返回Mapkit Userlocation坐标

Question

每当我尝试返回当前位置的纬度/经度坐标时，我的应用程序崩溃而没有解释错误......

NSLog(@"%@", mapView.userLocation.location.coordinate);

我在等电话找到位置......

Answer 1

mapView.userLocation.location.coordinate是一个结构，而%@格式说明符需要一个对象。这将有效：

NSLog(@"%f, %f", mapView.userLocation.location.coordinate.latitude,
                 mapView.userLocation.location.coordinate.longitude);

Answer 2

出于某种原因，这对我没有用。它带我到坐标（0.0000,0.0000）。如果您有机会查看，我的代码如下。谢谢你的帮助！

[mapView setMapType:MKMapTypeStandard];
    [mapView setZoomEnabled:YES];
    [mapView setScrollEnabled:YES];
    mapView.showsUserLocation=TRUE;

    MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } };

    CLLocationCoordinate2D myCoord = {mapView.userLocation.location.coordinate.latitude,mapView.userLocation.location.coordinate.longitude};
    [mapView setCenterCoordinate:myCoord animated:YES];

    region.span.longitudeDelta = 0.01f;
    region.span.latitudeDelta = 0.01f;
    [mapView setRegion:region animated:YES]; 

    [mapView setDelegate:self];
