我使用具有数字值的方法相机,如下所示:
camera = [GMSCameraPosition cameraWithLatitude:37.35 longitude:-122.0 zoom:6];
我需要通过计时器自动重绘当前位置的地图:
-(void)gmapRedraw{
NSLog(@"gmapRedraw");
// self.MapView.camera
[locationManager startUpdatingLocation];
NSLog(@"lat %f, lon %f", locationManager.location.coordinate.latitude, locationManager.location.coordinate.longitude);
camera = [GMSCameraPosition cameraWithLatitude:locationManager.location.coordinate.latitude//37.36//-37.81319//-33.86
longitude:locationManager.location.coordinate.longitude//-122.0//144.96298//151.20
zoom:6];
self.MapView.camera = camera;
}
-(void)timer{
[NSTimer scheduledTimerWithTimeInterval:0.5
target:self
selector:@selector(gmapRedraw)
userInfo:nil
repeats:YES];
}
但是如果我通过触摸更改它,我如何获得当前缩放?
