推荐答案
所以我弄清楚了。 IOS6 SDK中的变化是,如果以编程方式更改文本字段的文本,则不会发送通知。我在所有这些视图上都有一个自定义键盘。当我点击一个键时,它会通过添加我键入的内容来更改文本字段文本值。在ios 5中,它会发送通知textdidchange,但不会在ios6中发送。
so I figured it out. What changed in IOS6 SDK is that if you change the text of textfield programmatically, it doesn't send a notification. I have a custom keyboard on all of those views. when I tap on a key, it changes the text field text value by adding whatever I typed in. In ios 5 it would send a notification "textdidchange", but not in ios6.
