ios - MKPolylineView initWithPolyLine : is deprecated in iOS 7

Question

我收到以下错误:initWithPolyline: is deprecated: first deprecated in iOS 7.0

MKPolylineView *lineView = [[MKPolylineView alloc] 
       initWithPolyline:overlay];

instead of this 的替换方法是什么？

Answer 1

您应该使用(MKOverlayRenderer *) 类型委托(delegate)而不是(MKOverlayView *) 类型委托(delegate)。并返回 MKPolylineRenderer 而不是 MKPolylineView。

-(MKOverlayRenderer *)mapView:(MKMapView *)mapView
           rendererForOverlay:(id<MKOverlay>)overlay {

   MKPolylineRenderer *renderer = [[MKPolylineRenderer alloc] initWithOverlay:overlay];
   renderer.strokeColor = [UIColor redColor];
   renderer.lineWidth = 5.0;

   return renderer;
}
