The new look of iOS 7 is too different from previous versions. Is it possible to use old styled controls on iOS 7 on xCode 5.0?
回答1:
It's based on the SDK you're building against, so if you build against the iOS 6.X SDK instead of the iOS 7 SDK it should use the iOS 6.X look and feel. There's some information on how to do that here: Is it possible to install iOS 6 SDK on Xcode 5?
It's non-trivial though, and means you can't use any of the features introduced in the iOS 7 SDK. As long as you're comfortable with that then it's a good choice, the other thing to do would be to create your own variants of the iOS components with the same look that you want, which is a large amount of work.

Sure, but you need to copy the SDK from the previous xCode, I have both (xCode 4, xCode 5)
Copy this
/Applications/Xcode 4.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator6.1.sdk
to
/Applications/Xcode 5.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/
and copy this:
/Applications/Xcode 4.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk
to
/Applications/Xcode 5.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/
and, in your project change the "Base SDK" (on Build Settings) to iOS 6.1 instead of latest
