Support armv6 and armv7 in the same ipa

Question

I have an XCode project configured like this:

• Project Format: XCode 3.1-compatible
• Architectures : Standard (armv6 armv7)
• Base SDK : Latest iOS (currently set to iOS 4.2)
• Build Active Architecture Only : UNCHECKED
• Valid Architecures: armv6 armv7

My question: Does the resulting binary (.ipa) have 2 executables in it - one for each architecture, or just some different object files for each architecture or is the split even finer grained than that?

Just curious. Thanks.

Answer 1

From what you described, the ipa should have a multi-architecture binary with both arm6 and arm7. You can check it with the file command in terminal. Inside of your app bundle is a executable that will have the same name as the app, myApp.app/myApp. Entering:

file myApp.app/myApp

in terminal will then print what it contains for you to double check. It should list the 2 architectures.
