Welcome to the documentation page for the CHCircleGaugeView library. This library provides a customizable circular gauge view for iOS applications, allowing users to easily visualize values within a range. The gauge can be utilized to display various types of data such as progress, speed, and any other metric that can be represented in a circular manner.

Installation

  1. Open your Xcode project.
  2. Navigate to the project directory using Finder.
  3. Create a ‘Podfile’ if you don’t have one. Otherwise, simply open it.
  4. Add the following line to your Podfile: pod 'CHCircleGaugeView'
  5. Save and close the Podfile.
  6. In Terminal, navigate to your project directory and run pod install.
  7. Once the installation is complete, open your project using .xcworkspace file.

Usage

To make use of the CHCircleGaugeView library, follow the steps below:

  1. In your view controller file, import the library using the following line:
    2. import CHCircleGaugeView
  2. Create an instance of CHCircleGaugeView:
    3. let gaugeView = CHCircleGaugeView(frame: CGRect(x: 0, y: 0, width: 200, height: 200))
  3. Configure the gauge view by setting its properties. For example:
    4. gaugeView.maxValue = 100
gaugeView.value = 75
gaugeView.unitOfMeasurement = "km/h"
  4. Add the gauge view to your view hierarchy:
    5. view.addSubview(gaugeView)
  5. Customize the appearance of the gauge view as desired:
    6. // Example customizations
gaugeView.backgroundColor = .white
gaugeView.trackColor = .lightGray
gaugeView.progressColor = .blue
  6. Update the value of the gauge view whenever necessary:
    7. gaugeView.value = 50

Customization

The CHCircleGaugeView library allows for various customizations to suit your application’s specific needs. Some of the key properties that can be customized include:

  • maxValue: The maximum value of the gauge.
  • value: The current value of the gauge.
  • unitOfMeasurement: The unit of measurement to be displayed.
  • trackColor: The color of the gauge’s background track.
  • progressColor: The color of the progress arc within the gauge.
  • ringWidth: The thickness of the gauge’s track and progress arc.
  • valueFont: The font used for displaying the value.
  • valueColor: The color of the value text.
  • unitOfMeasurementFont: The font used for displaying the unit of measurement.
  • unitOfMeasurementColor: The color of the unit of measurement text.
  • startAngle: The starting angle of the progress arc.
  • endAngle: The ending angle of the progress arc.
  • animationDuration: The duration of any value change animations.

Examples

Here is an example of how to use the CHCircleGaugeView library to create a circular progress gauge:

let progressGaugeView = CHCircleGaugeView(frame: CGRect(x: 0, y: 0, width: 200, height: 200))

progressGaugeView.maxValue = 100
progressGaugeView.value = 75
progressGaugeView.trackColor = .lightGray
progressGaugeView.progressColor = .blue

view.addSubview(progressGaugeView)

With the provided code, you will have a circular gauge view displaying a progress of 75 out of 100, with a light gray track and a blue progress arc. Feel free to experiment with different configurations to achieve the desired visual effect.

Conclusion

In conclusion, the CHCircleGaugeView library is a powerful tool for visually representing circular gauges in iOS applications. By following the provided documentation and examples, you can easily integrate and customize the gauge to suit your specific needs. Enjoy building beautiful and informative circular gauges for your app!
