UITextField 文本在每隔一个击键时消失 [英] UITextField text disappears on every other keystroke

问题描述

这是现象的视频:http://youtu.be/c0TP8YVF9TE

如视频所示，exampleTextView.text 中的值没有丢失.它只是隐藏了所有其他按键.

As the video shows, the value in exampleTextView.text is not lost. Its just hidden every other keystroke.

尝试的解决方案:我不会在程序期间将 exampleTextView.text 值设置为某些值，除非在按下返回键之后(并且注释该行没有任何改变).

Solutions tried: I do not set the exampleTextView.text value to something during the program, except after the return key is pressed (and commenting that line out changes nothing).

我已经设置:

self.exampleTextView.clearsOnBeginEditing=NO;
self.exampleTextView.clearsContextBeforeDrawing=NO;
self.exampleTextView.clearsOnInsertion=NO;

这是我的代码:https://gist.github.com/andrewschreiber/6970283

推荐答案

我遇到了几乎同样的问题.有时文字会消失.

I had almost the same problem. Sometimes the text was disappearing.

我在xib文件中改变了UITextField在视图层次结构中的位置后解决了.

I solved it after changing the position of the UITextField in the view hierarchy in the xib file.
