One of the best features of iOS 7 is the ability to have your iPhone, iPad or iPod Touch automatically update any apps that release new features, design changes or simply fixes a few bugs. This is not enabled by default, so you will need to manually turn on this feature to take advantage of background updating.
Imagine for a moment your finger is a magic wand. With certain movements and flicks, various actions will occur on-screen. The result can vary on the selection of operating systems available, however many employ similar methods if not identical ones when controlling an app.

Touchscreens were once limited to single touch commands. A press here and then a separate press elsewhere triggering events, however the best devices now offer multi-touch, which allows for simultaneous control of more than one area of the display.

Understanding the location and environment your app will be utilised in is extremely important when considering functionality.
