Iphone 显示问题的注释
我创建了一个带有图钉的MKMapView 当我按下pin键时,我会看到标题和副标题,但我希望看到它而不点击。 所以,我希望标题和副标题在地图显示后立即出现 这是我的密码:Iphone 显示问题的注释,iphone,ios,objective-c,mkmapview,mapkit,Iphone,Ios,Objective C,Mkmapview,Mapkit,我创建了一个带有图钉的MKMapView 当我按下pin键时,我会看到标题和副标题,但我希望看到它而不点击。 所以,我希望标题和副标题在地图显示后立即出现 这是我的密码: self.mapView = [[[MKMapView alloc]init] autorelease]; mapView.frame = self.view.bounds; mapView.delegate = self; [self.view addSubview:mapView];

使用MKMapView的
selectAnnotation:animated
方法
[mapView selectAnnotation:YorAnnotation animated:YES];
