Can anyone suggest a good starting book for learning the basics of IOS 4 for developing apps for the Iphone? I have been using Visual Studio for developing apps for the PC using C++ and C# for 15 years and I find the IOS platform completely foreign to me. Actually, I feel stupid as I cannot seem to get the hang of developing views. The language seems very obtuse to me and I need to wrap my mind around the whole concept of IOS development. I have been using the book by the Big Nerd Ranch and also Fundamentals of IPhone Development by Matt Neuberg and I find that using their examples sometimes leads to compiler errors that I cannot correct. Any advice is appreciated.
