##Installation

####CocoaPods available on CocoaPods. Just add the following to your project Podfile:

pod 'SKPhotoBrowser'
use_frameworks!

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

github "suzuki-0000/SKPhotoBrowser"

####Manually Add the code directly into your project.

##Usage See the code snippet below for an example of how to implement, or example project would be easy to understand.

// add SKPhoto Array from UIImage
var images = [SKPhoto]()
let photo = SKPhoto.photoWithImage(UIImage())// add some UIImage
images.append(photo) 

// create PhotoBrowser Instance, and present. 
let browser = SKPhotoBrowser(photos: images)
browser.initializePageIndex(0)
browser.delegate = self
presentViewController(browser, animated: true, completion: {})

from web URLs:

// URL pattern snippet
var images = [SKPhoto]()
let photo = SKPhoto.photoWithImageURL("https://placehold.jp/150x150.png")
photo.shouldCachePhotoURLImage = false // you can use image cache by true(NSCache)
images.append(photo)

// create PhotoBrowser Instance, and present. 
let browser = SKPhotoBrowser(photos: images)
browser.initializePageIndex(0)
presentViewController(browser, animated: true, completion: {})

If you want to use zooming effect from an existing view, use another initializer:

// e.g.: some tableView or collectionView.
func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
   let cell = collectionView.cellForItemAtIndexPath(indexPath) as! ExampleCollectionViewCell
   let originImage = cell.exampleImageView.image! // some image for baseImage 
   let browser = SKPhotoBrowser(originImage: originImage, photos: images, animatedFromView: cell) 
   browser.initializePageIndex(indexPath.row)
   presentViewController(browser, animated: true, completion: {})
}

Custom

Toolbar

You can customize the toolbar(back/forward, counter) button.

• displayCounterLabel (default is true)
• displayBackAndForwardButton (default is true). If you dont want the toolbar at all, you can set displayToolbar = false (default is true)

let browser = SKPhotoBrowser(originImage: originImage, photos: images, animatedFromView: cell)
browser.displayToolbar = false                // all tool bar will be hidden
browser.displayCounterLabel = false           // counter label will be hidden
browser.displayBackAndForwardButton = false   // back / forward button will be hidden

Photo Captions

Photo captions can be displayed simply bottom of PhotoBrowser. by setting the caption property on specific photos:

let photo = SKPhoto.photoWithImage(UIImage())
photo.caption = "Lorem Ipsum is simply dummy text of the printing and typesetting industry."
images.append(photo)

SwipeGesture

vertical swipe can enable/disable:

let browser = SKPhotoBrowser(originImage: originImage, photos: images, animatedFromView: cell)
browser.disableVerticalSwipe = true 

StatusBar

you can hide statusbar forcely using property:

let browser = SKPhotoBrowser(originImage: originImage, photos: images, animatedFromView: cell)
browser.isForceStatusBarHidden = true 

Delegate

There's some trigger point you can handle using delegate.

• didShowPhotoAtIndex(index:Int)
• willDismissAtPageIndex(index:Int)
• didDismissAtPageIndex(index:Int)

let browser = SKPhotoBrowser(originImage: originImage, photos: images, animatedFromView: cell)
browser.delegate = self

// MARK: - SKPhotoBrowserDelegate
func didShowPhotoAtIndex(index: Int) {
// when photo will be shown
}

func willDismissAtPageIndex(index: Int) {
// when PhotoBrowser will be dismissed
}

func didDismissAtPageIndex(index: Int) {
// when PhotoBrowser did dismissed
}
