UISlider compatibility

2.0.0 Upgrade Notes

If you were using previous versions of TGPControls, you may need to address the following:

• search and replace instances of thumbColor by thumbTintColor. It is the same property adopting UISlider naming convention.
• tintColor now affects the right side of the slider (the opposite of what it used to be). Again, this is adopting UISlider behavior convention.
• 2 new properties are available: minimumTrackTintColor and maximumTrackTintColor, also adopting UISlider behavior convention.

Cosmetic changes

• The ComponentStyleIOS thumb responds to thumbTintColor. It has be reduced ever so slightly to match iOS 9 appearance.
• The ComponentStyleIOS track matches the iOS track colors exactly.
• The track can be drawn at any size and maintain its color, clipping and integrity, even when the thumb is invisible.
• ticks color is controlled by tintColor, and is not overruled by minimumTrackTintColor.

UIControlEvents, Fill with alpha

Fixes #13, @hebertialmeida's #15, #16 .

• Support for UIControlEvents, fired in the same order as with UISlider
  Add listener:

  self.discreteSlider.addTarget(self, action: "touchUpInside:event:", forControlEvents: .TouchUpInside)
  

  Listen:

  func touchUpInside(sender: UIControl, event:UIEvent) {
      print("touchUpInside")
  }
  

• Use CGContextSetFillColorWithColor to support alpha channel

Production release

Animated labels and discrete slider with customizable ticks, track, thumb, color, images. Use Core Animation (CALayer) for smooth animation. Very responsive, elegant.

Most of all, a snap to drop as a replacement of UISlider.
