Installation

pod 'SwiftPhotoGallery'

Implementation

  • Import the framework in your view controller

    import SwiftPhotoGallery
    
  • Create an instance

    let gallery = SwiftPhotoGallery(delegate: self, dataSource: self)
    
  • Customize the look

    gallery.backgroundColor = UIColor.black
    gallery.pageIndicatorTintColor = UIColor.gray.withAlphaComponent(0.5)
    gallery.currentPageIndicatorTintColor = UIColor.white
    gallery.hidePageControl = false
    
  • Implement the datasource

    let imageNames = ["image1.jpeg", "image2.jpeg", "image3.jpeg"]
    

func numberOfImagesInGallery(gallery: SwiftPhotoGallery) -> Int { return imageNames.count }

func imageInGallery(gallery: SwiftPhotoGallery, forIndex: Int) -> UIImage? { return UIImage(named: imageNames[forIndex]) }


* **Implement the delegate**
```swift
func galleryDidTapToClose(gallery: SwiftPhotoGallery) {
    // do something cool like:
    dismiss(animated: true, completion: nil)
}
  • Present the gallery swift present(gallery, animated: true, completion: nil)

Full Example

class ViewController: UIViewController, SwiftPhotoGalleryDataSource, SwiftPhotoGalleryDelegate {

    let imageNames = ["image1.jpeg", "image2.jpeg", "image3.jpeg"]
    var index: Int = 2

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    @IBAction func didPressShowMeButton(sender: AnyObject) {
        let gallery = SwiftPhotoGallery(delegate: self, dataSource: self)

        gallery.backgroundColor = UIColor.black
        gallery.pageIndicatorTintColor = UIColor.gray.withAlphaComponent(0.5)
        gallery.currentPageIndicatorTintColor = UIColor.white
        gallery.hidePageControl = false

        present(gallery, animated: true, completion: nil)

        /*
        /// Or load on a specific page like this:

        present(gallery, animated: true, completion: { () -> Void in
            gallery.currentPage = self.index
        })
        */

    }

    // MARK: SwiftPhotoGalleryDataSource Methods

    func numberOfImagesInGallery(gallery: SwiftPhotoGallery) -> Int {
        return imageNames.count
    }

    func imageInGallery(gallery: SwiftPhotoGallery, forIndex: Int) -> UIImage? {
        return UIImage(named: imageNames[forIndex])
    }

    // MARK: SwiftPhotoGalleryDelegate Methods

    }

}
