iOS Dev Using Objective-C, Part 3: Gestures

with expert David Solberg

In this course we look at the basic UITouch object that represents a touch, then use its properties and methods to manipulate the interface. Then gesture recognizers are introduced as Apple's solution to managing multiple types of interaction in the same view or views. Next we add zooming and rotating to the collection of gesture recognizers that will work on a view. Then we further refine our code to center all events and changes based on the centroid of the user interaction.
