Unknown class RNEmailField in Interface Builder file

Question

I have my app published on the app store, say version 1.2.

I'm developing version 1.3, if the current live application (taken from the app store, 1.2) is installed on my device and I build & run the project in Xcode on the very same device it crashes with:

2013-06-19 05:52:36.381 MyApp[12381:907] Unknown class RNEmailField in Interface Builder file.
2013-06-19 05:52:36.393 MyApp[12381:907] Unknown class RNAvatarImageView in Interface Builder file.

I removed every single instance of this plugin (installed via Pod) and it does not appear anywhere in the code now (I don't want it anymore).

If I uninstall the 1.2 live application from the phone, build & run 1.3 the application starts correctly. I made sure all the targets are ok, cleaned and cleaned build folder multiple times to no avail.

My fear is that once I release the upgrade the app will crash right at the start until a user uninstalls and reinstalls.

I did read all the other threads about this problem but nothing solves it beside uninstall the previous app version.

What should I do?

Answer 1

如果已删除此库，则选择“电子邮件textfeild”，转到“身份资源管理器”，并将类设为UITextfeild ..，与Imageview相同。

将MainStoryboard_iPhone重命名为Main_iPhone，一切恢复正常。
