Visit these web sites for helpful coding advice:
CocoaHeads: This is the site of a group dedicated to peer support and promotion of Cocoa. It focuses on local groups with regular meetings where Cocoa developers can get together, help each other out, and even socialize a bit. There’s nothing better than knowing a real person who can assist you, so if there’s a CocoaHeads group in your area, check it out. If there’s not, why not start one?
NSCoder Night: NSCoder Nightsare weekly, organized meetings where Cocoa programmers get together to code and socialize. Like CocoaHeads meetings, NSCoder Nights are independently organized local events.
Stack Overflow: This is a community Q&A site targeted at programmers. Many experienced iOS programmers hang out here and answer questions.
