Why am i still getting Linker errors after commenting out function declarations?

I have declared some methods in my header file, commented out the ones that i have not implemented yet,
but when i try to build i am still getting Linker errors. Does Xcode not refresh my header file, or is something else wrong? (sorry for the links, I could not post working links for some dictatorial reason)

Screenshots to explain my problem, commented out function declarations:

and Linker errors during build:

Argh. Never mind, i found out. Somehow, X-code does not refresh a file when there are other, possibly super trivial errors in that file, that are NOT yet listed somehow. man, X-code could really do better for a full fledged IDE :frowning:
