UINavigationViewController interactivePopGestureRecognizer

来源：互联网发布：淘宝免费买东西的软件编辑：程序博客网时间：2024/06/05 15:43

如何打开交互手势，在自定义返回按钮的情况下

self.navigationController.interactivePopGestureRecognizer.enable = YES;

self.navigationController.interactivePopGestureRecognizer.delegate = self

开发中遇到的问题， UIWebView 的情况下，如何支持交互手势

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{    return YES;}- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldBeRequiredToFailByGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{    return [gestureRecognizer isKindOfClass:UIScreenEdgePanGestureRecognizer.class];}


for (UIGestureRecognizer *gestureRecognizer in _colView.gestureRecognizers) {        [gestureRecognizer requireGestureRecognizerToFail:self.navigationController.interactivePopGestureRecognizer];    }

应该避免的问题
