编译remail-iphone项目报错 Undefined symbols for architecture armv7 ImapFolderWorker fetchFrom

现象：
Undefined symbols for architecture armv7:
"_IfTrue_RaiseException", referenced from:
-[ImapFolderWorker fetchFrom:to:seqDelta:syncingNew:progressOffset:progressTotal:alreadySynced:] in ImapFolderWorker.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我的解决方法：屏蔽类ImapFolderWorker 的代码行，共两行：IfTrue_RaiseException(err != 0, CTUnknownError, [NSString stringWithFormat:@"Error number: %i", err]);
但这样做只是可以保证编译通过，可以正常run，登录邮箱账号，但不能收邮件，彻底的解决方法：使用与remail相兼容的MailCore版本，见作者原话，如下

原因：见作者在google group 的解释

Hi!



I'm the author of MailCore. I recently made some changes that broke compatibility with Remail, sorry about that :(
Unfortunately it was something I had to do to improve the MailCore API.



For now use this revision of Mailcore to build against Remail, it should still work: https://github.com/mronge/MailCore/commit/7c13b7b9518e0bc2cdd86e092245e0e05afa0239



Eventually I'd like to get Remail working with the latest but I have not had a chance to do so.

解决：编译错误及不能收邮件的问题： https://groups.google.com/forum/?fromgroups=#!topic/remail-iphone/SmnEeX9N6As 使用修改前的MailCore版本

大功告成，可以下载邮件了，见截图。
