i'm new ios development, , i've seen, pdfs can tricky, decider search library or opensource project begin with.

as said, i'm new ios, so: can give me pointer should start modify app? or maybe point me tutorials on this, or similar question? don't need copy paste code (but feel free post it, if must, :)), gidance start.
