ios - Annotation的calloutView上UIButton点击失败

Question

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

首先进行一些解释:1.“SYSUMyAnnoCalloutView”是一个 MKPinAnnotationView 2.“SYSUMyCalloutImageView”是一个 UIImageView，我将其初始化并在“SYSUMyAnnoCalloutView”上 addSubview 3. UIButton 和 UILabel 在“SYSUMyCalloutImageView”中 addSubviewed ”

对应代码: 1. 在“SYSUMyAnnoCalloutView.m”

- (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];
}
}

1. 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];
   

   } 返回 self ； }

有人能解决我的问题吗？我将非常感激:)

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];
