DidSelect Annotation被调用

Question

我在地图视图中添加了一个点击手势识别器。我的MapView有注释，当我点击注释时，只调用dismissCollectionView。 DidSelectAnnotation方法没有被调用。点击注释时如何停止tapgesture方法（dismisscollection）调用？任何帮助将不胜感激。

self.m_mapView = [[MKMapView alloc] init];
    self.m_mapView.frame = CGRectMake(0, 0, 320, 568);
    self.m_mapView.delegate = self;

   // MapHeight = self.m_mapView.frameHeight;

    m_locationManager = [[CLLocationManager alloc] init];

    if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")) {
        [m_locationManager requestWhenInUseAuthorization];
        [m_locationManager requestAlwaysAuthorization];
    }
    self.m_mapView.mapType = MKMapTypeStandard;
    [self.m_mapView setUserTrackingMode:MKUserTrackingModeFollow];
    [self.m_bgImageView addSubview:self.m_mapView];

    m_locationManager.desiredAccuracy = kCLLocationAccuracyBest;
    m_locationManager.delegate = self;


    UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(dismissCollectionView)];
    tapGesture.numberOfTouchesRequired = 1;
    tapGesture.cancelsTouchesInView = NO;
    [self.m_mapView addGestureRecognizer:tapGesture];

Answer 1

如果您希望同时执行这两项操作：设置手势识别器的代理并实施gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer:以返回识别器的YES以及地图视图内部使用的任何内容

如果您希望dismissCollectionView和mapView:didSelectAnnotationView:互斥：实施-gestureRecognizer:shouldReceiveTouch:并检查触摸位置是否在MKAnnotationView或其中一个子视图。如果位置在所有注释视图之外，则仅返回YES。
