IOS

iOS 7 running on an iPhone 5s.

iOS is Apple's mobile operating system developed originally for the iPhone, and later deployed on the iPod Touch and iPad as well. It is derived from Mac OS X, with which it shares the Darwin foundation, and is therefore a Unix-like operating system by nature. In iOS, there are four abstraction layers: the Core OS layer, the Core Services layer, the Media layer, and the Cocoa Touch layer. The operating system uses roughly 500 megabytes of the device's storage.

Ace Attorney series on iOS

To date, only Phoenix Wright: Ace Attorney, the first game in the Ace Attorney series, is available (with the Nintendo DS sprites) in the App Store worldwide. In Japan, however, Phoenix Wright: Ace Attorney: Justice For All and Phoenix Wright: Ace Attorney: Trials and Tribulations, the next two games in the series, are also available.

Gyakuten Saiban 123HD ~Naruhodo Ryuichi-Hen, a re-release of the first three games in the series using "HD sprites" (modified from character and background art), was announced for iOS and released in Japan on Feb. 7, 2012, with an English localization titled "Phoenix Wright: Ace Attorney Trilogy HD" being released on May 30, 2013. The first two cases of the first game are free, while the remaining cases and games are available as in-app purchases.

Controls

Ace Attorney games on the iOS use a simple control scheme that utilize touch screen controls in a similar way to their DS counterparts. However, a few things have been changed. For example, instead of using the DS microphone to "blow away" fingerprint powder, players instead swipe the screen to remove the powder.
