+[UIPasteboard _accessibilityUseQuickSpeakPasteBoard]: unrecognized selector sent to class

Question

I asked this question on Apple Dev forum, but still didn't get an answer.

We expirience 100% iOS 8 devices crash:

+[UIPasteboard _accessibilityUseQuickSpeakPasteBoard]: unrecognized selector sent to class

The stack trace is:

Despite the fact, TapJoy is captured in the stack trace, their FAQ says it is ocaisonally wrong and has nothing to do with TapJoy's code, but rather iOS 8 bug.

Is it correct?

What accessibility setting related to the crash?

Answer 1

This problem appears because TapJoy has used categories in static library (that's UIPasteboard_QSExtras) The solution is super simple, you need to notify linker about that

1) Click on the project
2) Click on the target
3) Open Build Settings tab
4) Search for Other Linker Flags

5) Double click on Other Linker Flags
6) Add -ObjC and -all_load flags
7)
Remove binary (delete from device/simulator),
Clean project (hitting cmd+shift+k) and
build again (hitting cmd+b).

You're ready to go!
