ios - 当没有要 resignFirstResponder 的文本字段时如何关闭键盘

Question

在以下情况下，单击铅笔将 iz 1 文本设置为可编辑，becomeFirstResponder并打开键盘，我希望在单击“空行”或 iz2 时关闭键盘。

我怎样才能做到这一点？

我试过添加到 cellView

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
    [self dismissKeyboard];
}

但它没有用

Answer 1

您可以使用以下方法隐藏键盘：

[self.view endEditing:YES];

编辑

在可以调用的地方添加手势becomeFirstResponder。

- (void)showKeyboard
{
    UITapGestureRecognizer *gesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hide)];
    [self.tableView addGestureRecognizer:gesture];
}

并在 hide 方法中将其删除，

- (void)hide
{
    [self.view endEditing:YES];
    [self.view removeGestureRecognizer:self.view.gestureRecognizers[0]];
}

Answer 2

只需致电：

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [self.view endEditing:YES];
}

或者：

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSIndexPath *indexPathForYourCell = [NSIndexPath indexPathForRow:0 inSection:0];
    YourCustomCell *cell = [self tableView:self.tableView cellForRowAtIndexPath:indexPathForYourCell];

    [cell.iz1TextField resignFirstResponder];
}

Answer 3

我的最终解决方案类似于@caglar 在这里建议的是我在里面编写的代码tableviewcontroller：

- (void)viewDidLoad
{
    [super viewDidLoad];

    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]
                                   initWithTarget:self
                                   action:@selector(dismissKeyboard)];
    [self.view addGestureRecognizer:tap];
}

-(void)dismissKeyboard
{
    [self.view endEditing:YES];
}
