如何更改视图，而我们接触任何注解

问题描述

我想在的MKMapView添加功能。

I want to add a functionality in MKMapView .

我有很多注释的图形页面现在我想的..当我接触任何注解整个视图应侧重于注释。即注解的是在右上角，当我接触到的MapView应表明，在中心即可。

I have a mapView with many annotations now I want that .. when I touch any annotation the whole view should be focus on that annotation . i.e. annotation A is in the upper right corner and when I touch that the MapView should show that A in the centre then .

推荐答案

在注释代表你必须设置香港特别行政区的MapView指定中心

In Annotation Delegate you have to set the Region for mapview specifying the center

- (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
}
