🖼 ImageSlideshow

Swift image slideshow with circular scrolling, timer and full screen viewer

📱 Example

To run the example project, clone the repo, and run pod install from the Example directory first.

🔧 Installation

CocoaPods

ImageSlideshow is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'ImageSlideshow', '~> 1.0.0'

Carthage

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

github "zvonicek/ImageSlideshow" "1.0.0"

Carthage does not include InputSources for external providers (due to dependency on those providers) so you need to grab the one you need from ImageSlideshow/Classes/InputSources manually.

Manually

One possibility is to download a builded framework (ImageSlideshow.framework.zip) from releases page and link it with your project (underLinked Frameworks and Libraries in your target). This is, however, currently problematic because of rapid Swift development -- the framework is builded for a single Swift version and may not work on previous/future versions.

Alternatively can also grab the whole ImageSlideshow directory and copy it to your project. Be sure to remove those external Input Sources you don't need.

Note on Swift 2.3 and Swift 3 support

Version 1.0 supports Swift 3. For Swift 2.2 and Swift 2.3 compatible code use version 0.6 or branch swift-2.3.

🔨 How to use

Add ImageSlideshow view to your view hiearchy either in Interface Builder or in code.

Loading images

Set images by using setImageInputs method on ImageSlideshow instance with an array of InputSources. By default you can use ImageSource which takes UIImage or few other InputSources for most popular networking libraries. You can also create your own input source by implementing InputSource protocol.

Library	InputSource name	Pod
AlamofireImage	AlamofireSource	pod "ImageSlideshow/Alamofire"
AFNetworking	AFURLSource	pod "ImageSlideshow/AFURL"
SDWebImage	SDWebImageSource	pod "ImageSlideshow/SDWebImage"
Kingfisher	KingfisherSource	pod "ImageSlideshow/Kingfisher"

slideshow.setImageInputs([
  ImageSource(image: UIImage(named: "myImage"))!, 
  ImageSource(image: UIImage(named: "myImage2"))!,
  AlamofireSource(urlString: "https://images.unsplash.com/photo-1432679963831-2dab49187847?w=1080"),
  KingfisherSource(urlString: "https://images.unsplash.com/photo-1432679963831-2dab49187847?w=1080")
])

Configuration

Behaviour is configurable by those properties:

• slideshowInterval - in case you want automatic slideshow, set up the interval between sliding to next picture
• zoomEnabled - enables zooming
• circular - enables circular scrolling
• pageControlPosition - configures position of UIPageControll (hidden, inside scroll view or under scroll view)
• contentScaleMode - configures the scaling (UIViewContentMode.ScaleAspectFit by default)
• draggingEnabled - enables dragging
• currentPageChanged - closure called on page change
• preload - image preloading configuration (all images are preloaded by default)

Full Screen view

There is also a possibility to open full-screen image view using attached FullScreenSlideshowViewController. The simplest way is to call:

override func viewDidLoad() {
  let gestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(ViewController.didTap))
  slideshow.addGestureRecognizer(gestureRecognizer)
}

func didTap() {
  slideshow.presentFullScreenController(from: self)
}

FullScreenSlideshowViewController can also be instantiated and configured manually if more advanced behavior is needed.
