阅读更多关于 Are protocol-relative URLs relative URLs?

问题 So consider a protocol-relative URL like so; //www.example.com/file.jpg The idea I've had in my head for as long as I can remember is that protocol-relative URLs are in fact absolute URLs. They behave exactly like absolute URLs, and never do they work like relative URLs.

问题 I am asking because I am working on a project for school. Yes this is homework. But, I'm trying to understand a little bit more, though.

阅读更多关于 Adding files in Xcode 4: ensure the path is relative to the project/how to change path?

问题 In Xcode 4, I can't add files/resources to my project without having the Relative-to-Group path end up something like: ../../workspace/Project/Resources/thing.png Ideally I would have Resources/thing.png .
