如何在用户输入上设置UITextView的光标位置？ [英] How to set cursor position for UITextView on user input?

问题描述

我正在为这个问题寻找一个简单的答案...

我有一个 UITextView ，其中用户可以开始输入并单击DONE并辞职。

当想要再次编辑它时，我想让光标（闪烁的线）位于 textView ，而不是在textView的结尾。 （像占位符一样）

我尝试了 setSelectedRange > NSMakeRange（0,0）在 textViewDidBeginEditing ，但它不工作。

更多信息：

可以看到..当用户点击 textView 的光标出现在用户点击 textView

我想让它始终在起始位置闪烁 textViewDidBeginEditing 。

<因此我最后在 UITextView 中添加了一个UILabel，它作为textView的占位符。点击UILabel会将动作发送到textView和 becomeFirstResponder 。一旦您开始输入，请将标签隐藏。

I am looking for a simple answer for this problem...

I have a UITextView in which the user can start typing and click on DONE and resign the keyboard.

When the wants to edit it again, I want the cursor (the blinking line) to be at the first position of the textView, not at the end of textView. (act like a placeholder)

I tried setSelectedRange with NSMakeRange(0,0) on textViewDidBeginEditing, but it does not work.

More Info:

It can be seen that.. when the user taps on the textView the cursor comes up at the position where the user taps on the textView.

I want it to always blink at starting position when textViewDidBeginEditing.

解决方案

So I ended up adding a UILabel over the UITextView which acts as a placeholder for the textView. Tapping on the UILabel would send the action down to the textView and becomeFirstResponder. Once you start typing, make the label hidden.
