iOS 禁止某个页面侧滑返回

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

直接粘贴到viewDidLoad完事。
