    [self setMapView:mapView]; 

    MKCoordinateRegion region; 

region.center.latitude = 41.603854; 
    region.center.longitude = -92.930628; 
    region.span.longitudeDelta = 47.00; 
    region.span.latitudeDelta = 10.00; 

Answer 1

需要，一旦你設置設置區域它起來。

region.center.latitude = 41.603854; 
region.center.longitude = -92.930628; 
region.span.longitudeDelta = 47.00; 
region.span.latitudeDelta = 10.00; 

[mapView setRegion:region animated:YES];
