I tried to use tiled map in ios7 using the method that provided in wwdc, but it doesn't appear anything. Anyone has sample code for that? My code is provided below
#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
NSString *template = @"http://c.tile.openstreetmap.org/{z}/{x}/{y}.png";
MKTileOverlay *overLay = [[MKTileOverlay alloc] initWithURLTemplate:template];
overLay.canReplaceMapContent = YES;
[self.mapView addOverlay:overLay level:MKOverlayLevelAboveLabels];
[self.mapView setRegion:MKCoordinateRegionMake(CLLocationCoordinate2DMake(37.776884, -122.387255), MKCoordinateSpanMake(0.25, 0.25))];
}
-(MKTileOverlayRenderer *)mapView:(MKMapView*)mapView rendererForOverlay:(id<MKOverlay>)overlay {
MKTileOverlayRenderer *renderer = [[MKTileOverlayRenderer alloc] initWithOverlay:overlay];
renderer.alpha = 0.6;
return renderer;
Did you set your mapView's delegate to self? Because if not, the -rendererForOverlay won't get called.
