FacebookImagePicker：用Swift编写的Facebook相册照片选择器

GBHFacebookImagePicker是Facebook用Swift编写的相册照片选择器，旨在提供一种将图片选择到Facebook帐户的简单方法。选取器提供一个简单的界面，类似于本机 iOS 照片选取器。
必要时，此选取器负责所有身份验证（来自网络或使用本机 Facebook 应用程序）。如果在登录期间不接受照片的权限，则选取器会提示另一个权限的请求。

特征

• [x] 使用 Facebook SDK 登录并显示用户的相册或标记的照片
• [x] 显示每个相册的图片
• [x] 处理被拒绝的Facebook照片许可

Example

In your terminal :

pod try GBHFacebookImagePicker

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

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 protocol :GBHFacebookImagePickerDelegate

// 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 FacebookImage {
    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 = FacebookImagePicker() 
picker.presentFacebookAlbumImagePicker(from: self, delegate: self) 

Customisation

You can apply some customisation. To do it you can use the FacebookPickerConfig structure.

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.

Translation

FacebookImagePicker is currently written in english. If you need translation for the permission popup (or whatever thing), just add this line in your localized file :

"Pictures" = "<your_translation>";
"Oups" = "<your_translation>";
"You need to allow photo's permission." =  "<your_translation>";
"Allow" = "<your_translation>";
"Close" = "<your_translation>";
"Album(s)" = "<your_translation>";
"Photos of You" = "<your_translation>";
""No picture(s) in this album." = "<your_translation>";"
