不调用textFieldShouldReturn [英] textFieldShouldReturn is not called

问题描述

当用户单击返回"按钮时，我想让键盘消失，有人告诉我使用

I want to make the keyboard disappear when the user clicks the "return" button, I was told to use

-(BOOL)textFieldShouldReturn:(UITextField *)textField {
    [tf resignFirstResponder];
    return YES;
}

但是当我单击返回"按钮时没有任何反应，甚至没有调用该方法.我正在

But nothing happens when I click the "return" button, the method isn't even being called. I am doing this in

@interface gameOverMenu : UIView

不在ViewController中.我也不使用界面生成器.我该怎么办?

not in the ViewController. I also don't use interface builder. What should I do?

推荐答案

您需要确保实现UITextFieldDelegate并将UITextField委托设置为self.在您的.h文件中:

You need to make sure you implement the UITextFieldDelegate and set your UITextField delegate to self. In your .h file:

@interface gameOverMenu : UIView <UITextFieldDelegate>

.m文件中的某处(viewDidLoad:也许):

And somewhere in your .m file (viewDidLoad: maybe):

self.yourTextField.delegate = self;

现在，应调用-(BOOL)textFieldShouldReturn:(UITextField *)textField方法.

Now your -(BOOL)textFieldShouldReturn:(UITextField *)textField method should be called.
