推荐答案

只需清除字段resignFirstResponder（如果要隐藏键盘）并返回NO / false

Just clear the field, resignFirstResponder (if you want to hide keyboard) and return NO/false

Note: set Attributes inspector property of UITextField 

清除按钮 - >编辑时出现

so it will display 'X' button while editing in textfield.

// Objective-C

-(BOOL)textFieldShouldClear:(UITextField *)textField
{
    textField.text = @"";
    [textField resignFirstResponder];
    return NO;
}

// Swift

func textFieldShouldClear(textField: UITextField) -> Bool {
    textField.text = ""
    textField.resignFirstResponder()
    return false
}
