在MKAnnotationView中检测对CalloutBubble的点击 [英] Detect Tap on CalloutBubble in MKAnnotationView

问题描述

我正在使用MKMapView和MKAnnotationView.

Im working with MKMapView and MKAnnotationView.

我在地图上有一个注释.当用户点击它时，将显示标注气泡.当再次点击注释(并且可以看到callOut气泡)时，我需要切换到另一个视图.

I have an annotation in the map. When the users tap on it, the callOut Bubble is displayed. When the annotation is tapped again ( and the callOut Bubble is visible ) i need to change to another view.

如何检测第二次点击或气泡中的点击?

How can i detect the second tap, or the tap in the bubble?

推荐答案

初始化MKAnnotationView时可以添加手势识别器吗?

Could you add a gesture recognizer when you're initializing the MKAnnotationView?

这是dequeueReusableAnnotationViewWithIdentifier:

UITapGestureRecognizer *tapGesture = 
        [[UITapGestureRecognizer alloc] initWithTarget:self 
                                        action:@selector(calloutTapped:)];
[theAnnotationView addGestureRecognizer:tapGesture];
[tapGesture release];

手势识别器的方法:

-(void) calloutTapped:(id) sender { 
    // code to  display whatever is required next.

    // To get the annotation associated with the callout that caused this event:
    // id<MKAnnotation> annotation = ((MKAnnotationView*)sender.view).annotation;
}
