我试图在MKMapKit中返回用户位置,但是在LOG中,它总是返回0.0000,0.0000。当项目运行时,它会在地图上显示userLocation ..但是在log show 0,0 ..
有些人知道怎么做吗?看看我的代码:- (void)viewDidLoad
{ [super viewDidLoad];
//esconder navBar
[[self navigationController] setNavigationBarHidden:YES animated:NO];
mapView.showsUserLocation = YES;
double lat = -21.21258;
double lng = -47.816802;
CLLocationCoordinate2D Coordinate;
NSLog(@"%f , %f", mapView.userLocation.coordinate.longitude, mapView.userLocation.coordinate.latitude);
Coordinate.latitude = lat;
Coordinate.longitude = lng;
MKPointAnnotation *annotationPoint = [[MKPointAnnotation alloc] init];
annotationPoint.coordinate = Coordinate;
annotationPoint.title = @"Ribeirão Shopping";
annotationPoint.subtitle = @"Ribeirão Preto - SP";
[self.mapView addAnnotation:annotationPoint];
MKCoordinateRegion newRegion;
newRegion.center.latitude = lat;
newRegion.center.longitude = lng;
[self.mapView setRegion:newRegion animated:YES];
mapView.mapType = MKMapTypeStandard;
}
谢谢!

查找mapview的用户位置确实需要一些时间,所以在使用mapView.userlocaiton
git几秒~3之前给它一些时间,然后尝试记录用户位置。我相信你会在那里得到它。
