ios - IOS。如何在使用此地图的每个操作后获取有关当前地图矩形的信息？

比如我想显示地图rect当前的x,y,宽高，但是不知道应该处理什么事件。至少我想捕捉双击、缩放和拖动。

检查MKMapViewDelegate协议的文档。你有这些可用的方法：http: //developer.apple.com/library/ios/#documentation/MapKit/Reference/MKMapViewDelegate_Protocol/MKMapViewDelegate/MKMapViewDelegate.html

– mapView:regionWillChangeAnimated:
– mapView:regionDidChangeAnimated:
– mapViewWillStartLoadingMap:
– mapViewDidFinishLoadingMap:
– mapViewDidFailLoadingMap:withError:
– mapViewWillStartLocatingUser:
– mapViewDidStopLocatingUser:
– mapView:didUpdateUserLocation:
– mapView:didFailToLocateUserWithError:
– mapView:viewForAnnotation:
– mapView:didAddAnnotationViews:
– mapView:annotationView:calloutAccessoryControlTapped:
– mapView:annotationView:didChangeDragState:fromOldState:
– mapView:didSelectAnnotationView:
– mapView:didDeselectAnnotationView:
– mapView:viewForOverlay:
– mapView:didAddOverlayViews:

此外，MKMapView继承自UIScrollView，因此通过将自己设置为委托，您还可以采用UIScrollViewDelegate协议，并使用这些方法：http: //developer.apple.com/library/ios/#documentation/UIKit/Reference/UIScrollViewDelegate_Protocol/Reference/ UIScrollViewDelegate.html
