UIKeyboard next按钮不转到next UITextField

Question

我一直在尝试弄清楚如何让UIKeyboard上的next按钮加载下一个UITextField。我有两个单元格，名称和电子邮件，我想使用下一步按钮从名称转到电子邮件。

到目前为止，我已经添加了

//.h
 <UITextFieldDelegate>

然后，我这样做是为了尝试将用户从名称传递到电子邮件

//.m
- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    customerNameTextField.delegate = self;
    customerEmailTextField.delegate = self;
//...

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
    if (![customerNameTextField.text isEqualToString:@""]) {
        [customerNameTextField resignFirstResponder];
        [customerEmailTextField becomeFirstResponder];
    } else if (textField == customerEmailTextField) {
        // here you can define what happens
        // when user presses return on the email field
        // send request
    }
    return YES;
}

它进入第一个if语句，然后使用resignFirstResponder从屏幕上删除键盘，但不使用becomeFirstResponder加载新键盘。任何解决这个问题的帮助都会得到极大的欢迎。

这将从一个文本字段转到下一个textField...

-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
    if (textField == ist) {
        [second becomeFirstResponder];
    }
    else if (textField == second) {
        [third becomeFirstResponder];
    }

    else{
        [textField resignFirstResponder];
    }
    return YES;
}
