座標中心MapKitView iOS 3.1.3

Question

我如何在iOS 3.1.3中使用座標來定位MapKitView。

與iOS 4 *我用這個代碼，但它無法與iOS 3.1.3

MKCoordinateRegion stopRegion; 
    stopRegion.center = coords; 
    mapView.region = stopRegion; 
    MKCoordinateSpan span; 
    span.latitudeDelta = .005; 
    span.longitudeDelta = .005; 

謝謝！

Answer 1

我發現與iOS 3和4的一個很好的答案工作：

[mapView setRegion:MKCoordinateRegionMake(coords, MKCoordinateSpanMake(.005, .005)) animated:YES]; 

Answer 2

MKCoordinateSpan span; 
span.latitudeDelta = .005; 
span.longitudeDelta = .005; 

MKCoordinateRegion stopRegion; 
stopRegion.center = coords; 
stopRegion.span = span; 

[mapView setRegion:stopRegion animated:YES];
