当没有文本字段来resignFirstResponder时如何解除键盘

Question

在下面的场景中，单击铅笔会使iz 1文本变为可编辑，方法是将其设为becomeFirstResponder并打开键盘，我希望在单击“空行”或iz2时关闭键盘。

我该怎么做？

我已尝试添加到cellView

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

但它无效

Answer 1

您可以使用以下方法隐藏键盘：

[self.view endEditing:YES];

修改

在您可以调用becomeFirstResponder的位置添加手势。

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

并在hide方法中删除它，

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

Answer 2

请致电：

-(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tableviewcontroller内写的代码：

- (void)viewDidLoad
{
    [super viewDidLoad];

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

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