[NSTaggedPointerString objectAtIndex:]: unrecognized selector sent to instance
提问by Webdevotion
I have a problem with everyUITextfield in my app. Whenever an instance of UITextfield becomes first responder, my app crashes with the following error message.
我的应用程序中的每个UITextfield都有问题。每当 UITextfield 的实例成为第一响应者时，我的应用程序就会崩溃并显示以下错误消息。
Some details about the app:
有关该应用程序的一些详细信息：
- multi language support
- using storyboards
- My app used
user defined runtime attributeswhich I'm trying to get rid of ( legacy of using the PixateFreestyle SDK to style the UI ), but there are still some of those attributes in the storyboards left. - Testing on real devices
- I have set a symbolic breakpoint on
[NSTaggedPointerString objectAtIndex:]but it does not seem to catch the error before the app itself crashes - iOS 8 SDK / Swift / Xcode 7.1 ( happened on Xcode 7 too )
- 多语言支持
- 使用故事板
- 我的应用程序使用
user defined runtime attributes了我试图摆脱的（使用 PixateFreestyle SDK 设置 UI 样式的遗留问题），但故事板中仍然存在一些这些属性。 - 在真实设备上测试
- 我已经设置了一个符号断点，
[NSTaggedPointerString objectAtIndex:]但它似乎没有在应用程序本身崩溃之前捕获错误 - iOS 8 SDK / Swift / Xcode 7.1（也发生在 Xcode 7 上）

回答by Husam
You should set an array to "AppleLanguages"not string
您应该将数组设置"AppleLanguages"为非字符串
In other words :
换句话说 ：
Replace this
替换这个
NSUserDefaults.standardUserDefaults().setObject( "en-BE", forKey: "AppleLanguages" )
With this :
有了这个 ：
NSUserDefaults.standardUserDefaults().setObject( ["en-BE"], forKey: "AppleLanguages" )

After I removed this piece of code in the app, the bug was fixed.
在应用程序中删除这段代码后，该错误已修复。
NSUserDefaults.standardUserDefaults().removeObjectForKey("AppleLanguages")
NSUserDefaults.standardUserDefaults().setObject( "en-BE", forKey: "AppleLanguages" )
if( NSUserDefaults.standardUserDefaults().synchronize() ){
// ...
}
