动态更改UIKeyboards返回键 [英] dynamically change UIKeyboards return key

问题描述

我有两个UITextfield，用户将他的名字输入第一个，然后发送电子邮件到第二个。我想知道如何更改UIKeyboards返回键，具体取决于名称文本字段是否有条目。

I have two UITextfield the user enters his name into the first and email into the second. I would like to know how to change the UIKeyboards return key depending if the name text field has an entry or not.

例如，如果nametextfield为空，那么我想要如果nametextfield中有一个条目，则UIkeyboard返回键为Next
else，然后当用户选择电子邮件文本字段时，我希望返回密钥提交。

For instance if nametextfield is empty then I would like the UIkeyboard return key to be Next else if the nametextfield has an entry in it then when the user selects the email text field I would like the return key to be submit.

这可能吗？如果是这样我将如何完成它？任何帮助将不胜感激。

Is this possible? if so how would I go about accomplishing it? any help would be appreciated.

推荐答案

您可以将返回键自定义为您可以在 UIReturnKeyType 枚举每个 UITextField 。

You can have return key customized to prefixed values that you can see in UIReturnKeyType enum for each UITextField.

textFieldName.returnKeyType = UIReturnKeyNext;
textFieldEmail.returnKeyType = UIReturnKeyDefault;

不确定这是否是你想要的。

Not sure if this is what you're looking for though.
