Iphone 使用span缩放到用户位置

如果需要,我可以发布头文件。我主要关心的是缩放。我只是不明白为什么它不起作用。你的-(void)locationManager:(CLLocationManager*)manager的代码没有更新到location:(CLLocation*)newLocation fromLocation:(CLLocation*)oldLocation
似乎是对的
试着换线
[self.view insertSubview:mapView atIndex:0];
致:
可能是由于视图中的显示方式,MKMapView
没有重新绘制自身。您的-(void)locationManager:(CLLocationManager*)管理器didUpdateToLocation:(CLLocation*)newLocation fromLocation:(CLLocation*)oldLocation
的代码似乎是正确的
试着换线
[self.view insertSubview:mapView atIndex:0];

可能是因为
MKMapView
在视图中的显示方式,它没有重新绘制自身。工作得很好。谢谢。现在我注意到另一个问题。改变那条线现在隐藏了我在地图上的一个uibutton。我需要在地图视图的顶部添加另一个子视图吗?对不起,我已经解决了。再次感谢您的回复。效果非常好。谢谢。现在我注意到另一个问题。改变那条线现在隐藏了我在地图上的一个uibutton。我需要在地图视图的顶部添加另一个子视图吗?对不起,我已经解决了。再次感谢您的回复。
