Question

我在我的应用程序中使用MapKit并使用

删除用户位置


[mapview setShowUserLocation:YES];

我想用userLocation的坐标设置region.center.latitude和region.center.longitude，怎么做？

Answer 1

这是我的答案，我尝试了类似的东西及其工作：


//inside my ViewDidLOad
locManager = [[CLLocationManager alloc] init];
[locManager setDelegate:self];
[locManager setDesiredAccuracy:kCLLocationAccuracyBest];
[locManager startUpdatingLocation];

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation  {

   CLLocationCoordinate2D loc = [newLocation coordinate];
   [maptView setCenterCoordiante:loc];  

}

Answer 2

更容易：

-(void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation {
MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(userLocation.location.coordinate, 1500, 1500);
[mapView setRegion:region animated:YES];
}

Answer 3

出于某种原因，这对我不起作用。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];

Answer 4

我认为这回答了你的问题： Returning Mapkit Userlocation Coordinates

（使用mapView.userLocation.location.coordinate.latitude和mapView.userLocation.location.coordinate.longitude properties）

然后将这些坐标注入

-(void)setCenterCoordinate:(CLLocationCoordinate2D)coordinate animated:(BOOL)animated

你的MKMapView实例。

Answer 5

使用代理人：

添加Mapkit委托：MKMapViewDelegate

实现方法：MapView didUpdateUserLocation

-(void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation {
    MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(userLocation.location.coordinate,
        500, 500);
    [mapView setRegion:region animated:YES];
}

没有代表：

[self.mapView setuserTrackingMode:MKUserTrackingModeFollow];

使用MapKit检索UserLocation坐标
