The view was designed for a recipe app. I needed a simple ratings view that was also setable by the user and would work in a collection view.

A light weight star rating UI component for iOS written in Swift.

StarView is a minimalist design, with a few customizations.

Note: This view is not currently IBDesignable

• Can be used to show ratings followed by number of ratings.
• If isUserInteractionEnabled user can provied a rating by panning or tapping on stars, rating will be shown.
• Gives haptic Feedback when user selects/deselect one full star
• Round stars to the nears whole

Variables you can modifiy in the view inspectinable with type and default value.

• starCount:Int = 5 : Number of stars in view
• ratingCount:Int = 0 : Amount of ratings for item
• rating:CGFloat = 0.0 : Rating for item
• roundRating:Bool = false : Will use whole numbers in rating
• fillColor:UIColor = UIColor.systemYellow : Star fill color
• stokeColor :UIColor = UIColor.black : Star outline (strokeColor) color

Stars are automaticity update when when the rating or ratingCount changes. Also calling starView.updateStar() will force a update. So make your changes before calling!

Git clone the repo and add LiteStarView framework to your exsiting xcode project.

Note: You might need build the framework.

How to add LiteStarView framework to a existing project.

Add the following in your Podfile.

'LiteStarView', '~> 1.0'

Create and drop a UIView then set the class to StarView.

There are many way to layout this view but a height constraint is needed for the stars to be drawn correctly. Take a look at the examples below

This is the formula to help calculate the width.

(height * amountOfStars) + (height * 2)

Examples

Note: Also need to set Center Horizontal in Safe Area to the parent.

Formula Example: (40 * 5) + (40 * 2) = 280

- Show rating (Non-interactive)

- User provided rating (interactive)

Once linked to your viewController. You can programmatically set/get rating and rating counter.

import UIKit
import LiteStarView
class ViewController: UIViewController {

    @IBOutlet weak var starView: StarView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // set rating and ratingCount programmable
        starView.rating = 3.5
        starView.ratingCount = 50
        // get current rating
        let currentRating = starView.rating
    }
}
