问题
I've imported another programmer's project into Xcode and get the error "UIKit/UIKit.h file not found." I tried right clicking the Frameworks folder but didn't see a way to add it. How can I add the UIKit to this project?
回答1:
Navigate to the target and go to Build Phases and add UIKit to Link Binary With Libraries.
From the Comments to this post:
MonkeyBusiness: Sorry to waste your time. I had set the project up as MacOS rather than iOS. I'm new to Apple and iOS as you can see.
回答2:
Check that you are using a iOS project and not a Mac OSX one - UIKit is only for the iPhone/iPad
