i'm new in xcode and ios development. I try to create a radio app with rss. But when I changed the main view which contains the streaming then when I switch back the functions are not working in the main view. The second problem is when i try to go to the rss webview, then sometimes the app crashes. Here you can find two video what is the real problem: 1. if i go back from the rss view, there is a navigation view, with back button what i can't delete. And if i press the stop button it is started again the music. and the first music can't stop. 2. the rss detail view has an error but i still can't find what it is. http://devility.hu/first.mov http://devility.hu/second.mov source: http://devility.hu/help.zip Thank you, if anyone can helps in my problems !!!
