iOS开发技巧之：iOS 单个页面禁用侧滑返回（禁用手势退出）

方法一 OC：

- (void)viewDidLoad {
    [super viewDidLoad];
    id traget = self.navigationController.interactivePopGestureRecognizer.delegate;
    UIPanGestureRecognizer * pan = [[UIPanGestureRecognizer alloc]initWithTarget:traget action:nil];
    [self.view addGestureRecognizer:pan];
}

方法二 Swift：

  override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        UIApplication.shared.isIdleTimerDisabled = true
        self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false;
    }

    override func viewDidDisappear(_ animated: Bool) {
        super.viewDidDisappear(animated)
        UIApplication.shared.isIdleTimerDisabled = false
        self.navigationController?.interactivePopGestureRecognizer?.isEnabled = true;
    }

方法三：

• 先写一个UIViewController分类

+ (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;
        }
    }
}

• 再在控制器里使用

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

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