如何在觸摸任何註釋時更改視圖

Question

我想在MKMapView中添加功能。

我現在有一個帶有許多註釋的mapView我想要..當我觸及任何註釋時，整個視圖應該關注該註釋。即註釋A位於右上角，當我觸摸MapView應該在中心顯示A時。

Answer 1

在註釋代表你必須設置該地區的MapView指定中心

- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view 
{ 
    MKAnnotation *annotation= view.annotation; // Get your annotaion here 
    MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } }; 
    region.center.latitude=annotation.coordinate.latitude; 
    region.center.longitude=annotation.coordinate.longitude; 
    region.span.latitudeDelta=0.001f; 
    region.span.longitudeDelta=0.001f; 
    [mapView setRegion:region animated:YES]; 
    //Do your other stuffs here 
} 

Answer 2

- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view 
{ 
    MKAnnotation *annotation= view.annotation; // Get your annotaion here 
    [map setCenterCoordinate:annotation.coordinate]; 
} 

//This will set the annotation in the centre of the map without zooming the map.
