我有一个包含MKMapView的UIViewController(事实上,它包含一个包含MKMapView的全屏容器,但它不应该有任何影响)
我实现了一个UIScreenEdgePanGestureRecognizer(显示抽屉),如下所示：
self.swipeRight = [[UIScreenEdgePanGestureRecognizer alloc] initWithTarget:self action:@selector(handleEdgeGesture:)]; [self.swipeRight setEdges:UIRectEdgeLeft]; [self.swipeRight setDelegate:self]; [self.view addGestureRecognizer:self.swipeRight];
(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer;
但随后地图在抽屉出现的同时移动！
我已经尝试过各种各样的技巧来阻止它但是却无法……(我试过了例如shouldBerequiredToFailByGestureRecognizeror requireGestureRecognizerToFail)
有什么想法,当手势是来自LeftEdge的ScreenEdgePan时,我怎么能阻止MapView移动？
解决方法
我在我的应用程序中所做的是以下内容：
UIScreenEdgePanGestureRecognizer *popRecognizer = [[UIScreenEdgePanGestureRecognizer alloc] initWithTarget:self action:@selector(handlePopRecognizer:)]; popRecognizer.edges = UIRectEdgeLeft; popRecognizer.delegate = self;
然后如你所说,将委托设置为YES
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
return YES;
}
并启用/禁用这样的mapview滚动
- (void)handlePopRecognizer:(UIScreenEdgePanGestureRecognizer*)recognizer
{
if(recognizer.state == UIGestureRecognizerStateBegan){
_mapView.scrollEnabled = NO;
} else if(recognizer.state == UIGestureRecognizerStateEnded || recognizer.state == UIGestureRecognizerStateCancelled){
_mapView.scrollEnabled = YES;
}
}
希望能帮助到你.
