UIView의 위치를 ​​변경하는 간단한 방법?


뷰의 크기를 변경하지 않고 다음 코드로 UIView의 위치를 ​​변경합니다.

CGRect f = aView.frame;
f.origin.x = 100; // new x
f.origin.y = 200; // new y
aView.frame = f;

보기 위치 만 변경하는 더 간단한 방법이 있습니까?


aView.center = CGPointMake(150, 150); // set center

또는

aView.frame = CGRectMake( 100, 200, aView.frame.size.width, aView.frame.size.height ); // set new position exactly

또는

aView.frame = CGRectOffset( aView.frame, 10, 10 ); // offset by an amount

편집하다:

아직 컴파일하지 않았지만 작동합니다.

#define CGRectSetPos( r, x, y ) CGRectMake( x, y, r.size.width, r.size.height )

aView.frame = CGRectSetPos( aView.frame, 100, 200 );

나는 같은 문제가 있었다. 이를 수정하는 간단한 UIView 카테고리를 만들었습니다.

.h

#import <UIKit/UIKit.h>


@interface UIView (GCLibrary)

@property (nonatomic, assign) CGFloat height;
@property (nonatomic, assign) CGFloat width;
@property (nonatomic, assign) CGFloat x;
@property (nonatomic, assign) CGFloat y;

@end

.미디엄

#import "UIView+GCLibrary.h"


@implementation UIView (GCLibrary)

- (CGFloat) height {
    return self.frame.size.height;
}

- (CGFloat) width {
    return self.frame.size.width;
}

- (CGFloat) x {
    return self.frame.origin.x;
}

- (CGFloat) y {
    return self.frame.origin.y;
}

- (CGFloat) centerY {
    return self.center.y;
}

- (CGFloat) centerX {
    return self.center.x;
}

- (void) setHeight:(CGFloat) newHeight {
    CGRect frame = self.frame;
    frame.size.height = newHeight;
    self.frame = frame;
}

- (void) setWidth:(CGFloat) newWidth {
    CGRect frame = self.frame;
    frame.size.width = newWidth;
    self.frame = frame;
}

- (void) setX:(CGFloat) newX {
    CGRect frame = self.frame;
    frame.origin.x = newX;
    self.frame = frame;
}

- (void) setY:(CGFloat) newY {
    CGRect frame = self.frame;
    frame.origin.y = newY;
    self.frame = frame;
}

@end

UIView에도 center속성이 있습니다. 크기를 조정하는 대신 위치를 이동하려면 변경하면됩니다. 예 :

aView.center = CGPointMake(50, 200);

그렇지 않으면 게시 한 방식대로 할 것입니다.


나는 여기에서 나를 크게 도왔던 gcamp의 답변과 유사한 접근 방식 (카테고리 사용)을 발견 했습니다 . 귀하의 경우는 다음과 같이 간단합니다.

aView.topLeft = CGPointMake(100, 200);

그러나 예를 들어 수평 중앙에 다른 뷰를 사용하여 왼쪽에 배치하려면 다음과 같이하면됩니다.

aView.topLeft = anotherView.middleLeft;

The solution in the selected answer does not work in case of using Autolayout. If you are using Autolayout for views take a look at this answer.


CGRectOffset has since been replaced with the instance method offsetBy.

https://developer.apple.com/reference/coregraphics/cgrect/1454841-offsetby

For example, what used to be

aView.frame = CGRectOffset(aView.frame, 10, 10)

would now be

aView.frame = aView.frame.offsetBy(dx: CGFloat(10), dy: CGFloat(10))

aView.frame = CGRectMake(100, 200, aView.frame.size.width, aView.frame.size.height);

In my work we not use macros. So the solution provide by @TomSwift inspired to me. I see the implementation for CGRectMake and create the same CGRectSetPos but without macros.

CG_INLINE CGRect
CGRectSetPos(CGRect frame, CGFloat x, CGFloat y)
{
  CGRect rect;
  rect.origin.x = x; rect.origin.y = y;
  rect.size.width = frame.size.width; rect.size.height = frame.size.height;
  return rect;
}

To use I only put frame, X and Y

viewcontroller.view.frame = CGRectSetPos(viewcontroller.view.frame, 100, 100);

Work for me ^_^


If anybody needs light Swift extension to change UIView margins easily - you can use this

view.top = 16
view.right = self.width
view.bottom = self.height
self.height = view.bottom

@TomSwift Swift 3 answer

aView.center = CGPoint(x: 150, y: 150); // set center

Or

aView.frame = CGRect(x: 100, y: 200, width: aView.frame.size.width, height: aView.frame.size.height ); // set new position exactly

Or

aView.frame = aView.frame.offsetBy(dx: CGFloat(10), dy: CGFloat(10)) // offset by an amount

Here is the Swift 3 answer for anyone looking since Swift 3 does not accept "Make".

aView.center = CGPoint(x: 200, Y: 200)

Other way:

CGPoint position = CGPointMake(100,30);
[self setFrame:(CGRect){
      .origin = position,
      .size = self.frame.size
}];

This i save size parameters and change origin only.
