UITextField 触摸时崩溃 -- iOS8

Question

我的项目在 iOS7 上运行良好。但是当我在 iOs8 上尝试时，UITextFields 使应用程序崩溃。我将一个全新的 UITextField 添加到我的故事板之一并触摸新创建的 UITextField（没有代表附加到文本字段），应用程序再次崩溃。我花了整整几天的时间，非常感谢你的帮助。

Answer 1

出于某种原因 Sergiy Salyuk 没有 post 回答，但他的评论有效。

问题在于用 NSUserDefaults

替换 "AppleLanguages" 中的初始语言数组

它节省了很多时间，因为问题只出现在测试设备上，而在其他国家，我不知道如何找出崩溃与此跟踪和 "AppleLanguages" 在 NSUserDefaults.

再一次谢谢你 Sergiy。
