iOS 左滑返回与UIScrollView左右滑动冲突

0x00

一行代码：

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

还应该在生命周期方法内处理一下：

- (void)viewDidDisappear:(BOOL)animated{
    [super viewDidDisappear:animated];   
    self.navigationController.interactivePopGestureRecognizer.enabled = YES;
}

0x01

如果你页面过于复杂，试试下面这个方法

    NSArray *gestureArray = self.navigationController.view.gestureRecognizers;
    for (UIGestureRecognizer *gesture in gestureArray) {
        if ([gesture isKindOfClass:[UIScreenEdgePanGestureRecognizer class]]) {
            [_scrollView.panGestureRecognizer requireGestureRecognizerToFail:gesture];
        }
    }

这个心形遮罩有点意思
