Apple don’t have any comprehensive pre-built GUI resources for app development, making it very hard to match the uniformed style of the iPhone or the iPad. You will need to create your own.
To help streamline your iPhone app design and development, we have put together a fairly comprehensive collection of iPhone & iPad GUI kits that will allow you to focus on developing rather than having to design everything from scratch.
Within this post you will find complete GUI kits and stencils, iPhone GUI elements and PSDs and finally a collection of the best icon-sets perfectly suited for the iPhone. (Some of the preview images are intentionally to large to show the as much of each GUI as possible).Complete iPhone & iPad GUI Kits

Design Stencil Kit version 1.0 is available for OmniGraffle, Visio (XML), Adobe Illustrator (PDF and SVG), and Adobe Photoshop (PNG). This 'Ultimate Stencil' for OmniGraffle contains backgrounds, title bars, buttons, selectors, and almost all iPhone UI elements. The text is fully editable on lists, title bars, buttons, and scroll wheels and the buttons can be resized horizontally by ungrouping, resizing the middle element, and then regrouping the elements back into a single button. This OmniGraffle stencil includes standard interface components for the iPhone 3G: buttons, fields, map elements, keyboards, icons… All of the components are on a transparent background and should re-size nicely. Design your application for iPhone, iPod touch and iPad devices with this exhaustive set of stencils. All stencils have been originally created by hand with native OmniGraffle shapes and groups and can be scaled, resized and exported to other vector formats in Graffle.This PSD was constructed using vectors, so it’s fully editable and scalable. The workable screen design is formatted to 768×1024 so anything you design in the Photoshop file can easily be brought over to the SDK.
