如何取消隐藏当前活动文本框的键盘？

发布于 2024-12-14 04:56:53 字数 268 浏览 1 评论 0原文

我在所有 UITextField 上都有一个链接到 EditingDidBegin 的 IBAction，那么为什么当点击 UITextField 时以下代码不起作用？

-(IBAction)keyboardShouldShow
{

[self becomeFirstResponder];

NSLog(@"Keyboard Showing");

}

另请记住，除非添加此代码，否则键盘不会显示，因为我的项目文件中有其他代码。

谢谢

I have an IBAction linked up to EditingDidBegin on all my UITextFields, so why isn't the following code working when the UITextFields are tapped on?

-(IBAction)keyboardShouldShow
{

[self becomeFirstResponder];

NSLog(@"Keyboard Showing");

}

Also bear in mind that the keyboard will not show unless this code is added because of other code I have in my project file.

Thanks

你自己不是你的文本字段。尝试将方法更改为此并将其重新链接到editingdidbegin。

-(IBAction)keyboardShouldShow:(UITextField*)sender
{

[sender becomeFirstResponder];

NSLog(@"Keyboard Showing");

}

HIH

your self is not your textfield.try to change the method to this and relink it to editingdidbegin.

-(IBAction)keyboardShouldShow:(UITextField*)sender
{

[sender becomeFirstResponder];

NSLog(@"Keyboard Showing");

}

因为 self 是您的视图控制器，而不是 UITextField。

使用 UITextFieldDelegate 方法：

- (void) textFieldDidBeginEditing:(UITextField *)textField {
   if ([textField isKindOfClass:[UITextField class]]) {
      [textField resignFirstResponder];
      NSLog(@"Keyboard Showing");
   }
}

如果您想使用自己的方法，请务必将 UITextField 作为参数传递。
将方法更改为类似：

-(IBAction)keyboardShouldShow:(id)sender {
     if ([sender isKindOfClass:[UITextField class]]) {
        [sender resignFirstResponder];
        NSLog(@"Keyboard Showing");
     }

}

Because self is your view controller, not the UITextField.

Use the UITextFieldDelegate method:

- (void) textFieldDidBeginEditing:(UITextField *)textField {
   if ([textField isKindOfClass:[UITextField class]]) {
      [textField resignFirstResponder];
      NSLog(@"Keyboard Showing");
   }
}

And if you want to use your own method, be sure to pass the UITextField as a parameter.
Change the method to something like:

-(IBAction)keyboardShouldShow:(id)sender {
     if ([sender isKindOfClass:[UITextField class]]) {
        [sender resignFirstResponder];
        NSLog(@"Keyboard Showing");
     }

}
