Increment and Decrement

Some assistive technologies change how we interact with elements on the screen. VoiceOver and Switch Control are two examples; we’ll cover more of how and why they do this in later chapters. But this means we need a new paradigm for controls that require more than a simple tap for activation. Sliders are a great example of this. UIKit’s UISlider control implements two functions, accessibilityIncrement() and accessibilityDecrement().
