iOS 禁用右滑返回手势

可以通过设置页面的VC.navigationController.interactivePopGestureRecognizer.enabled来控制当前页面的右滑返回手势是否可用。可以创建一个UIViewController 的分类创建两个类方法。

+ (void)popGestureClose:(UIViewController *)VC
{
    // 禁用侧滑返回手势
    if ([VC.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        //这里对添加到右滑视图上的所有手势禁用
        for (UIGestureRecognizer *popGesture in VC.navigationController.interactivePopGestureRecognizer.view.gestureRecognizers) {
            popGesture.enabled = NO;
        }
    }
}

+ (void)popGestureOpen:(UIViewController *)VC
{
    // 启用侧滑返回手势
    if ([VC.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        //这里对添加到右滑视图上的所有手势启用
        for (UIGestureRecognizer *popGesture in VC.navigationController.interactivePopGestureRecognizer.view.gestureRecognizers) {
            popGesture.enabled = YES;
        }
    }
}

在viewDidAppear:中禁用手势，viewWillDisappear:中开启手势。

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
    [UIViewController popGestureClose:self];
}

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    [UIViewController popGestureOpen:self];
}
