如何跟踪点击时正确的标注附件视图在何处 [英] How to track where the right callout accessory view is when it was tapped on

问题描述

正如您在下面看到的，我有一个带有右键的注释视图.当用户点击右按钮时，我将显示一个弹出框-问题是我不知道用户在哪里轻按，因此我没有X和Y来显示相应的弹出框.

As you can see below I have an annotation view that has a right button. When the user taps the right button I am presenting a popover - the problem is I don't know where the user tapped so I don't have the X and Y to display the popover accordingly.

我如何找出用户点击的位置，即X和Y?

How do I find out where the user tapped i.e. the X and Y?

HotelAnnotationView *customPinView = [[HotelAnnotationView alloc] initWithAnnotation:theHotel reuseIdentifier:hotelPin];

//The right button which allows user to see hotel information
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeInfoLight];
[rightButton addTarget:self action:@selector(showDetailsForHotel:) forControlEvents:UIControlEventTouchUpInside];

rightButton.tag = theHotel.id;
customPinView.rightCalloutAccessoryView = rightButton;

推荐答案

简单实施

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control

每当用户单击calloutAccessoryControl时，将在您的代理上呼叫该呼叫.然后，您可以通过

Which will get called on your delegate everytime a user taps the calloutAccessoryControl. You can then access you annotation properties through

view.annotation

与使用(id)sender相比，我更喜欢这种方法的原因是，您实际上不仅可以访问注释lat&长坐标，但实际上有任何与其相关的数据，因此您可以在弹出视图中使用它.

The reason I like this approach better than using the (id)sender is that you actually get access to not only your annotation lat & long coordinates, but any data that is actually associated with it so you can use that in your pop over view.
