Re: When I rotate the MKMapView with transform, setCenter not working.
Hi,
I have solved this problem.
Do not change the frame of map view when it’s transform does not equal to
CGAffineTransformIdentity.

When I rotate the MKMapView with transform, setCenter not working.
Hi all,
I rotate the MKMapView with setting the rotation transform. When I use
setCenter method to change the center coordinate of the map, the location of
this coordinate not in the center. Does anyone know what happened, and how to
solve this problem? Below is the code snipt.
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
static CLLocationCoordinate2D aircraftCoordinate = {22.531474, 113.943516};
CGFloat width = self.view.bounds.size.width;
CGFloat height = self.view.bounds.size.height;
CGFloat newSize = sqrt(width* width + height * height);
UIView *tmpView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, width,
height)];
[self.view insertSubview:tmpView atIndex:0];
self.containorView = tmpView;
MKMapView *tmpMapView = [[MKMapView alloc] initWithFrame:CGRectMake(0, 0,
newSize, newSize)];
[self.containorView addSubview:tmpMapView];
self.mapView = tmpMapView;
[tmpMapView setCenter:self.containorView.center];
self.annotation = [[DJITestAnnotation alloc] init];
_annotation.coordinate = aircraftCoordinate;
[self.mapView addAnnotation:self.annotation];
self.mapView.delegate = self;
[self.mapView setTransform:CGAffineTransformMakeRotation(90 * M_PI_4 /
180)];
}
- (IBAction)location:(id)sender {
self.mapView.camera.centerCoordinate = _annotation.coordinate;
}

Sunny Lee
