iOS6 MKMapView縮放

Question

我試圖讓我的MKMapView放大到註釋。我嘗試了各種嘗試，但仍保持縮小到我的region。

- (void)mapView:(MKMapView *)mapView didAddAnnotationViews:(NSArray *)views 
{ 
    NSLog(@"Did add annotations"); 
    MKAnnotationView *annotationView = [views objectAtIndex:0]; 
    id <MKAnnotation> mp = [annotationView annotation]; 
    MKCoordinateSpan span; 
    span.longitudeDelta = 0.02; 
    span.latitudeDelta = 0.02; 
    MKCoordinateRegion region; 

    region.center = mapView.userLocation.coordinate; 
    region.span = span; 

    [mapView selectAnnotation:mp animated:YES]; 
    [self.spotMapView setRegion:region animated:YES]; 
    [self.spotMapView regionThatFits:region]; 
} 

哪個運行，但地圖保持縮小。

Answer 1

更改didAddAnnotationViews這樣：

- (void)mapView:(MKMapView *)mapView didAddAnnotationViews:(NSArray *)views 
{ 
    NSLog(@"Did add annotations"); 
    MKAnnotationView *annotationView = [views objectAtIndex:0]; 
    id <MKAnnotation> mp = [annotationView annotation]; 
    [mapView selectAnnotation:mp animated:NO]; 
} 

似乎做的伎倆，地圖縮放現在在
