Question

我已经在Stackoverflow中搜索过，无法找到SWRevealController和UIGestureRecognizer的特定组合的答案。

在我的iOS项目中，我添加了一个UIGestureRecognizer来打开像菜单一样的菜单。对于类似Facebook的菜单，我使用SWRevealController库：John-Lluch's SWRevealController library。

我还成功添加了带有

的UIGestureRecognizer

[self.view addGestureRecognizer:self.revealViewController.panGestureRecognizer];

工作正常。现在我面临的问题是，我尝试删除此panGestureRecognizer，具体取决于用户是否登录。但是，以下两种情况似乎都不起作用：

 [self.view removeGestureRecognizer:nil];
 [self.view removeGestureRecognizer:self.revealViewController.panGestureRecognizer];

如何将其删除，请帮忙！（我希望我提供了足够的信息，否则请告诉我！谢谢！）

Answer 1

for (UIGestureRecognizer *recognizer in self.view.gestureRecognizers) {
    [self.view removeGestureRecognizer:recognizer];
}

Answer 2

非常奇怪，我来到以下似乎有效的解决方案，感谢Karthik的提示。但是，我仍然认为它是次优的：

bool found = false;
        for (UIGestureRecognizer *recognizer in self.view.gestureRecognizers) {
            if ([[NSString stringWithFormat:@"%@",[recognizer class]] isEqualToString:@"UIScrollViewDelayedTouchesBeganGestureRecognizer"]){
                [self.view removeGestureRecognizer:recognizer];
                found = true;
                break;
            }

        }
        if (!found && self.view.gestureRecognizers.count > 1) {
            [self.view removeGestureRecognizer:self.revealViewController.panGestureRecognizer];
        }

Answer 3

下面的代码解决了我的问题，

while (myView.gestureRecognizers.count) {
    [myView removeGestureRecognizer:[myView.gestureRecognizers objectAtIndex:0]];
}

删除UIGestureRecognizer不起作用
