AAChartView don't appear in Today Extension

[Ragazzetto]

Hi guys. Everything works correctly in the iOS app but in the Today Extension I can't see anything ... I use almost the same code as the iOS app but I can't see anything, the view in the extension remains empty! Even if I use the example codes nothing changes ... Is there any limitation of use for extensions ? Thank you very much and excuse my terrible English.

Update I tried to use the library to populate a notification, but the result is the same , just a white view ...
