objective c - Zbar SDK is not working in iOS6

Question

I was using ZBar for scanning in iOS5 and it was working well.

Now after updating to iOS6, its not working. It shows a following error.

    ld: file is universal (3 slices) but does not contain a(n) armv7s slice: /Users/mac4/Desktop/my desktop/My app/MyApp name 20:09:12  /MyApp name/ZBarSDK/libzbar.a for architecture armv7s
clang: error: linker command failed with exit code 1 (use -v to see invocation)

What is wrong in my side?

Answer 1

In Xcode, go to the settings of your target, change 'Valid Architectures'

from

armv7,armv7s

to

armv7

This change means your app will not take advantage of possible optimizations the new iPhone5 processor has, but you don't have to wait for 3rd party libraries to upgrade or mess with a hex editor.
