UIButton未能在注释的calloutView上单击

Question

​

​

​

​

我遇到的问题是:我点击按钮，但是CalloutView似乎收到了我的点击而不是UIButton。

首先要解释一下:1. "SYSUMyAnnoCalloutView“是MKPinAnnotationView 2. "SYSUMyCalloutImageView”是UIImageView，我在"SYSUMyAnnoCalloutView“一书中给它加上了addSubview 3. UIButton和UILabel在"SYSUMyCalloutImageView”中是addSubviewed

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];
}
}

1. 在"SYSUMyCalloutImageView.m“中

• (id)initWithImage:(UIImage *)图像{ self = super :image；if ( self ){ //Label CGRect boundsForLabel；界sForLabel.initi.x= 20；finsForLabel.Sour.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；//细节buttonRect buttonRect；扣onRect.Sour.x= 20；boundsForLabel.size.width= 80；buttonRect.size.width =adesForLabel.size-50；buttonRect.size.height = 30；self.detailButton = UIButton按钮-setFrame:UIButtonTypeRoundedRect；self.detailButton setFrame:buttonRect；self.detailButton setTitle：@“clickForDetail”forState:UIControlStateNormal；self.detailButton.userInteractionEnabled = YES；//sel.细节UIButton addTarget:self.superview动作：@selector(ClickForDetail)UIControlEventTouchUpInside；self addSubview:self.detailButton； }返回自我；}

有人能解决我的问题吗？将非常感谢：)

默认情况下，UIImageView不接受用户交互。

您应该尝试在SYSUMyCalloutImageView.m的initWithImage中添加这一行代码

[self setUserInteractionEnabled:YES];
