• Tapping

• Gesture recognitions (swiping in any direction, pinching, rotating)

• Moving sprites using the accelerometer

Let's discuss each of the preceding controls in detail and also how we can implement them in our game.

We have four override methods for handling touch events with a UIResponder class, which is part of UIKit provided by Apple. Let's learn about them:

• func touchesBegan(touches:Set<NSObject>, withEvent event:UIEvent): This method is called whenever a user touches the view/window

• func touchesMoved(touches:Set<NSObject>, withEvent event:UIEvent): This method is called whenever a user moves his finger on the view/window

• func...
