iOS UI進階-6.0 手勢

標籤：

在開發過程中，經常會用到，需要關閉某個頁面的手勢返回功能。

// 禁用返回手勢- (void)viewDidAppear:(BOOL)animated{    [super viewDidAppear:animated];        // 禁用 返回手勢    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {        self.navigationController.interactivePopGestureRecognizer.enabled = NO;    }}// 開啟手勢- (void)viewWillDisappear:(BOOL)animated{    [super viewWillDisappear:animated];        // 開啟手勢    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {        self.navigationController.interactivePopGestureRecognizer.enabled = YES;    }}// 導覽列返回- (void)blackBtnClick{    // 開啟手勢，有時只在(void)viewWillDisappear:(BOOL)animated開啟，該根欄目下所有的手勢都會失效    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {        self.navigationController.interactivePopGestureRecognizer.enabled = YES;    }        [self.navigationController popToRootViewControllerAnimated:YES];}
