推荐答案

要隐藏标注所有你需要做的是取消选择的注释。你这样做，通过使用...

To hide the callout all you need to do is deselect the selected annotation. You do that by using...

- (void)deselectAnnotation:(id < MKAnnotation >)annotation animated:(BOOL)animated

例如：

[mapView deselectAnnotation:[mapView.selectedAnnotations objectAtIndex:0] animated:YES];

假设图形页面是你命名了的MKMapView实例。

assuming mapView is what you named your MKMapView instance.
