I am working on xcode 6 and I create a static library, the application working fine on ios 8 but I got this problem Undefined symbols for architecture armv7 when I try to lunch the app on ios 7.

Can someone tell me why please?

    It's probably because you're trying to run on a iPhone 4 or 5 that are armv7 (it does not depends on the iOS version). To run on those devices, your static library has to be compiled for both architecture. – KIDdAe May 04 '15 at 12:10

Select project target > Build Settings > Search for "VALID_ARCHS"

Check whether you've added armv7, if not, add it.

Further reading about "VALID_ARCHS", you can refer to THIS ANSWER.
