## Requirements

- iOS 8.0+
- Xcode 9.0+
- Swift 4.0+

## Installation

### CocoaPods

[CocoaPods](http://cocoapods.org) is a dependency manager for Cocoa projects. You can install it with the following command:

```bash
$ gem install cocoapods
```

> CocoaPods 1.1+ is required to build Windless 4.0+.

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

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

target '' do
pod 'Windless', '~> 0.1.5'
end
```

Then, run the following command:

```bash
$ pod install
```

### Carthage

[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with [Homebrew](http://brew.sh/) using the following command:

```bash
$ brew update
$ brew install carthage
```

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

```ogdl
github "Interactive-Studio/Windless" ~> 0.1.5
```

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

```swift
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()
}

}
```

### 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.

```swift
import Windless

class ViewController: UIViewController {

@IBOutlet weak var contentsView: UIView!

override func viewDidLoad() {
super.viewDidLoad()

contentsView.windless.start()
}
}
```

### Multiline

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

```swift
public protocol CanBeMultipleLines {

var lineHeight: CGFloat { get set }

var spacing: CGFloat { get set }
}
```

|------- | -------
| |

### Custom Options

There are several customizable options in **Windless**.

```swift
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
}
```

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

```swift
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()
}
}
```

If you want to know more detailed usage, please refer to Example.

## 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```= 🌀
