Installation

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

pod 'ConnectedDots'

Usage

You can create the view through code or InterfaceBuilder

To configure control from code use

//Total number of dots
dots.numberOfDots = 8

//Default fill color
dots.defaultColor = .blue

//Dot radius
dots.dotRadius = 20.0

//Width of line that connects dots
dots.connectorLineWidth = 6.0

//Whether to show number inside dot
dots.showText = true

//Dots number font
dots.textFont = UIFont.systemFont(ofSize: 20.0)

//Dots number text color
dots.textColor = .darkGray

//Filled dots text color
dots.filledDotTextColor = .white

//Change to start dot text from different number (*default is 0*)
dots.textStartingNumber = 0

//Change dot selection outline color and width
dots.selectionOutlineColor = .red
dots.selectionOutlineWidth = 2.0

//Change content insets 
dots.insets = UIEdgeInsets(top: 0, left: 20, bottom: 0, right: 10)

There are three options available for dots selection:

  • none - user can't select dot by tapping on it

  • direct - user selects dot by tapping on it

  • progressive - works more like UIPageControl. Tapping from the right side selects next dot. Tapping from the left side selects the previous dot.

Default is direct. Change it from code:

dots.selectionType = .progressive

Use delegate if you want to limit selection of some dots

dots.delegate = self

func connectedDots(_ connectedDots: ConnectedDots, shouldSelectDotAt index: Int) -> Bool {
	return index % 2 == 0
}

To set dots fill color use following functions

//Apply fill color to dot at index
dots.setFillColor(.orange, forDotWithIndex: 1)

//Remove fill color for dot at index
dots.resetDotFillColor(atIndex: 1)

//Remove fill color for all dots
dots.resetFillColors()

To select dot programmatically

//Select dot at index
dots.selectDot(atIndex: 6)

//Deselect dot
dots.deselectDot()

//Get selected dot index
dots.selectedDotIndex

To be notified about dot selection change use Value Changed event. Create connection to IBAction from Interface Builder or use:

dots.addTarget(self, action: #selector(self.dotsSelectionChanged(_:)), for: .valueChanged)
