如何将地图视图设置为自动放大用户的当前位置？

Question

当我点击标签栏中的"Map"按钮时，它会弹出我的地图视图控制器，并显示用户在mapview上的当前位置(我使用以下代码):

[mapview setShowsUserLocation:YES];

超级容易。但如果我想让地图自动放大用户的当前位置，我该怎么做(在xCode中)?

谢谢:)

Answer 1

我想这就是你需要的

  - (void)viewDidLoad
 {
    [super viewDidLoad];
    self.mapView.showsUserLocation=YES;
    self.mapView.delegate = self;
    [self.mapView setUserTrackingMode:MKUserTrackingModeFollow animated:YES];
    //some code
 }

Answer 2

[mapview setUserTrackingMode:MKUserTrackingModeFollow];

Answer 3

这应该是你正在寻找的

    MKCoordinateRegion region;
    region = (MKCoordinateRegion){(current user location).location.coordinate, (current user location).locationCoordinateSpan};        
    [theMapView setRegion:region animated:NO/YES];
