NHPhotosViewer 0.1.2

Maintained by Ngo Hung.

You want to add pod 'NHPhotosViewer', '~> 0.1' similar to the following to your Podfile:

target 'MyApp' do
  pod 'NHPhotosViewer', '~> 0.1'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

pod try NHPhotosViewer

NHPhotosViewer 0.1.2

By

Simple photos viewer written in Swift.

NHPhotosViewer is designed to be presented within a navigation controller. Simply set the delegate (which must conform to NHPhotosViewControllerDelegate) and implement the 2 required delegate methods to provide the photo viewer with the data in the form of NHPhoto objects. You can create an NHPhoto object by providing a UIImage object, or a URL containing the path to a file or an image online.

Downloading/caching of images are done via Kingfisher library.

Status

Project under development. Missing many features. Just a very simple image gallery for now.

Code Example

import NHPhotosViewer
...

override func viewDidLoad() {
    let urls : [String] =
    [   
        "http://somedomain.com/image.png",
        "http://somedomain.com/anotherimage.png",
        ...
    ]

    ...

    for url in urls {
        let photo = NHPhoto(url: URL(string: url)! )
        // set placeholder image if necessary
        //photo.placeholder_image = placeholderImg
        photos.append(photo)
    }

    self.viewer = NHPhotosViewController()
    self.viewer?.delegate = self
    self.viewer?.numOfColumns = 4

}

// open viewer with navigation controller
@IBAction func openViewer(_ sender: AnyObject) {

    self.viewer?.navigationItem.title = "Photos"
    self.navigationController?.pushViewController(self.viewer!, animated: false)

}

//NHPhotosViewControllerDelegate
func numOfPhotos(photoController: UIViewController ) -> Int{
    return photos.count
}

func photo(photoController: UIViewController, index: Int) -> NHPhoto {
    return photos[index]
}
