Signal Strength Indicator in Swift

I would like to tell about a UI component, which shows an indicator of the connectivity, like a standard iOS cellular indicator. Maybe be helpful for somebody. The control has simple customization: color, edges, spacing.

Installation

CocoaPods:

pod 'SignalStrengthIndicator'

Manual:

Copy SignalStrengthIndicator.swift to your project.

Usage

There is an example in the repository. The example shows how to add the control via storyboard (Interface Builder). Also, I can easily add via code.

let indicator = SignalStrengthIndicator()
// Set up frame
view.addSubview(indicator)

For controling the level of the indicator you need to use the following property:

indicator.level = .good

There is 6 cases of indication:

enum Level: Int {
  case noSignal
  case veryLow
  case low
  case good
  case veryGood
  case excellent
}

Customization

Color:

indicator.color = UIColor.gray

Spacing between bars:

indicator.spacing = 5

Margins:

indicator.edgeInsets = UIEdgeInsets(top: 10, left: 10, bottom: 10, right: 10)

The example and source code of the UI control you can find here.
