iphone utility application tutorial

I'm very new to iPhone development. I want to create a utility application much like the weather app (enter zip codes for cities to track the weather). The weather app allows users to scroll throug开发者_运维知识库h their favorite places. There's a flip side where you can manage your selections. I am looking for a tutorial on how to create a similar type app. Can anyone point me to a good tutorial for utility iphone apps please? I've been googling and can't find what I'm looking for. Thanks in advance.
