OProgressView

You use the OProgressView class to show an ellipse to depict the progress of a task over time.

Supports any size ellipse, not just circles.
Provides a label that autopopulates with the current progress value (as a percent).
Set progress manually or by observing a Progress instance.
Available in Interface Builder.

Installation

Carthage

To install using Carthage, add the following to your project's Cartfile:

github "epau/OProgressView"

Manually

Download and drag into your project all files within the Source folder:

OProgressView.swift
CGPoint+PointOnEllipse.swift
FloatingPoint+DegreesToRadians.swift
UIBezierPath+Percentage.swift

Requirements

Xcode 8
Swift 3.0
iOS 8.0 +

Usage

Initialize an instance of OProgressView just like any other UIView.

let oProgressView = OProgressView()

// Or pass in a frame
let oProgressView = OProgressView(frame: CGRect(x: 0, y: 0, width: 100, height: 100))

Adjust the current progress, optionally animating the change.

oProgressView.setProgress(0.80, animated: true)

Or observe a Progress instance.

let progress = Progress(totalUnitCount: 100)

oProgressView.observedProgress = progress

OProgressView's API should feel very familiar as it is designed to match UIProgressView's API.
Many of the same properties are exposed to control the style of the progress view.

// The color shown for the portion of the progress bar that is not filled.
var trackTintColor: UIColor?
// An image to use for the portion of the track that is not filled.
var trackImage: UIImage?
// The color shown for the portion of the progress bar that is filled.
var progressTintColor: UIColor?
// An image to use for the portion of the progress bar that is filled.
var progressImage: UIImage?

There are some additional properties as well.

// The width of the track around the ellipse.
var trackWidth: CGFloat
// The label to display the current progress as a percentage.
var progressLabel: UILabel
// The color shown in the inside of the circle.
var centerBackgroundColor: UIColor?
