iOS-某个页面禁止侧滑手势返回

1.在视图已经出现时设置:

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
    //隐藏返回按钮
    self.navigationItem.hidesBackButton = YES;
    //禁止页面左侧滑动返回，注意，如果仅仅需要禁止此单个页面返回，还需要在viewWillDisapper下开放侧滑权限
    // 禁用返回手势
    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        self.navigationController.interactivePopGestureRecognizer.enabled = NO;
    }
}

2.在视图已经消失时设置：

- (void)viewDidDisappear:(BOOL)animated {
    [super viewDidDisappear:animated];
    // 开启返回手势
    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        self.navigationController.interactivePopGestureRecognizer.enabled = YES;
    }
}
