ios - DidSelect 注解被调用

Question

我有一个点击手势识别器添加到 mapView。我的 MapView 有注释，当我只点击注释时 dismissCollectionView叫做。 DidSelectAnnotation 方法没有被调用。当我点击注释时，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

如果您希望这两种操作都发生 : 设置手势识别器的代理并实现 gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer: 返回 YES用于您的识别器和 map View 内部使用的任何识别器。

如果你想要dismissCollectionView和 mapView:didSelectAnnotationView:互斥 : 实现 -gestureRecognizer:shouldReceiveTouch: 并检查触摸位置是否在 MKAnnotationView或其 subview 之一。只返回YES如果该位置在所有注释 View 之外。
