如何处理自定义标注视图上的水龙头？

这是因为注释视图仅检测其边界内的触摸。由于您的标注视图超出了范围，因此子视图无法识别点击。您需要

pointInside:withEvent:

这是Objective-C中的一个示例：

- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent*)event{    CGRect rect = self.bounds;    BOOL isInside = CGRectContainsPoint(rect, point);    if (!isInside)    {        for (UIView *view in self.subviews)        { isInside = CGRectContainsPoint(view.frame, point); if (isInside) {     break; }        }    }    return isInside;}

迅捷版：

override func pointInside(point: CGPoint, withEvent event: UIEvent?) -> Bool {    let rect = self.bounds    var isInside = CGRectContainsPoint(rect, point)    if (!isInside) {        for subview in subviews { isInside = CGRectContainsPoint(subview.frame, point) if (isInside) {     break }        }    }    println(isInside)    return isInside;}
