Error updating from 2.X to 3.X

[deneb42]

Hello, I'm upgrading from 2.5 to 3.1.3, but I am experiencing some issue when calling [WeiboSDK registerApp:myAppId];

Here is the error message :

-[NSConcreteMutableData wbsdk_base64EncodedString]: unrecognized selector sent to instance 0x17045ad30
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSConcreteMutableData wbsdk_base64EncodedString]: unrecognized selector sent to instance 0x17045ad30'

And here's the callstack:

+[WeiboSDK registerAppWithAppKey:](self=WeiboSDK, _cmd=<unavailable>, appKey=<unavailable>) + 140 at WeiboSDK.m:1101 [opt]

I tried the sample app which is working, and spent the day comparing the two setups to locate a possible mistake, but with no luck. Could you help me on that or provide me a distribution with the symbols to help be debug the issue ?

Thanks in advance, Benjamin

Note I'm building in static. This is fixed when -force_load the libWeiboSDK.a
