The Swift Package Manager is a tool for managing the distribution of Swift code. It’s integrated with the Swift build system to automate the process of downloading, compiling, and linking dependencies.
To integrate ALProgressView click File -> Swift Package -> Add Package Dependency and insert:
https://github.com/alxrguz/ALProgressView
ALProgressView is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod 'ALProgressView'If you prefer not to use either of the aforementioned dependency managers, you can integrate ALProgressView into your project manually. Put Source/ALProgressView folder in your Xcode project.
import ALProgressView
class MyViewController: UIViewController {
private lazy var progressRing = ALProgressRing()
private lazy var progressBar = ALProgressBar()
override func viewDidLoad() {
super.viewDidLoad()
view.addSubview(progressRing)
view.addSubview(progressRing)
// MARK: ALProgressRing
// Setup layout
progressRing.translatesAutoresizingMaskIntoConstraints = false
progressRing.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
progressRing.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true
// Make sure to set the view size
progressRing.widthAnchor.constraint(equalToConstant: 180).isActive = true
progressRing.heightAnchor.constraint(equalToConstant: 180).isActive = true
// MARK: ALProgressBar
// Setup layout
progressBar.translatesAutoresizingMaskIntoConstraints = false
progressBar.topAnchor.constraint(equalTo: progressRing.bottomAnchor, constant: 20).isActive = true
progressBar.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
progressBar.widthAnchor.constraint(equalTo: titleLabel.widthAnchor).isActive = true
// Make sure to set the view height
progressBar.heightAnchor.constraint(equalToConstant: 10).isActive = true
// Setting progress
progressRing.setProgress(0.8, animated: true)
progressBar.setProgress(0.6, animated: true)
}
}You can also run ExampleApp and play with the parameters there
You can customize the buttons, headers and indicators colors depending on their state.
/// Set track color
/// If you don't need a gradient, just set the same values for `startColor` and `endColor`
progressView.startColor = .systemPink
progressView.endColor = .systemRed
/// Set groove color
progressView.grooveColor = .systemRed progressView.duration = 2 // Duration of the ring's fill animation.
progressView.timingFunction = .easeOutExpo // Timing function of the ring's fill animation.
/// The following use of setProgress (_ value: Int, animated: Bool)
/// will take into account the new parameters
progressView.setProgress(0.8, animated: true)Let's take a look at the timingFunction parameter, it is of type ALTimingFunction, which contains the following types of animations:
There is a good cheat sheet available here.
progressBar.startAngle = -.pi / 2 // The start angle of the ring to begin drawing.
progressRing.endAngle = 1.5 * .pi // The end angle of the ring to end drawing.
progressRing.startGradientPoint = .init(x: 0.5, y: 0) // The starting poin of the gradient
progressRing.endGradientPoint = .init(x: 0.5, y: 1) // The ending position of the gradient.
// Sets the line width for progress ring and "groove" ring
progressRing.lineWidth = 10
// Or, if you need to separate these parameters, use
progressRing.ringWidth = 10
progressRing.grooveWidth = 8 progressBar.barEdgeInset = 1.5 // Distance between groove and progress bar.ALProgressView is under MIT license. See the LICENSE file for more info.
