ios4 - 放大地图视图

Question

Mapview 应该以放大模式启动特定引脚。我们如何以编程方式做到这一点。任何委托方法都可以做到这一点。

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];
