辞职第一响应者仅在一个文本字段中不起作用

希望有人能在这里帮助我。我有一个带有 3 个文本字段的 UIView。我希望键盘上的“返回”键让第一个响应者辞职，无论用户光标位于哪个文本字段中。我的代码适用于 3 个文本字段中的 2 个，但始终（一如既往）它拒绝首先辞职来自第三个文本字段的响应者，我不知道为什么（文本字段是相同的。不起作用的字段是第三个字段...

这是代码（如果有帮助的话）

- (BOOL)textFieldShouldReturn:(UITextField *)textField {

    [firstTextField resignFirstResponder];
    [secondTextField resignFirstResponder];
    [thirdTextField resignFirstResponder];

    return YES;
}

中的属性声明

@property (weak, nonatomic) IBOutlet UITextField *firstTimeTextField;
@property (weak, nonatomic) IBOutlet UITextField *secondTextField;
@property (weak, nonatomic) IBOutlet UITextField *thirdTextField;

这是 H It 看起来很简单，所以我想知道是否应该进行某种错误检查来确定这里发生的情况。

该文件也被声明为 UITextFieldDelegate...

感谢您的时间和帮助！

Hopefully somebody can help me out here. I have a UIView with 3 text fields. I want the "return" key from the keyboard to resign the first responder, regardless of which text field the users curser is in. My code works for 2 of the 3 text fields, but consistently (as in always) it refuses to resign first responder from the 3rd text field, and I don't know why (the text fields are identical. The field that does not work is the 3rd field...

Here is the code if it helps

- (BOOL)textFieldShouldReturn:(UITextField *)textField {

    [firstTextField resignFirstResponder];
    [secondTextField resignFirstResponder];
    [thirdTextField resignFirstResponder];

    return YES;
}

Here is the property declaration in the H

@property (weak, nonatomic) IBOutlet UITextField *firstTimeTextField;
@property (weak, nonatomic) IBOutlet UITextField *secondTextField;
@property (weak, nonatomic) IBOutlet UITextField *thirdTextField;

It seems pretty straight forward, so I'm wondering if there is some kind of error checking that I should be doing to determine whats happening here.

The file is declared as a UITextFieldDelegate as well...

Thanks for the time and the assistance!
