ios - 带有自定义标注和按钮的 MKAnnotationView 子类

Question

我目前有一个 StationCalloutView，它是 UIView 的子类(带有 xib)。我还有一个 Station，它是一个 MKAnnotation 和一个 StationAnnotationView，它是 MKAnnotationView 的一个子类。

在 StationAnnotationView 中打开 StationCalloutView 我正在这样做:

- (void)setSelected:(BOOL)selected animated:(BOOL)animated{
    [super setSelected:selected animated:animated];
    if (selected) {
        self.calloutView = [[StationCalloutView alloc] initWithStation:self.annotation];
        if (currentLocation) [self.calloutView calculateDistanceFromLocation:currentLocation];
        [self.calloutView setOrigin:CGPointMake(-self.calloutView.frame.size.width/5.5, -self.calloutView.frame.size.height)];
        [self animateCalloutAppearance];
        [self addSubview:self.calloutView];
    } else {
        [self.calloutView removeFromSuperview];
    }
}

它工作得很好，但现在我想向 StationCalloutView 添加一个按钮，但是当我单击我的 AnnotationView 时，它会自动取消选择，并且不会将任何触摸传递给 StationCalloutView。

有人知道如何实现吗？

实际的解决方案是将此方法(如此处提到的 How To add custom View in map's Annotation's Callout's )添加到 MKAnnotationView 子类:

- (UIView*)hitTest:(CGPoint)point withEvent:(UIEvent*)event
{
    UIView* hitView = [super hitTest:point withEvent:event];
    if (hitView != nil)
    {
        [self.superview bringSubviewToFront:self];
    }
    return hitView;
}

- (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;
}
