我有一个看起来像这样的视图层次结构:

UIView (A)
UIView > UIImageView
UIView > UIView (B)
UIView > UIView (B) > Rounded Rect Button
UIView > UIView (B) > UIImageView
UIView > UIView (B) > UILabel

我已将手势识别器附加到我的UIView(B).我面临的问题是我没有对UIView(B)中的Rounded Rect Button进行任何操作.singleTap手势识别器捕获/覆盖按钮的Touch Up Inside事件.

我怎样才能使它工作？我认为响应者链层次结构将确保按钮触摸事件将被优先使用,并且它将被触发!我错过了什么？

这是一些相关的代码:

#pragma mark -
#pragma mark View lifecycle (Gesture recognizer setup)

- (void)viewDidLoad {
    [super viewDidLoad];

    // double tap gesture recognizer
    UITapGestureRecognizer *dtapGestureRecognize = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(doubleTapGestureRecognizer:)];
    dtapGestureRecognize.delegate = self;
    dtapGestureRecognize.numberOfTapsRequired = 2;
    [self.viewB addGestureRecognizer:dtapGestureRecognize];

    // single tap gesture recognizer
    UITapGestureRecognizer *tapGestureRecognize = …
