Answer 1

套装创建一个符合UITextFieldDelegate协议的类，并使您的文本字段的委托成为此类的一个实例。实施方法：

- (BOOL)textFieldShouldReturn:(UITextField *)textField 

如下：

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

嗨，我发现出来，所以用文本框的一点是在viewDidLoad中添加此行：

textFieldOne.returnKeyType = UIReturnKeyDone; 
    textFieldCislo.delegate = self; 
textFieldTwo.returnKeyType = UIReturnKeyDone; 
    textFieldCislo.delegate = self; 
... 

而这种实现方法：

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

    if (theTextField == textFieldOne) { 
     [textFieldOne resignFirstResponder]; 
    } 
... 
}

    _theTextField.returnKeyType = UIReturnKeyDone; 
    [_theTextField setDelegate:self]; 

} 

// This part is more dynamic as it closes any text field when pressing return.

-(void)textFieldShouldReturn:(UITextField *)textField 
{ 
    [textField resignFirstResponder]; 
}

U可以通过点击视图中的任何地方使用这种方法来隐藏键盘

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