我有一个星期试图从 Facebook 显示 shareDialog，但没有任何效果，我的登录按钮正在工作，我在 Android 中的工作正常，但 IO 不工作，我已经从 Facebook 安装了我的 SDK，我把所有文件夹固定到项目中，但似乎没有什么对我有用，我已经为 facebookSDK https://github.com/facebookarchive/facebook-swift-sdk/blob/master/MigrationGuide.md进行了迁移
并且不起作用，我做错了什么，这是我的 AppDelegate.swift：
import UIKit
import FBSDKCoreKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
// Override point for customization after application launch.
ApplicationDelegate.shared.application(
application,
didFinishLaunchingWithOptions: launchOptions
)
return true
}
func application(
_ app: UIApplication,
open url: URL,
options: [UIApplication.OpenURLOptionsKey : Any] = [:]
) -> Bool {
return ApplicationDelegate.shared.application(
app,
open: url,
options: options
)
}
func applicationDidBecomeActive(_ application: UIApplication) {
AppEvents.activateApp()
}
// MARK: UISceneSession Lifecycle
func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
// Called when a new scene session is being created.
// Use this method to select a configuration to create the new scene with.
return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
}
func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {
// Called when the user discards a scene session.
// If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
// Use this method to release any resources that were specific to the discarded scenes, as they will not return.
}
}
这是 ViewController.swift：
import UIKit
import FBSDKLoginKit
import FBSDKShareKit
class ViewController: UIViewController {
@IBAction func ShareButton(_ sender: Any) {
let alert = UIAlertController(title : "Comparte", message:"Comparte con amigos", preferredStyle: .actionSheet)
let actionOne = UIAlertAction(title: "Comparte en facebook", style: .default) { (UIAlertAction) in
let sharePhoto = SharePhoto()
sharePhoto.imageURL = URL(string: "https://www.hola.com/imagenes/actualidad/20171204102954/adelanto-portada-revista-hola/0-514-626/adelanto-hola1-t.jpg")
let content = SharePhotoContent()
content.photos = [sharePhoto]
self.showShareDialog(content)
}
alert.addAction(actionOne)
self.present(alert, animated: true, completion: nil)
}
override func viewDidLoad() {
super.viewDidLoad()
let loginButton = FBLoginButton(permissions: [ .publicProfile ])
loginButton.center = view.center
view.addSubview(loginButton)
// Do any additional setup after loading the view.
}
func showShareDialog<C: SharingContent>(_ content: C, mode: ShareDialog.Mode = ShareDialog.Mode.automatic) {
let dialog = ShareDialog(fromViewController: self, content: content, delegate: self as? SharingDelegate)
dialog.mode = mode
dialog.show()
}
func sharer(_ sharer: Sharing, didCompleteWithResults results: [String: Any]) {
print("success")
let title = "Share Success"
let message = "Thank You"
let alertController = UIAlertController.init(title: title, message: message, preferredStyle: UIAlertController.Style.alert)
self.present(alertController, animated: true, completion: nil)
}
func sharer(_ sharer: Sharing, didFailWithError error: Error) {
print("error")
let title = "Share Failed"
let message = "Something went wrong. Please try again"
let alertController = UIAlertController.init(title: title, message: message, preferredStyle: UIAlertController.Style.actionSheet)
self.present(alertController, animated: true, completion: nil)
}
func sharerDidCancel(_ sharer: Sharing) {
print("canceled")
let title = "Share Cancelled"
let message = "Share on Facebook was Cancelled"
let alertController = UIAlertController.init(title: title, message: message, preferredStyle: UIAlertController.Style.alert)
self.present(alertController, animated: true, completion: nil)
}
}
