GTProgressBar

GTProgressBar is a customisable progress bar. It supports both vertical and horizontal orientation, You can adjust many visual settings of the progress bar to suit your use case. Customisation can be done in both the Interface Builder and in code. Here is a preview from the example app:

Example App

To run the example project, clone the repo, and run pod install from the Example directory first.

Requirements

This component is written using Swift 5 so you will need to run Xcode 11 or higher.

Usage

Many properties of GTProgressBar can be configured. Most of them can be configured in Interface Builder (@IBInspectable).

• orientation: GTProgressBarOrientation This property allows you to specify the orientation of the bar: horizontal or vertical. By default it is set to horizontal

  progressBar.orientation = GTProgressBarOrientation.vertical

• @IBInspectable orientationInt: Int This property allows you to specify the orientation of the bar as Int. It defaults to horizontal. Current mapping is

  0 -> GTProgressBarOrientation.horizontal

  1 -> GTProgressBarOrientation.vertical

  progressBar.orientationInt = 1

• direction: GTProgressBarDirection This property allows you to specify the direction of the progress bar content: clockwise or anticlockwise. By default it is set to clockwise

  progressBar.direction = GTProgressBarDirection.anticlockwise

• @IBInspectable directionInt: Int This property allows you to specify the direction of the progress bar content as Int. It defaults to clockwise. Current mapping is

  0 -> GTProgressBarDirection.clockwise

  1 -> GTProgressBarDirection.anticlockwise

  progressBar.orientationInt = 1

• @IBInspectable progress: CGFloat

  This property specifies how much of the bar is filled. The allowed values are from 0.0 to 1.0 . Default is 0. If progress label is displayed the value provided in here will be displayed as % The following example will cause 50% of the bar to be filled. The label will show 50%

  progressBar.progress = 0.5

• @IBInspectable displayLabel: Bool

  This property specifies if the progress label should be displayed. Default is true.

  progressBar.displayLabel = false

• @IBInspectable barBorderColor: UIColor

  This property specifies the colour of the bar's border. Default is UIColor.black

  progressBar.barBorderColor = UIColor(red:0.35, green:0.80, blue:0.36, alpha:1.0)

• @IBInspectable barBackgroundColor: UIColor

  This property specifies the background colour of the progress bar within the control. Default is UIColor.white

  progressBar.barBackgroundColor = UIColor(red:0.77, green:0.93, blue:0.78, alpha:1.0)

• @IBInspectable barFillColor: UIColor

  This property specifies the fill colour of the progress bar. Default is UIColor.white

  progressBar.barFillColor = UIColor(red:0.35, green:0.80, blue:0.36, alpha:1.0)

• @IBInspectable barBorderWidth: CGFloat

  This property specifies the width of the progress bar's border. Default is 2

  progressBar.barBorderWidth = 1

• @IBInspectable barFillInset: CGFloat

  This property specifies the inset between the fill of the bar and its border. Default is 2

  progressBar.barFillInset = 1

• @IBInspectable labelTextColor: UIColor

  This property specifies the fill colour of the label. Default is UIColor.black

  progressBar.labelTextColor = UIColor(red:0.35, green:0.80, blue:0.36, alpha:1.0)

• progressLabelInsets: UIEdgeInsets

  This property specifies the insets for the progress label. Default is UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)

  progressBar.progressLabelInsets = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)

• @IBInspectable progressLabelInsetLeft: CGFloat

  This property allows you to specify the left property of the progressLabelInsets in the Interface Builder. Default is 0.

  progressBar.progressLabelInsetLeft = 5.0

• @IBInspectable progressLabelInsetRight: CGFloat

  This property allows you to specify the right property of the progressLabelInsets in the Interface Builder. Default is 0.

  progressBar.progressLabelInsetRight = 5.0

• @IBInspectable progressLabelInsetTop: CGFloat

  This property allows you to specify the top property of the progressLabelInsets in the Interface Builder. Default is 0.

  progressBar.progressLabelInsetTop = 5.0

• @IBInspectable progressLabelInsetBottom: CGFloat

  This property allows you to specify the bottom property of the progressLabelInsets in the Interface Builder. Default is 0.

  progressBar.progressLabelInsetBottom = 5.0

• @IBInspectable cornerRadius: CGFloat

  This property specifies the radius of corners. Default is 0.0

  progressBar.cornerRadius = 10.0

• font: UIFont

  This property allows you to specify the font for the progress label. Default is UIFont.systemFont(ofSize: 12)

  progressBar.font = UIFont.boldSystemFont(ofSize: 18)

• barMaxHeight: CGFloat?

  This property allows you to specify the max height of the progress bar. By default the progress bar will be sized to match the height of the whole view. If the max height is larger than the available view height it will be ignored.

  progressBar.barMaxHeight = 12

• @IBInspectable barMaxHeightInt: Int

  This property allows you to specify the max height of the progress bar as an integer in the Interface Builder. By default the progress bar will be sized to match the height of the whole view. If the max height is larger than the available view height it will be ignored. If you set this property to 0 there will be no restriction on the height of the bar.

  progressBar.barMaxHeightInt = 12

• barMaxWidth: CGFloat?

  This property allows you to specify the max width of the progress bar. By default the progress bar will be sized to match the available free width. If the max width is larger than the available width it will be ignored.

  progressBar.barMaxWidth = 12

• @IBInspectable barMaxWidthInt: Int

  This property allows you to specify the max width of the progress bar as an integer in the Interface Builder. By default the progress bar will be sized to match the available free width. If the max width is larger than the available width it will be ignored. If you set this property to 0 there will be no restriction on the width of the bar.

  progressBar.barMaxWidthInt = 12

• labelPosition: GTProgressBarLabelPosition

  This property allows you to specify on which side the progress label should be placed. Default is GTProgressBarLabelPosition.left

  progressBar.labelPosition = GTProgressBarLabelPosition.right

• @IBInspectable labelPositionInt: Int

  This property allows you to specify the position of the progress label using integers in the Interface Builder. Current mapping is

  0 -> GTProgressBarLabelPosition.left

  1 -> GTProgressBarLabelPosition.right

  2 -> GTProgressBarLabelPosition.top

  3 -> GTProgressBarLabelPosition.bottom

  progressBar.labelPosition = GTProgressBarLabelPosition.right

• cornerType: GTProgressBarCornerType

  This property allows you to specify the type of the corner (square or rounded). Default is GTProgressBarCornerType.rounded

  progressBar.cornerType = GTProgressBarCornerType.square

• @IBInspectable cornerTypeInt: Int

  This property allows you to specify the type of the corner using integers in the Interface Builder. Current mapping is

  0 -> GTProgressBarCornerType.square

  1 -> GTProgressBarCornerType.rounded

  progressBar.cornerTypeInt = GTProgressBarCornerType.rounded.rawValue

• animateTo(progress: CGFloat, completion: (() -> Void)?)

  This method animates the progress bar to the value specified. The allowed values are from 0.0 to 1.0 . If invalid value is provided it will be capped to the nearest allowed value. This method also accepts a completion callback executed when the animation completes.

  progressBar.animateTo(progress: 0.9) {
    print("Animation completed")
  }

To put it altogether here is an example configuration of GTProgressBar in code:

let progressBar = GTProgressBar(frame: CGRect(x: 0, y: 0, width: 300, height: 15))
progressBar.progress = 1
progressBar.barBorderColor = UIColor(red:0.35, green:0.80, blue:0.36, alpha:1.0)
progressBar.barFillColor = UIColor(red:0.35, green:0.80, blue:0.36, alpha:1.0)
progressBar.barBackgroundColor = UIColor(red:0.77, green:0.93, blue:0.78, alpha:1.0)
progressBar.barBorderWidth = 1
progressBar.barFillInset = 2
progressBar.labelTextColor = UIColor(red:0.35, green:0.80, blue:0.36, alpha:1.0)
progressBar.progressLabelInsets = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)
progressBar.font = UIFont.boldSystemFont(ofSize: 18)
progressBar.labelPosition = GTProgressBarLabelPosition.right
progressBar.barMaxHeight = 12
progressBar.direction = GTProgressBarDirection.anticlockwise

view.addSubview(progressBar)
