How to set labels at dictionary in Xcode?

What do you mean with set labels at dictionary?
Do you mean, setting an string as key for values in an dictionary? Or setting actual NSLabel's text to an value from an dictionary?

 

Wow. You really do think that people responding on MacRumors can read your mind? Next time, just post "I need help", better if you don't add things that are just misleading people, since your problem has nothing to do with labels or dictionaries.

I'd check if the files in question are actually copied into your compiled project, and if they are, i would search for "could not open file" in the source code, set a breakpoint around there, and see what happens.
