================================

#How To Use:

You can add this UI element programmatically or with Interface Builder.

I show how to add this in Interface Builder in steps 1 and 2.

1. Drag a UISlider from the Object Library (bottom part of Utilities panel). 

2. Change class from default to custom class MTZTiltReflectionSlider. 

3. Add the CoreMotion Framework to your project 

4. Be sure to #import "MTZTiltReflectionSlider.h" in your UIViewController subclass

5. Set the size of the knob

   Small: 32px (MTZTiltReflectionSliderSizeSmall)

   Regular: 48px (MTZTiltReflectionSliderSizeRegular)

    [_mySlider setSize:MTZTiltReflectionSliderSizeSmall]
   

   If no size is set, it defaults to regular size (48px)

6. Tell the slider to start motion updates when needed and stop when not needed

   In your UIViewController subclass:

    - (void)viewWillAppear:(BOOL)animated
    {
    	[_mySlider startMotionDetection];
    }
   
    - (void)viewWillDisappear:(BOOL)animated
    {
    	[_mySlider stopMotionDetection];
    }
