ZoomIn for Mapview

Question

Mapview應該以縮放模式啓動特定引腳。我們如何以編程方式來做到這一點。任何代表方法都在那裏。

Answer 1

MKMapView * mvMap; 

MKCoordinateRegion region; 
region.center.longitude = 0; 
region.center.latitude = 0; 
region.span.latitudeDelta = 5; // this is zoom level 
region.span.longitudeDelta = 5; 

[mvMap setRegion:region animated:NO]; 
[mvMap regionThatFits:region];
