问题
Our build server was recently updated to use Xcode 5's xcodebuild. We've installed the iphoneos6.1 so that we can still use iPhone SDK 6.1 for some legacy projects that do not yet support iOS7. However, when we use xcodebuild to build these projects using -sdk iphoneos6.1, we still see problems with UIViewController's contents being laid out underneath navigation bars and tab bars.
Is there some way to build these projects that were developed with Xcode 4.6.3/base sdk iOS 6.1 using Xcode 5's xcodebuild, but preserving the views as they were laid out in the storyboard developed using Xcode 4.6.3? I took a look at the man page for ibtool, but I'm not seeing any option related to choosing a target SDK, or anything else that seems relevant to the "extends edges" problem I noted above.
Note that we haven't updated the storyboard using Xcode 5 - the project is continuing to be developed in Xcode 4.6.3, and only touches the Xcode 5 toolchain when our build server clones the project's git repo and builds using xcodebuild.
回答1:
Yes. On the Storyboard, go to the Interface Build Document section and there are two selection items. One for Builds For and one for View As. You can select anything from 7.0 down to 4.3 for the Builds For and you can select '7.0 and later' or '6.1 and earlier'.

While it isn't exactly what you are looking for, you can keep both Xcode 4 and Xcode 5 in the same build environment and control which xcodebuild is run by using an environment variable (see man page for xcrun. We have just set this up on one of our build servers. In your build definition, just set the following environment variable:
DEVELOPER_DIR=<path to Xcode 4.app>/Contents/Developer
For us, it ended up as:
DEVELOPER_DIR=/Applications/Xcode-4.app/Contents/Developer
This overrides the xcode-select setting and allows you to use the correct Xcode environment. Again, this depends on the ability of your build system to set environment variables, plus having both versions of Xcode installed. You can download older versions of code at Downloads for Apple Developers
