scrollview侧滑返回手势失效 iOS

requireGestureRecognizerToFail 这个方法，是_scrollView等左滑手势失效后，再执行_scrollView内部的手势

解决方案一（推荐）

    [_scrollView.panGestureRecognizer requireGestureRecognizerToFail:self.navigationController.interactivePopGestureRecognizer];

 

解决方案二

    //scrollview侧滑返回手势
    UIScreenEdgePanGestureRecognizer *edgePan = [[UIScreenEdgePanGestureRecognizer alloc] initWithTarget:self action:@selector(handleEdgePan:)];
    edgePan.edges = UIRectEdgeLeft;
    [_scrollView.panGestureRecognizer requireGestureRecognizerToFail:edgePan];
    [_scrollView addGestureRecognizer:edgePan];

 

- (void)handleEdgePan:(UIScreenEdgePanGestureRecognizer *)recognizer {
    [self.navigationController popViewControllerAnimated:YES];
}
