问题
In Xcode 4 when you would move a file, you could resolve the new location of the file by clicking a button in the right menu, and selecting the new location through Finder.
In Xcode 5, there is no button in the right menu and I haven't found any way to specify the new location of the file through right clicking the file, or the top menu bar options.
回答1:
- Right click the file in Xcode and select "Show File Inspector"
- In the file inspector click the little folder icon next to the file path.

This will open a file dialog allowing you to update the file path.
回答2:
Just delete the old one and add the moved one.
