我想禁用整个视图上的用户交互，但也允许视图上的点击手势。假设主视图上方有一个菜单，如果用户再次点击主视图，后菜单就会消失。但是，只要显示菜单，就应该禁用与主视图的所有其他交互。这是我尝试这样做的方法：我像这样定义了 tapGestureRecognizer：

@interface GroupMasterViewController () <SWRevealViewControllerDelegate>

@property NSMutableArray *groups;
@property (nonatomic, strong) UITapGestureRecognizer *tapGestureRecognizer;

@end

在我的 ViewDidLoad 方法中，我有这个：

self.tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self.revealViewController action:@selector(rightRevealToggle:)];
[self.view addGestureRecognizer:self.tapGestureRecognizer];
self.tapGestureRecognizer.enabled = NO;

在菜单打开或关闭时触发的委托方法中：

- (void)revealController:(SWRevealViewController *)revealController willMoveToPosition:(FrontViewPosition)position
{
    if (position == FrontViewPositionLeftSide) {
        self.tapGestureRecognizer.enabled = YES;
        self.view.userInteractionEnabled = NO;
        self.tabBarController.tabBar.userInteractionEnabled = NO;
    }
    else if (position == FrontViewPositionLeft){
        self.tapGestureRecognizer.enabled = NO;
        self.view.userInteractionEnabled = YES;
        self.tabBarController.tabBar.userInteractionEnabled = YES;

    }
}

问题是如果我禁用用户交互，tapGestureRecognizer 将不再工作。

预先感谢您的任何帮助。

如果您在禁用用户交互的同时尝试启用，那将是冲突tapGestureRecogizer的，所以在我看来，这是最直接的解决方案：与其关闭整个视图的用户交互，您应该对每个视图执行此操作不想对触动做出反应。例如：

- (void)revealController:(SWRevealViewController *)revealController willMoveToPosition:(FrontViewPosition)position
{
    if (position == FrontViewPositionLeftSide) {
        self.tapGestureRecognizer.enabled = YES;
        self.button1.userInteractionEnabled = NO;
        self.button2.userInteractionEnabled = NO;
        self.tabBarController.tabBar.userInteractionEnabled = NO;
    }
    else if (position == FrontViewPositionLeft){
        self.tapGestureRecognizer.enabled = NO;
        self.button1.userInteractionEnabled = YES;
        self.button2.userInteractionEnabled = YES;
        self.tabBarController.tabBar.userInteractionEnabled = YES;

    }
}

我认为不可能禁用用户交互然后期待一些用户交互事件。您可以progress bar针对特定事件显示以防止用户交互。
