Can I get an armv7 only version of the library? This way I can directly use the PDFNet library for armv7 only, without having to do the same for our app project itself.
You can extract an armv7 only version of libPDFNet.a with the following terminal command:
xcrun -sdk iphoneos lipo libPDFNet.a -extract armv7 -o libPDFNet-armv7only.a
Note that you will also have to use the linker flag -allow_sub_type_mismatches or you will probably get linker errors.
