Ios SingleTapOnMap方法未在iphone中调用

我正在使用下面的代码与MBTiles交互。但当我在iphone上运行singleTapOnMap方法时，它并没有调用。我还添加了一个拖车，它正在TileMill上工作，但在iPhone上没有。我是否出了什么差错

//ViewController.h

@interface ViewController : UIViewController<RMMapViewDelegate>

@end

    RMMapView *mapView = [[RMMapView alloc] initWithFrame:self.view.bounds andTilesource:offlineSource];

    mapView.zoom = 2;

    mapView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;

    mapView.adjustTilesForRetinaDisplay = YES; // these tiles aren't designed specifically for retina, so make them legible

您必须分配代理协议：

mapView.delegate = self;

viewDidLoad中缺少

mapView.delegate=self；
