## Support for Storyboard

    @IBOutlet weak var holaView: Hola!

    override func viewDidLoad() {
        super.viewDidLoad()


        let _image1: UIImage = UIImage(named:"image1")!
        let _image2: UIImage = UIImage(named:"image2")!
        let _image3: UIImage = UIImage(named:"image3")!
        let _image4: UIImage = UIImage(named:"image2")!

        let imageArray: [UIImage] = [_image1,_image2,_image3,_image4]
        let viewArray: [UIView] = [...........yourViews]

        holaView.prepareImagesForStoryboard(uiimageArray: imageArray, rotation: .vertical)

        holaView.prepareViewsForStoryboard(viewArray: viewArray, rotation: .horizontal)

    }

Use prepareImagesForStoryboard or prepareViewsForStoryboard methods for preparing of @IBOutlet variable.

Init

public init(frame: CGRect, viewArray uiviewArray:[UIView], _ rotation: rotationWay)

If you build pager with array of UIView you should use this init function.

let simple: Hola = Hola(frame: CGRect(), viewArray: viewArray, .horizontal)


Another `init function`
```swift
public init(frame: CGRect, imageArray uiimageArray:[UIImage],_ rotation:rotationWay)

For creating Hola with array of UIImage, use this init function to generate it.

Here is the another example for usage.

let simple: Hola = Hola(frame: CGRect(), imageArray: imageArray, .vertical)

Structs

public enum rotationWay {
case horizontal
case vertical
}

rotationWay is used for specify Hola's rotation as horizontalhorizontal or vertical.

Manually Installation

git clone REPO_URL
cd Hola/
use Hola.swift

Cons

The main cons of the Hola is that using the UIScrollView. If you use 1000 image for the this UIScrollView, the app wants to all image on memory, so thats not practible. If you build such a tool with UICollectionView, it will handle the photos with lazy loading, so just some of images will be load into memory which is currently showing to the user on the screen. The main difference and disadvantage of it is about not memory friendly.
