RxSplitSlider
Reactive extension for SplitSlider.
Customizable two way slider split in the middle. Left and right parts are independent, each can have different min, max, step, colors, etc.
Usage
Simply add as custom view to storyboard or create programatically. Don't forget to import SplitSlider
as well.
let slider = SplitSlider()
Generic slider properties (affects both parts):
// Minimal slider value.
slider.min = 0
// Maximal slider value.
slider.max = 100
// Step value of the slider.
slider.step = 5
// Font of the value labels.
slider.labelFont = UIFont.systemFont(ofSize: 10)
// Font color of the value labels.
slider.labelTextColor = UIColor.black
// Size of the slider's thumb.
slider.thumbSize = 20
// Color of the thumb.
slider.thumbColor = UIColor.darkGray
// Track height.
slider.trackHeight = 0
// Track color.
slider.trackColor = = UIColor.lightGray
// Color of selected part of the track.
slider.trackHighlightColor = UIColor.gray
// Determines if thumb should be snapped to the closest step after the move.
slider.snapToStep = true
All above properties would affect both portions of the slider but can be set individually through either slider.left
or slider.right
portion.
Observing changes
// Slider portion selected - called when user selects (holds) portion of the slider. Return `nil` when no portion is being selected.

}).disposed(by: disposeBag)
