Has any one had the following issues while using iPhone OS 3.0 and iOS 4.0.
I am getting the error while adding flurry analytics.
NSConcreteGlobalBlock and UIBackgroundTaskInvalid runtime error occur under 3.x.
Error description:
Symbol not found: __NSConcreteGlobalBlock
Expected in: /usr/lib/libSystem.B.dylib
Also UIBackgroundTaskInvalid
this link says to add extra linker flag,, can any one help me in knowing how to add multiple linker flag in the xcode.
The linker flags are:
* weak_framework UIKit
* weak_library /usr/lib/libSystem.B.dylib
How to add these multiple linker flags to the xCode.
What is the seperator between multiple flags, do I need to have.
Found the solution
this doc gives the clear explaination of weak linking
