Question

Please help me from the below error.

I am working on graphs using 3rd party framework (libIPhonecharting), every thing works fine in simulator, but when I am trying to build .app file to install in IPAD Device I get the below error message.

ignoring file /Users/xyz/Desktop/xyzIPAD/library/4.0/Release-iphoneos/libIPhoneCharting.a, file was built for archive which is not the architecture being linked (armv6)

Answer 1

Here's how I got this problem:

I added a .h, .m and NIB from another project by dragging them onto my project navigator. Xcode didn't add them to the Build Phases properly.

My solution for this problem:

• Go to the Target in the navigator menu
• Click on the "Build Phases" tab
• Add the .m file to "Compile Sources" (either drag it across, or use the + button)
• Add the .xib to "Copy bundle resources"
• Clean and build

It works for me thanks a lot to you
