When click on your project in the project explorer, for each target, select that target. Then in the build phase, in the link with binary libraries, check your framework links.
If you have simple problem, you can remove and add the libraries again.
If the library is not built for arm7s, then goto target's archtecture, in the valid architectures, set it armv7 only. See if this remove the problem. if it is, then the frameworks needs to be build for armv7s.
