Xcode 5将Xib升级到iOS 7

Question

So I am converting my pre-iOS 7 project. When I open it using Xcode 5 and go to individual xib file, it does not ask me to upgrade the xib. I do want to upgrade all xib files.

Should I need to be concerned with this at all?

Answer 1

Updating your .xib files to ios7 is fairly simple, all you have to do is go to your project navigator (blue page that should be at the top of your left sidebar), then click on your project, then click info at the top of the screen. Where you see iOS deployment target , change it to 7.0 (the path is Project manager> project> info> deployment target ):

now, you should be able to update your .xib files to ios7. Good luck!

Answer 2

You should not worry about the format of the nib/storyboard formats.

Xcode will upgrade their structure lazily once you actually open them in Xcode 5. This has nothing to do with supporting iOS7, as both upgraded nib files and Xcode 4.X nib files will all use the same iOS7 widgets when the project is compiled against the iOS7 SDK.
