App won't run on iOS 4.2, Architecture issue

Question

I have an app that I developed in Xcode 4.3.2. I am using the base SDK as 5.1. The app installs fine in iOS 5.0 and above. But I need to support iOS 4.0 and above.

The compiler I am using is Apple LLVM compiler 3.1.

I have added both armv6 and armv7 to the architectures (See attached image))

I created an AdHoc build. When I sync it using iTunes, it syncs fine with iOS 5.0 and above, I have not tested in iOS 4.3, but it does not install in iOS 4.2.1. It gives this error:

The app "App Name" could not be installed on the iPod "iPod Name" because it is not compatible with this iPod.

Any thoughts?

Thanks.

Answer 1

You should remove the armv7 from the Required device capabilities in the info.plist.

This restricts the app being installed on device that do not have an ARMV7 processor, like older iPad touches and iPhones.
