License

Windless makes it easy to implement invisible layout loading view.

Requirements

  • iOS 8.0+
  • Xcode 9.0+
  • Swift 4.0+

Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods
Bash

CocoaPods 1.1+ is required to build Windless 4.0+.

To integrate Windless into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!

target '<Your Target Name>' do
    pod 'Windless', '~> 0.1.5'
end
Ruby

Then, run the following command:

$ pod install
Bash

Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage
Bash

To integrate Windless into your Xcode project using Carthage, specify it in your Cartfile:

github "Interactive-Studio/Windless" ~> 0.1.5
Ogdl

Run carthage update to build the framework and drag the built Windless.framework into your Xcode project.

Manually

If you prefer not to use either of the aforementioned dependency managers, you can integrate Windless into your project manually.

Usage

Code

import Windless

class ViewController: UIViewController {

    lazy var contentsView = UIView()
    
    var subView1 = UIView()
    var subView2 = UIView()

    override func viewDidLoad() {
        super.viewDidLoad()

        self.view.addSubview(contentsView)
        contentsView.addSubview(subView1)
        contentsView.addSubview(subView2)
        
        // start
        contentsView.windless
                .setupWindlessableViews([subView1, subView2])
                .start()
                
        // stop
        contentsView.windless.end()
    }

}
Swift

Storyboard, Xib

If you use Storyboard or xib, you only need to set the isWindlessable flag to true for the views you want to show as fake in the view inspector of the view, and you do not have to pass the view through the setupWindlessableViews method.

import Windless

class ViewController: UIViewController {

    @IBOutlet weak var contentsView: UIView!

    override func viewDidLoad() {
        super.viewDidLoad()

        contentsView.windless.start()
    }
}
Swift

Multiline

Depending on the lineHeight value and thespacing value, UILabel and UITextView will reconstruct the layout when the windless animation runs.

public protocol CanBeMultipleLines {

    var lineHeight: CGFloat { get set }

    var spacing: CGFloat { get set }
}
Swift

Custom Options

There are several customizable options in Windless.

public class WindlessConfiguration {
    
    /// The direction of windless animation. Defaults to rightDiagonal.
    public var direction: WindlessDirection = .rightDiagonal
    
    /// The speed of windless animation. Defaults to 1.
    public var speed: Float = 1
    
    /// The duration of the fade used when windless begins. Defaults to 0.
    public var beginTime: CFTimeInterval = 0
    
    /// The time interval windless in seconds. Defaults to 4.
    public var duration: CFTimeInterval = 4
    
    /// The time interval between windless in seconds. Defaults to 2.
    public var pauseDuration: CFTimeInterval = 2
    
    /// gradient animation timingFunction default easeOut
    public var timingFuction: CAMediaTimingFunction = .easeOut
    
    /// gradient layer center color default .lightGray
    public var animationLayerColor: UIColor = .lightGray
    
    /// Mask layer background color default .groupTableViewBackground
    public var animationBackgroundColor: UIColor = .groupTableViewBackground
    
    /// The opacity of the content while it is windless. Defaults to 0.8.
    public var animationLayerOpacity: CGFloat = 0.8
}
Swift

To set the options, use the apply method as shown below.

import Windless

class ViewController: UIViewController {

    @IBOutlet weak var contentsView: UIView!

    override func viewDidLoad() {
        super.viewDidLoad()

        contentsView.windless
            .apply {
                $0.beginTime = 1
                $0.pauseDuration = 2
                $0.duration = 3
                $0.animationLayerOpacity = 0.5
            }
            .start()
    }
}
Swift

Looks

The isWindlessable value determines how the loading view looks. The images below show how the loading screen will look according to the isWindlessable value.

isWindlessable= ?
