【问题描述】：

我遇到的问题：我点击了按钮，但似乎是 CalloutView 收到了我的点击，而不是 UIButton。

首先解释一下： 1.“SYSUMyAnnoCalloutView”是一个 MKPinAnnotationView 2.“SYSUMyCalloutImageView”是一个 UIImageView，我初始化它并在“SYSUMyAnnoCalloutView”上添加Subview 3. UIButton 和 UILabel 在“SYSUMyCalloutImageView”中添加Subviewed "

对应代码： 1.在“SYSUMyAnnoCalloutView.m”中

- (void)setSelected:(BOOL)selected animated:(BOOL)animated

if (selected)
    [self.calloutImageView setFrame:CGRectMake(-75, -100, 230, 130)];

    [self animateCalloutAppearance];
    //[self.calloutImageView becomeFirstResponder];
    //[self.calloutImageView.detailButton addTarget:self.calloutImageView action:@selector(clickForDetail) forControlEvents:UIControlEventTouchUpInside];
    [self addSubview:self.calloutImageView];
    [self setCanShowCallout:NO];

else

    //Remove your custom view...
    [self.calloutImageView removeFromSuperview];

在“SYSUMyCalloutImageView.m”中

- (id)initWithImage:(UIImage *)image

self = [super initWithImage:image];
if (self)
    //Label
CGRect boundsForLabel;
boundsForLabel.origin.x = 20;
boundsForLabel.origin.y = 50;
boundsForLabel.size.width = self.bounds.size.width - 100;
boundsForLabel.size.height = 20;
self.messageLabel = [[UILabel alloc] initWithFrame:boundsForLabel];
self.messageLabel.backgroundColor = [UIColor clearColor];
[self addSubview:self.messageLabel];
//detailButton
CGRect buttonRect;
buttonRect.origin.x = 20;
buttonRect.origin.y = 80;
buttonRect.size.width = boundsForLabel.size.width-50;
buttonRect.size.height = 30;
self.detailButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[self.detailButton setFrame:buttonRect];
[self.detailButton setTitle:@"Click for detail" forState:UIControlStateNormal];
self.detailButton.userInteractionEnabled = YES;
//[self.detailButton addTarget:self.superview action:@selector(clickForDetail) forControlEvents:UIControlEventTouchUpInside];
[self addSubview:self.detailButton];

回归自我；

谁能解决我的问题？？将不胜感激:)

【参考方案1】：

默认情况下 UIImageView 不接受用户交互。

您应该尝试在 SYSUMyCalloutImageView.m 的 initWithImage 中添加这行代码

[self setUserInteractionEnabled:YES];
