iOS8 UIImageView layer 순서 문제
UIabel 위에 UIImageView 를 올려서
이미지를 라벨 위에 노출되도록 하려고 하는데
iOS7 에서는 문제 없이 노출되는데
iOS8 에서는 UIImageView가 UILabel 밑으로 들어가 버리는 문제가 생겼습니다.
UILabel *trainLabel = [[UILabel alloc] initWithFrame:CGRectMake(10.0, posY, 85, 50)]; [cellView addSubview:trainLabel]; UIImage *noImage = [UIImage imageNamed:@"test.png"]; UIImageView *noImageView = [[UIImageView alloc] initWithImage:noImage]; noImageView.frame = CGRectMake(0, 0, 18.0, 18.0); [trainLabel addSubview:noImageView];

레이어 순서 문제로 보여
Subview들의 layer 순서를 조절할 수 있는 방법을 찾다 보니
다음의 함수를 찾을 수 있었습니다.
- insertSubview:(UIView *) aboveSubview:(UIView *)
Inserts a view above another view in the view hierarchy.
Declaration
SWIFT
func insertSubview(_ view: UIView,
aboveSubview siblingSubview: UIView)
OBJECTIVE-C
- (void)insertSubview:(UIView *)view aboveSubview:(UIView *)siblingSubview
Parameters
view | The view to insert. It’s removed from its superview if it’s not a sibling of |
siblingSubview | The sibling view that will be behind the inserted view. |
Discussion
This method establishes a strong reference to view and sets its next responder to the receiver, which is its new superview.
Views can have only one superview. If view already has a superview and that view is not the receiver, this method removes the previous superview before making the receiver its new superview.
addSubview 대신 insertSubView: aboveSubview 를 이용하여
UIImage *noImage = [UIImage imageNamed:@"test.png"]; UIImageView *noImageView = [[UIImageView alloc] initWithImage:noImage]; noImageView.frame = CGRectMake(trainLabel.frame.origin.x, trainLabel.frame.origin.y, 18.0, 18.0); [cellView insertSubview:noImageView aboveSubview:trainLabel];
위와 같이 수정하니
iOS8에서도 iOS7와 같이 UILabel 위에 UIImageView 를 놓을 수 있었습니다.
조금이나마 도움 되셨기를.... ^^
