Character not found: _objc_retainAutoreleasedReturnValue works with compiled ARC code on iOS 4.3

My code is built with the base SDK 5.1 and deployment 4.0 and built using ARC.

I had no problems earlier when running on a test device 4.3, however it just crashed for the first time.

Any idea how to fix this?

Where did the crash happen? I had the same thing that suddenly started with a new compiler.

For me, I had code inside the override +(void) loadthat seemed to be called before the arclite code was correctly linked. I'm not sure if this is possible, but moving the same code in +(void) initializeworks fine.

@Paul de Lange, .

100%, , Xcode 4.4, ARC libarclite_xxx.a( iOS4) + (void) ( ).

Xcode <= 4.3:

  • LINKING libarclite_xxx.a
  • +
  • +
  • int main()
  • class + initialize

Xcode >= 4.4:

  • +
  • LINKING libarclite_xxx.a
  • +
  • int main()
  • class + initialize

My application crashed on its first launch due to the addition of @autoreleasepool directly in the class + load, and, moving its implementation to either class + initialize or class category + load, everything went fine.
