GBHFacebookImagePicker is Facebook's album photo picker written in Swift, built to provide a simple way to pick picture into Facebook account. The picker provides a simple interface like the native iOS photo picker. This picker takes care of all authentication (from the web or with the native Facebook app) when necessary. If the photo's permission isn't accepted during the login, the picker prompts another permission's request.

Or to run the example project manually, clone the repo, and run pod install from the Example directory first.

Don't forget to replace the current Facebook App's ID with your own in the plist file (Open as > Source code). Like this :

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleTypeRole</key>
        <string>Editor</string>
        <key>CFBundleURLSchemes</key>
            <array>
                <string>fb<YOUR_FACEBOOK_APP_ID></string>
            </array>
    </dict>
</array>
<key>FacebookAppID</key>
<string><YOUR_FACEBOOK_APP_ID></string>

Just in case, for public application (which can be use in the AppStore), you need to send your Facebook's App in review to have user's photos permission.

Usage

• You need to set up your application correctly to work with Facebook : https://developers.facebook.com/docs/ios/getting-started and https://developers.facebook.com/docs/ios/ios9

• Import the library :

import GBHFacebookImagePicker

• Then, implement the GBHFacebookImagePickerDelegate protocol :

// MARK: - GBHFacebookImagePicker Protocol

func facebookImagePicker(imagePicker: UIViewController,
                         successImageModels: [GBHFacebookImage],
                         errorImageModels: [GBHFacebookImage],
                         errors: [Error?]) {
    // Append selected image(s)
    // Do what you want with selected image 
    self.imageModels.append(contentsOf: successImageModels)
}

func facebookImagePicker(imagePicker: UIViewController, didFailWithError error: Error?) {
    print("Cancelled Facebook Album picker with error")
    print(error.debugDescription)
}

// Optional
func facebookImagePicker(didCancelled imagePicker: UIViewController) {
    print("Cancelled Facebook Album picker")
}

// Optional
func facebookImagePickerDismissed() {
    print("Picker dismissed")
}

The imageModel contain :

public class GBHFacebookImage {
    public var image: UIImage? // The image, not nil only if image is selected
    public var normalSizeUrl: String? // Normal size picture url
    public var fullSizeUrl: String? // Full size source picture url
    public var imageId: String? // Picture id
}

• Display picker :

let picker = GBHFacebookImagePicker() 
picker.presentFacebookAlbumImagePicker(from: self, delegate: self) 

Customisation

You can apply some customisation. To do it you can use the GBHFacebookPickerConfig structure like this :

// Multiple selection settings 
GBHFacebookImagePicker.pickerConfig.allowMultipleSelection = true // False by default  

// Navigation bar title 
GBHFacebookImagePicker.pickerConfig.title = "MyCustomTitle"

// Navigation barTintColor
GBHFacebookImagePicker.pickerConfig.uiConfig.navBarTintColor = UIColor.red

// Close button color 
GBHFacebookImagePicker.pickerConfig.uiConfig.closeButtonColor = UIColor.white

// Global backgroundColor 
GBHFacebookImagePicker.pickerConfig.uiConfig.backgroundColor = UIColor.red

// Status bar style (.default style by default)
GBHFacebookImagePicker.pickerConfig.uiConfig.statusbarStyle = .lightContent

// Navigation bar title color
GBHFacebookImagePicker.pickerConfig.uiConfig.navTitleColor = UIColor.white

// Navigation bar tintColor
GBHFacebookImagePicker.pickerConfig.uiConfig.navTintColor = UIColor.white

// Album's name color 
GBHFacebookImagePicker.pickerConfig.uiConfig.albumsTitleColor = UIColor.white

// Album's count color 
GBHFacebookImagePicker.pickerConfig.uiConfig.albumsCountColor = UIColor.white

// Selected border color 
GBHFacebookImagePicker.pickerConfig.uiConfig.selectedBorderColor = UIColor.red

// Selected border width 
GBHFacebookImagePicker.pickerConfig.uiConfig.selectedBorderWidth = 4.0

/// Preview photos size (normal by default)
GBHFacebookImagePicker.pickerConfig.uiConfig.previewPhotoSize = .full

// Maximum selected pictures 
GBHFacebookImagePicker.pickerConfig.maximumSelectedPictures = 4

// Display tagged album 
GBHFacebookImagePicker.pickerConfig.taggedAlbumName = "Tagged photos"

// Tagged album name
GBHFacebookImagePicker.pickerConfig.displayTaggedAlbum = true

// Number of picture per row (4 by default)
GBHFacebookImagePicker.pickerConfig.picturePerRow = 3

// Space beetween album photo cell (1.5 by default)
GBHFacebookImagePicker.pickerConfig.cellSpacing = 2.0

// Perform animation on picture tap (true by default)
GBHFacebookImagePicker.pickerConfig.performTapAnimation = true

// Show check style with image and layer (true by default)
GBHFacebookImagePicker.pickerConfig.uiConfig.showCheckView = false

// Change checkview background color
GBHFacebookImagePicker.pickerConfig.uiConfig.checkViewBackgroundColor = UIColor.red

Aditionals informations

• About tagged photos : the tagged photos are displayed in an album (hide by default, see customisation section to display it) with the name "Photos of You". You can change this default name in the settings. The tagged album's cover is the facebook account profile picture, which are retrieved with a special call to the graph API.
