MKMapView中天上戳下大头针的效果

MKPinAnnotationView的animatesDrop属性

有大头针没有动画，设置以下animatesDrop=YES

如果想自定义大头针想有动画，那需要参考下面代码自己写个动画

复制代码 #pragma mark MKMapViewDelegate - (void)mapView:(MKMapView *)mapView didAddAnnotationViews:(NSArray *)views {     MKAnnotationView *annotationView;     for (annotationView in views)     {         if (![annotationView isKindOfClass:[MKPinAnnotationView class]])         {             CGRect endFrame = annotationView.frame;             annotationView.frame = CGRectMake(endFrame.origin.x, endFrame.origin.y - 230.0, endFrame.size.width, endFrame.size.height);                          [UIView beginAnimati*****:@"drop" context:NULL];             [UIView setAnimationDuration:0.45];             [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];             [annotationView setFrame:endFrame];             [UIView commitAnimati*****];         }     } }
