint:(CGPoint) point
{
UIGraphicsBeginImageContextWithOptions(image.size, YES, 0.0f);
[image drawInRect:CGRectMake(0,0,image.size.width,image.size.height)];
CGRect rect = CGRectMake(point.x, point.y, image.size.width, image.size.height);
[[UIColor whiteColor] set];
UIFont *font = [UIFont boldSystemFontOfSize:12];
if([text respondsToSelector:@selector(drawInRect:withAttributes:)])
{
//iOS 7
NSDictionary *att = @{NSFontAttributeName:font};
[text drawInRect:rect withAttributes:att];
}
else
{
//legacy support
[text drawInRect:CGRectIntegral(rect) withFont:font];
}
UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return newImage;
}
도움이 되었기를 바랍니다

다음은 Swift 버전입니다.
func textToImage(drawText: NSString, inImage: UIImage, atPoint:CGPoint)->UIImage{
// Setup the font specific variables
var textColor: UIColor = UIColor.whiteColor()
var textFont: UIFont = UIFont(name: "Helvetica Bold", size: 12)!
//Setup the image context using the passed image.
UIGraphicsBeginImageContext(inImage.size)
//Setups up the font attributes that will be later used to dictate how the text should be drawn
let textFontAttributes = [
NSFontAttributeName: textFont,
NSForegroundColorAttributeName: textColor,
]
//Put the image into a rectangle as large as the original image.
inImage.drawInRect(CGRectMake(0, 0, inImage.size.width, inImage.size.height))
// Creating a point within the space that is as bit as the image.
var rect: CGRect = CGRectMake(atPoint.x, atPoint.y, inImage.size.width, inImage.size.height)
//Now Draw the text into an image.
drawText.drawInRect(rect, withAttributes: textFontAttributes)
// Create a new image out of the images we have created
var newImage: UIImage = UIGraphicsGetImageFromCurrentImageContext()
// End the context now that we have the image we need
UIGraphicsEndImageContext()
//And pass it back up to the caller.
return newImage
}
그것을 호출하려면 이미지를 전달하십시오.

원래의 목표는지도의 특정 위치에 가격을 책정하는 것과 같이 AnnotaionView에서 사용할 수있는 동적 이미지를 만드는 것이었고 이로 인해 잘 작동했습니다. 이것이 같은 일을하려는 사람에게 도움이되기를 바랍니다.

이런 짓을 했어! 몇 가지 예를 찾아보고 결합한 후.
텍스트를 이미지 중앙에 배치하고 필요한 경우 글꼴 크기를 조정합니다.
UIImage *myImage = [UIImage imageNamed:@"promoicon.png"];
UIGraphicsBeginImageContext(myImage.size);
[myImage drawInRect:CGRectMake(0,0,myImage.size.width,myImage.size.height)];

Swift에서 워터 마크를 그리기 위해 UIImage에 대한 완전히 사용자 정의 된 확장을 만들었습니다.
extension UIImage{
enum WaterMarkCorner{
case TopLeft
case TopRight
case BottomLeft
case BottomRight
}
func waterMarkedImage(#waterMarkText:String, corner:WaterMarkCorner = .BottomRight, margin:CGPoint = CGPoint(x: 20, y: 20), waterMarkTextColor:UIColor = UIColor.whiteColor(), waterMarkTextFont:UIFont = UIFont.systemFontOfSize(20), backgroundColor:UIColor = UIColor.clearColor()) -> UIImage{
let textAttributes = [NSForegroundColorAttributeName:waterMarkTextColor, NSFontAttributeName:waterMarkTextFont]
let textSize = NSString(string: waterMarkText).sizeWithAttributes(textAttributes)
var textFrame = CGRectMake(0, 0, textSize.width, textSize.height)
let imageSize = self.size
switch corner{
case .TopLeft:
textFrame.origin = margin
case .TopRight:
textFrame.origin = CGPoint(x: imageSize.width - textSize.width - margin.x, y: margin.y)
case .BottomLeft:
textFrame.origin = CGPoint(x: margin.x, y: imageSize.height - textSize.height - margin.y)
case .BottomRight:
textFrame.origin = CGPoint(x: imageSize.width - textSize.width - margin.x, y: imageSize.height - textSize.height - margin.y)
}
/// Start creating the image with water mark
UIGraphicsBeginImageContext(imageSize)
self.drawInRect(CGRectMake(0, 0, imageSize.width, imageSize.height))
NSString(string: waterMarkText).drawInRect(textFrame, withAttributes: textAttributes)
let waterMarkedImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return waterMarkedImage
}
}
보시다시피 속성에 대한 몇 가지 기본값을 추가 했으므로 변경할 필요가없는 경우 무시할 수 있습니다. 사용 방법에 대한 몇 가지 예는 다음과 같습니다.
let watermark1 = image.waterMarkedImage(waterMarkText: "@yourapp")
let watermark2 = image.waterMarkedImage(waterMarkText: "your app name", corner: .TopRight, margin: CGPoint(x: 5, y: 5), waterMarkTextColor: UIColor.greenColor())
let watermark3 = image.waterMarkedImage(waterMarkText: "appName", waterMarkTextColor: UIColor.blackColor(), waterMarkTextFont: UIFont(name: "Helvatica", size: 25)!)
Swift 4.0 버전 :
extension UIImage
{
enum WaterMarkCorner
{
case TopLeft
case TopRight
case BottomLeft
case BottomRight
}
func waterMarkedImage(text:String, corner:WaterMarkCorner = .BottomRight, margin:CGPoint = CGPoint(x: 20, y: 20), color:UIColor = UIColor.white, font:UIFont = UIFont.systemFont(ofSize: 20), background:UIColor = UIColor.clear) -> UIImage?
{
let attributes = [NSAttributedStringKey.foregroundColor: color, NSAttributedStringKey.font:font]
let textSize = NSString(string: text).size(withAttributes: attributes)
var frame = CGRect(x: 0, y: 0, width: textSize.width, height: textSize.height)
let imageSize = self.size
switch corner
{
case .TopLeft:
frame.origin = margin
case .TopRight:
frame.origin = CGPoint(x: imageSize.width - textSize.width - margin.x, y: margin.y)
case .BottomLeft:
frame.origin = CGPoint(x: margin.x, y: imageSize.height - textSize.height - margin.y)
case .BottomRight:
frame.origin = CGPoint(x: imageSize.width - textSize.width - margin.x, y: imageSize.height - textSize.height - margin.y)
}
// Start creating the image with water mark
UIGraphicsBeginImageContext(imageSize)
self.draw(in: CGRect(x: 0, y: 0, width: imageSize.width, height: imageSize.height))
NSString(string: text).draw(in: frame, withAttributes: attributes)
let image = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return image
}
}
다음은 이미지의 텍스트를 올바르게 중앙에 배치하는 Swift 버전입니다. 이것은 다양한 크기의 텍스트에서 작동합니다.
func addTextToImage(text: NSString, inImage: UIImage, atPoint:CGPoint) -> UIImage{
// Setup the font specific variables
let textColor = YOURCOLOR
let textFont = YOUR SIZE
//Setups up the font attributes that will be later used to dictate how the text should be drawn
let textFontAttributes = [
NSFontAttributeName: textFont,
NSForegroundColorAttributeName: textColor,
]
// Create bitmap based graphics context
UIGraphicsBeginImageContextWithOptions(inImage.size, false, 0.0)
//Put the image into a rectangle as large as the original image.
inImage.drawInRect(CGRectMake(0, 0, inImage.size.width, inImage.size.height))
// Our drawing bounds
let drawingBounds = CGRectMake(0.0, 0.0, inImage.size.width, inImage.size.height)
let textSize = text.sizeWithAttributes([NSFontAttributeName:textFont])
let textRect = CGRectMake(drawingBounds.size.width/2 - textSize.width/2, drawingBounds.size.height/2 - textSize.height/2,
textSize.width, textSize.height)
text.drawInRect(textRect, withAttributes: textFontAttributes)
// Get the image from the graphics context
let newImag = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return newImag
}
이 방법을 사용하여 선택한 글꼴 및 색상 및 크기로 이미지에 텍스트 필드를 추가하십시오.
//Method to add
- (UIImage *) addText:(UIImage *)img text:(NSString *)text
{
CGRect rect = CGRectMake(0,0, img.size.width, img.size.height);
