MKStoreKit doesn't works on iPod 2

I'm trying to integrate MKStoreKit into my game, but when [MKStoreManager sharedManager] called, app crashes on ipod 2 with error:

dyld: lazy symbol binding failed: Symbol not found: _objc_retain Referenced from: /var/mobile/Applications/2EA46519-12C1-4ED8-B19B-ED4AFA178F81/uni.app/uni Expected in: /usr/lib/libobjc.A.dylib

//latest MKStOreKit, Xcode 4.2.1, on other devices no error occured

Solution

  • That sounds like an ARC issue to me.

    What iOS version is running on the iPod? ARC will work on iOS 4 and above.

    Try adding -fobjc-arc to the "Other Linker Flags" build setting for your project.
