Testing on an Actual Device

Although the iOS Simulator is a very handy tool that enables you to test your iPhone/iPad applications without needing an actual device, nothing beats testing on a real device. This is especially true when you are ready to roll out your application to the world — you must ensure that it works correctly on real devices. In addition, if your application requires access to hardware features on an iPhone, iPod touch, or iPad, such as the accelerometer, gyroscope, and GPS, you need to test it on a real device — the iPhone Simulator is simply not adequate.

This appendix walks through the steps you need to take to test your applications on a real device, be it the iPhone, iPod touch, or iPad. In addition, you will also learn how to prepare your application for submission to the App Store, as well as how to distribute your application using the Ad Hoc distribution method.
