There have been so many questions asked in here over the past few weeks/months that have clear answers right in Apple's documentation or sample code. 90% of programming for the average iPhone app involves simply piecing together existing API methods, so you need to be an expert at looking things up. Do you have a question about how to do something with a string? Search for the NSString class reference. Do you need to know how to change the background color of a label? Search for UILabel and look for anything that sounds like background color (backgroundColor maybe?). Apple's documentation is extremely clear and thorough. If you don't understand something it says, it probably means you need to spend more time learning Objective-C and/or object-oriented programming.
