Bill Weinman shows you how to harness system resources in your iOS projects, including the camera, Address Book, location services, URL schemes, geolocation, and more! Learn to provide translated text and other data when your app is used in international locales, access photos and video in the camera roll, and use URL schemes to launch browser and email windows. You can even use URL schemes to communicate between apps. Bill also shows how to read information from the Address Book, integrate your app with social media, and interpret motion data to discover the orientation of an iPhone or iPad in the hands of the user.
