While digging deep into the latest iPad SDK 3.2 beta 4, 9to5mac found two new touch commands for iPad/iPhone/iPod Touch. These new commands in the gestures folder of the iPhone 3.2 Beta 4 SDK.
In the gestures folder, you’ll see two new types of commands (3Tap.plist and LongPress.plist) that are certainly not implemented in the current 3.1 iPhone SDK.
Apple is likely allowing developers to use these new capabilities, found in the iPhone SDK, in the next versions of the OS. Apple may even allow developers to use them in the shipping version of the iPad.
