ios-MKCoordinateRegion setRegion 問題

MKCoordinateRegion setRegion 問題

在ios5.0中下面的代碼運行正確：

self.mapView = [[[MKMapView alloc]init] autorelease];
mapView.delegate = self;
mapView.frame = CGRectMake(0, 0, 320, 414);
[myView addSubview:mapView];
MKCoordinateRegion zoomRegion = MKCoordinateRegionForMapRect(MKMapRectWorld);
MKCoordinateRegion adjustedRegion = [mapView regionThatFits:zoomRegion];
[mapView setRegion:adjustedRegion animated:NO];

然後我在iphone6.0中運行，就會在[mapView setRegion:adjustedRegion animated:NO];這個地方崩潰。

    *** Terminating app due to uncaught exception 'NSInvalidArgumentException',
 reason: 'Invalid Region <center:+0.00000000, +0.00000000 span:+176.06470039, +360.00004292>'

應該怎麼辦呢？謝謝。

最佳回答：

看起來是[mapView regionThatFits:zoomRegion];引起的問題，刪了它 :

MKCoordinateRegion zoomRegion = MKCoordinateRegionForMapRect(MKMapRectWorld);
   // MKCoordinateRegion adjustedRegion = [self.mapView regionThatFits:zoomRegion];
    [self.mapView setRegion:zoomRegion animated:NO];
