Based on my personal experience (I was not initially familiar with Objective-C or even C, in this respect - my programmer was PHP Javascript and shell scripts), I found that a number of books are more useful than any website - maybe , this is the answer you are looking for:
- "Programming in Objective-C 2.0" by Stephen Cochan (for learning the language. Until I had this book, they continued to confuse me with most Objective-C)
- "iPhone SKD" published by O'Reilly (in order to understand how to do this)
- Developer Documentation (part of Xcode - try [double-clicking Alt] on a word in Xcode)
- google search
- stackoverflow.com
- sometimes even the header files of the framework (in Xcode) of the libraries you use
Using the first three tools, I found that I could understand most of what I needed to know. When I was at a loss after checking these sources and searching on Google, this forum was indispensable for learning what I needed.
