A Simple Star Rating View for displaying and entering star ratings

by iOS Example

StarRatingView

StarRatingView is a simple Star Rating View for displaying star ratings and entering them (by touching the stars). It's written for iOS, in Swift 5.1 (UIKit, not SwiftUI). It also works with Interface Builder

Installation

Copy the 3 files to your XCode projects

Usage

Interface Builder

  1. Add a UIView to your interface
  2. In the Identiy Inspector, change Class to StarRatingView
  3. In the Attributes Inspector you can now set:
  • the rating (Float between 0 and 5)
  • the star color
  • the Star Rounding Raw Value - IBInspectable can't handle enums, hence the raw value, see ENUM code below
  1. By checking User Interaction Enabled users can touch the view to enter a star rating. The rating stars updates while touching.

Code

  1. Create an instance of StarRatingView
    let starRatingView = StarRatingView(frame: CGRect(origin: .zero, size: CGSize(width: 250, height: 50)), rating: 3.5, color: UIColor.systemOrange, starRounding: .roundToHalfStar)
    Natural aspect ratio is 5 width to 1 height.
  2. Add the view as a subview
  3. Properties (set and get)
  • starRatingView.rating (type: Float)
  • starRatingView.starColor (type: UIColor)
  • starRatingView.starRounding (type: StarRounding)
  • starRatingView.isUserInteractionEnabled (type: Bool)

The StarRounding ENUM

public enum StarRounding: Int {
case roundToHalfStar = 0
case ceilToHalfStar = 1
case floorToHalfStar = 2
case roundToFullStar = 3
case ceilToFullStar = 4
case floorToFullStar = 5
}

Comments

  • The stars are SF Symbols and as such resize automatically without loosing image quality
  • Feel free to use in your projects. A mention would be appreciated.
  • Feel free to clone, download, create pull requests etc. I'm open to expanding functionality and improving where necessary (i'm not an expert)
