如何在Xcode 4.4中将部署目标从iOS 5.1更改为4.2

Question

I am trying to change the deployment target from 5.1 to 4.2 in Xcode 4.4 and it's not working

• I downloaded debugging support for 4.1-4.2
• I set Architecture to armv6 armv7
• I set in plist armv6 armv7
• I don't use storyboards

Answer 1

It's a known bug . XCode 4.4 doesn't let you target armv6 architecture. You'll have to downgrade to Xcode 4.3.3 to do this (learned it the hard way :-/). You'll have to download 4.3.3 from the Apple dev website.

Also, make sure not to run both 4.4 and 4.3.3 at once. My mac was semi frozen for an hour until I managed to force kill these two processes.

Update: This bug has been fixed in the newer versions of the XCode.

Answer 2

In case anyone is still affected by this issue, it appears to have been fixed. In Xcode 4.4.1 I do not have this problem. (Specifically, when I set architecture to armv6 armv7, I am able to build for an iPhone 3G running 4.2 - I have not tried other combinations.)
