iOS 使用多个滑动识别器

Question

我的 View 上有左右滑动识别器以及表格。当用户在表格 View 上向左->向右滑动时，表格处理它们并滑动表格内容而不是执行向左->，就会出现问题右滑动识别器方法。如何提高左->右滑动识别器的灵敏度？

这是识别器的代码:

UISwipeGestureRecognizer *swipeRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeRight)];

swipeRecognizer.numberOfTouchesRequired = 1;

swipeRecognizer.direction = UISwipeGestureRecognizerDirectionRight;

[self.view addGestureRecognizer:swipeRecognizer];

UISwipeGestureRecognizer *swipeRecognizer1 = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeLeft)];

swipeRecognizer1.direction = UISwipeGestureRecognizerDirectionLeft;

swipeRecognizer1.numberOfTouchesRequired = 1;

[self.view addGestureRecognizer:swipeRecognizer1];

Answer 1

您可以要求一个gestureRecognizer在调用另一个gestureRecognizer之前失败。

[lowerPriorityGestureRecognizer requireGestureRecognizerToFail:higherPriorityGestureRecognizer];
