我使用gestureRecognizer进行了PinView。

UITapGestureRecognizer *tapLocation = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(gestureRecognizerShouldBeginFocusMap:)];
    tapLocation.numberOfTapsRequired=1;
    [pinView addGestureRecognizer:tapLocation];

- (BOOL)gestureRecognizerShouldBeginFocusMap:(UIGestureRecognizer *)gestureRecognizer
 {

      MKMapRect visibleMapRect = self.mapView.visibleMapRect;
      NSSet *visibleAnnotations = [self.mapView annotationsInMapRect:visibleMapRect];

      for ( MyAnnotation *annotation in visibleAnnotations ){

          [self setCenterCoordinate:annotation.coordinate zoomLevel:18 animated:YES];

      }

      return YES;
}
