ios - 触摸导航栏时隐藏键盘

Question

我有一个包含四个相关 View 的 UITabBarController。在其中一个 View 中有一个 TextView ，它只为 navigationbar 留出空间:我想做的是在触摸 navigationbar 时隐藏键盘。我怎样才能做到这一点？我应该覆盖 UINavigationBar 的 touchesBegan: 方法吗？

我发现最好的方法是添加一个 UITapGestureRecognizer

UITapGestureRecognizer* tapRecon = [[UITapGestureRecognizer alloc]
                                    initWithTarget:self action:@selector(navigationBarTap:)];
tapRecon.numberOfTapsRequired = 1;
[self.navigationController.navigationBar addGestureRecognizer:tapRecon];

调用方法

- (void)navigationBarTap:(UIGestureRecognizer*)recognizer { 
     [self.view endEditing:YES]; 
}

Answer 1

UITapGestureRecognizer* tapRecon = [[UITapGestureRecognizer alloc]
                                    initWithTarget:self action:@selector(navigationBarTap:)];
tapRecon.numberOfTapsRequired = 1;
[self.navigationController.navigationBar addGestureRecognizer:tapRecon];


- (void)navigationBarTap:(UIGestureRecognizer*)recognizer {
     [self.view endEditing:YES];

    // OR

    for (id view in self.view.subviews) {
        if ([view isKindOfClass:[UITextView class]] || [view isKindOfClass:[UITextField class]]) {
            [view resignFirstResponder];
        }
    }
}

希望这对你有帮助
