如何在UITextField上自动打开键盘？ [英] How to open the keyboard automatically on UITextField?

问题描述

我有一个非常简单的表格，当它打开一个单元格时，它会打开一个带有一个UITextfield的新视图。我想要的是键盘将自动打开，用户不必触摸UITextfield。

I have a very simple table and when tocuh a cell it opens a new view with one UITextfield. All I want is that the keyboard will automatically opens, without the user have to touch the UITextfield.

这一切都在Interface Builder中完成，所以我不知道我是怎么做的这个。我想我需要在某个时候设置焦点？

Its all done in Interface Builder, so I am not sure how I do this. I guess I need to set the focus at some point ?

谢谢

推荐答案

要使键盘立即显示，您需要使用以下行将文本字段设置为第一响应者：

To cause the keyboard to show up immediately you'll need to set the text field as the first responder using the following line:

[textField becomeFirstResponder];

您可能希望将其放在 viewDidAppear中：方法。

You may want to place this in the viewDidAppear: method.
