ios - UICollectionView 滑动

Question

我想检测用户何时在一个单元格占据整个屏幕宽度的 collectionView 中向左或向右滑动。是否可以不添加手势识别器。我试过添加手势识别器，但只有当我们将 collectionView 的 scrollEnabled 属性设置为 NO 时它才有效。

UISwipeGestureRecognizer *swipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(didSwipeRight:)];
swipeRight.delegate = self;
swipeRight.numberOfTouchesRequired = 1;
[swipeRight setDirection:UISwipeGestureRecognizerDirectionRight];

UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(didSwipeLeft:)];
swipeLeft.delegate = self;
swipeLeft.numberOfTouchesRequired = 1;
[swipeLeft setDirection:UISwipeGestureRecognizerDirectionLeft];

[self.collectionView addGestureRecognizer:swipeLeft];
[self.collectionView addGestureRecognizer:swipeRight];

Answer 1

也许您禁用了 userInteraction。你检查了吗？并将手势定义为类的属性。

self.collectionView.setUserInteractionEnabled=true;
