Apple iOS iPhone Operating System, iOS is the operating system that was developed specifically for the iPhone,
but now it is also used to run applications on other Apple devices
including the iPad, iPod Touch, and Apple TV. There are many
similarities between iOS and Mac OS X though the former was developed
specifically with mobile devices in mind (Apple Developer, 2010).
Apple’s
iphone developer site dedicates an entire section to the iOS Dev
Center. As mentioned in Chapter 1, the iOS software development kit
(SDK) contains tools needed to create and test mobile applications
within an iOS environment. These X code tools also allow developers to
test their code within an iOS Simulator to ensure the app is functioning
properly.
