Hi Guys, I am new in iPhone development. But I have 18 years expirience in Win programming. Ah, guess, it is the root of the problem ;-) I want to switch between two views. I take this idea from "Metronome" sample by the Apple. As I see, I do the same, but see just black screen. I attached my example. Could anybody say what I do wrong or what I did not? Thank you for your help!
