GNGaugeView

A visual gauge built with Swift that can be used as a speedometer to track speed of travel. Useful for giving a visual display of the speed of walking, running or any other kind of fitness activity.

Installing

$ pod install GNGaugeView

or in your Podfile

pod 'GNGaugeView'

Usage

Subclass a UIView with GNGaugeView in Storyboard or instantiate a GNGaugeView. Specify any desired configurations such as a minimum and maximum speed for your gauge. Use the function rotateGauge(newSpeed: CGFloat) to rotate the gauge to a new speed. In the example below we use a UISlider to rotate the gauge:

import UIKit 

class ViewController: UIViewController {

  @IBOutlet weak var gaugeView: GNGaugeView!
  
  @IBOutlet weak var gaugeSlider: UISlider!
  
  override func viewDidLoad() {
        super.viewDidLoad()
        
        gaugeView.minSpeed = 0
        
        gaugeView.maxSpeed = 30
        
   }
   
   @IBAction func sliderDidChange(_ sender: UISlider) {
        
        let sliderValue = sender.value
        
        let speed = gaugeView.maxSpeed * CGFloat(sliderValue)
        
        gaugeView.rotateGauge(newSpeed: speed)
        
    }

}

Example

An example project is included which shows how to use GNGaugeView with Core Motion to get the speed of walking or running.
