A custom reusable slider control with 2 thumbs (range slider). Values range is between minimumValue and maximumValue (from 0 to 1 by default). The left thumb isn't able to go on the right side of the right thumb, and vice versa. Control enables multitouch (to use 2 fingers at 2 thumbs at the same time).

Please check Demo project for a basic example on how to use MARKRangeSlider.

• minimumValue - the minimum value of the slider's range (readonly)
• maximumValue - the maximum value of the slider's range (readonly)
• leftValue - the value of the left thumb (readonly)
• rightValue - the value of the right thumb (readonly)
• minimumDistance - the distance between 2 thumbs (thumbs can't be closer to each other than this distance)
• pushable - allows the user to push both controls
• disableOverlapping - disables the overlaping of thumb controls
• sendInstantUpdates - allows the user to select between instant updates and after completing drag of thumb

• (void)setMinValue:(CGFloat)minValue maxValue:(CGFloat)maxValue
• (void)setLeftValue:(CGFloat)leftValue rightValue:(CGFloat)rightValue

Images are customizable, default ones are used when no image is provided.

• trackImage - track background image
• rangeImage - range background image
• leftThumbImage - left thumb image
• rightThumbImage - right thumb image

- (void)viewDidLoad {
    // ...
    self.rangeSlider = [[MARKRangeSlider alloc] initWithFrame:CGRectZero];
    [self.rangeSlider addTarget:self
                         action:@selector(rangeSliderValueDidChange:)
               forControlEvents:UIControlEventValueChanged];

    [self.rangeSlider setMinValue:0.0 maxValue:1.0];
    [self.rangeSlider setLeftValue:0.2 rightValue:0.7];

    self.rangeSlider.minimumDistance = 0.2;

    [self.view addSubview:self.rangeSlider];
    // ...
}

- (void)rangeSliderValueDidChange:(MARKRangeSlider *)slider {
    NSLog(@"%0.2f - %0.2f", slider.leftValue, slider.rightValue);
}
