Description

OpalImagePicker is a multiple selection Image Picker for iOS written in Swift. Meant to be a drop in replacement for UIImagePickerController. Compatible with both Swift and Objective-C.

Swift 4 and 5 Compatibility

  • Swift 5.0: >= 2.1.0 - Latest is 2.1.0 Download here.
  • Swift 4.2: >= 2.0.0 - Latest is 2.0.0 Download here.
  • Swift 4.0: >= 1.5.0 - Latest is 1.7.1 Download here. CocoaPods be sure to fix the release (pod 'OpalImagePicker', '~> 2.1.0')

Usage

OpalImagePicker is presented much like UIImagePickerController. As a normal View Controller.

let imagePicker = OpalImagePickerController()   
presentOpalImagePickerController(imagePicker, animated: true, 
    select: { (assets) in
        //Select Assets
    }, cancel: {
        //Cancel
    })

Or

let imagePicker = OpalImagePickerController()
imagePicker.imagePickerDelegate = self        
present(imagePicker, animated: true, completion: nil)

OpalImagePicker has three delegate methods to notify you when images have been selected, or the picker has been cancelled. This is only necessary if you choose not to use the presentOpalImagePickerController(_:animated:select:cancel:completion:) function.

optional func imagePicker(_ picker: OpalImagePickerController, didFinishPickingAssets assets: [PHAsset])
optional func imagePickerDidCancel(_ picker: OpalImagePickerController)

OpalImagePicker also allows you to use external images. You may want to use images from Facebook, Instagram, or Twitter for example. You can do this either using the delegate methods below or the following function in Swift presentOpalImagePickerController(_: animated: maximumSelectionsAllowed: numberOfExternalItems: externalItemsTitle: externalURLForIndex: selectAssets: selectExternalURLs: cancel: completion:) function.

optional func imagePickerNumberOfExternalItems(_ picker: OpalImagePickerController) -> Int
optional func imagePicker(_ picker: OpalImagePickerController, imageURLforExternalItemAtIndex index: Int) -> URL?    
optional func imagePickerTitleForExternalItems(_ picker: OpalImagePickerController) -> String
optional func imagePicker(_ picker: OpalImagePickerController, didFinishPickingExternalURLs urls: [URL])

OpalImagePicker supports allowing users to customize user interface features

let imagePicker = OpalImagePickerController()

//Change color of selection overlay to white
imagePicker.selectionTintColor = UIColor.white.withAlphaComponent(0.7)

//Change color of image tint to black
imagePicker.selectionImageTintColor = UIColor.black

//Change image to X rather than checkmark
imagePicker.selectionImage = UIImage(named: "x_image")

//Change status bar style
imagePicker.statusBarPreference = UIStatusBarStyle.lightContent

//Limit maximum allowed selections to 5
imagePicker.maximumSelectionsAllowed = 5

//Only allow image media type assets
imagePicker.allowedMediaTypes = Set([PHAssetMediaType.image])

//Change default localized strings displayed to the user
let configuration = OpalImagePickerConfiguration()
configuration.maximumSelectionsAllowedMessage = NSLocalizedString("You cannot select that many images!", comment: "")
imagePicker.configuration = configuration
