RangeSeekSlider

Overview

RangeSeekSlider provides a customizable range slider like a UISlider. This library is based on TomThorpe/TTRangeSlider (Objective-C) and made with Swift.

Demo

You can try on Appetize.io

or

Build Xcode project.

1. Open RangeSeekSlider.xcodeproj.
2. Change Scheme to RangeSeekSliderDemo
3. Run

Usage

Add the RangeSeekSlider like you would with any other UIControl. Either:

• Add a view in your storyboard/xib and change its Class and Module to RangeSeekSlider. You can set all the properties in the Attributes Inspector and see a live preview:

or

• Create the RangeSeekSlider in code using RangeSeekSlider() then add it as a subview to your code and set the relevant autolayout properties or frame.

The default slider ranges from 0.0 -> 100.0 and has 10.0 preselected as the minimum, and 90.0 as the maximum.

Values that the user has selected are exposed using the selectedMinValue and selectedMaxValue properties. You can also use these properties to change the selected values programatically if you wish.

Other customisation of the control is done using the following properties:

tintColor

The tintColor property (which you can also set in Interface Builder) sets the overall color of the control, including the color of the line, the two handles, and the labels.

It is safe to change the tintColor at any time, if the control is currently visible the color change will be animated into the new color.

minValue

The minimum possible value to select in the range

maxValue

The maximum possible value to select in the range

selectedMinValue

The preselected minumum value (note: This should be less than the selectedMaxValue)

selectedMaxValue

The preselected maximum value (note: This should be greater than the selectedMinValue)

minLabelFont

The font of the minimum value text label. If not set, the default is system font size 12.0.

maxLabelFont

The font of the maximum value text label. If not set, the default is system font size 12.0.

numberFormatter

Each handle in the slider has a label above it showing the current selected value. If you change number format, update each properties of NumberFormatter. By default, this is displayed as a decimal format.

hideLabels

When set to true the labels above the slider controls will be hidden. Default is false.

labelsFixed

Fixes the labels above the slider controls. If true, labels will be fixed to both ends. Otherwise labels will move with the handles. Default is false.

minDistance

The minimum distance the two selected slider values must be apart. Default is 0.0.

maxDistance

The maximum distance the two selected slider values must be apart. Default is CGFloat.greatestFiniteMagnitude.

minLabelColor

The color of the minimum value text label. If not set, the default is the tintColor.

maxLabelColor

The color of the maximum value text label. If not set, the default is the tintColor.

handleColor

If set it will update the color of the handles. Default is tintColor.

colorBetweenHandles

The colorBetweenHandles property sets the color of the line between the two handles.

handleBorderColor

If set it will update the color of the handle borders. Default is tintColor.

initialColor

The color of the entire slider when the handle is set to the minimum value and the maximum value. Default is nil.

disableRange

If true, the control will mimic a normal slider and have only one handle rather than a range.

In this case, the selectedMinValue will be not functional anymore. Use selectedMaxValue instead to determine the value the user has selected.

enableStep

If true the control will snap to point at each step (property) between minValue and maxValue. Default value is disabled.

step

If enableStep is true, this controls the value of each step. E.g. if this value is 20, the control will snap to values 20,40,60...etc. Set this is you enable the enableStep property.

handleImage

If set the image passed will be used for the handles.

handleDiameter

If set it will update the size of the handles. Default is 16.0.

selectedHandleDiameterMultiplier

If set it update the scaling factor of the handle when selected. Default is 1.7. If you don't want any scaling, set it to 1.0.

lineHeight

Set the height of the line. It will automatically round the corners. If not specified, the default value will be 1.0.

handleBorderWidth

If set it will update the size of the handle borders. Default is 0.0

labelPadding

If set it will update the size of the padding between label and handle. Default is 8.0

minLabelAccessibilityLabel

The label displayed in accessibility mode for minimum value handler. If not set, the default is empty String.

maxLabelAccessibilityLabel

The label displayed in accessibility mode for maximum value handler. If not set, the default is empty String.

minLabelAccessibilityHint

The brief description displayed in accessibility mode for minimum value handler. If not set, the default is empty String.

maxLabelAccessibilityHint

The brief description displayed in accessibility mode for maximum value handler. If not set, the default is empty String.

func setupStyle()

When subclassing RangeSeekSlider and setting each item in setupStyle(), the design is reflected in Interface Builder as well.

Requirements

• Swift 3.0+
• iOS 9.0+

Installation

Carthage

RangeSeekSlider is available through Carthage. To install it, simply add the following line to your Cartfile:

⚠️Warning⚠️

When installed with Carthage, @IBDesignable can't be available (Carthage Issue). But we have a workaround is shown in Stack Overflow. It is able to use @IBDesignable by subclassing RangeSeekSlider.

@IBDesignable class CustomRangeSeekSlider: RangeSeekSlider {}

CocoaPods

RangeSeekSlider is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'RangeSeekSlider'

Manually

Download and drop RangeSeekSlider/Sources folder in your project.
