我已經看過這裏的每一個線程，我有最新的Parse SDK（1.8.5），我有最新的Facebook SDK（4.6）。我使用iOS9和Swift 2.0的Xcode版本7.0.1。我已經反覆閱讀Facebook API文檔頁面，以確保我不會錯過任何東西以及解析API文檔。這裏是我的視圖控制器Facebook登錄問題-canOpenURL：URL失敗：「fbauth2：///」 - error：「（null）」
import ParseFacebookUtilsV4
import Parse
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
let permissions = ["public_profile"]
PFFacebookUtils.logInInBackgroundWithReadPermissions(permissions) {
(user: PFUser?, error: NSError?) -> Void in
if let user = user {
if user.isNew {
print("User signed up and logged in through Facebook!")
} else {
print("User logged in through Facebook!")
}
} else {
print("Uh oh. The user cancelled the Facebook login.")
}
}
}
這裏是AppDelegate中：
import UIKit
import CoreData
import Parse
import Bolts
import FBSDKCoreKit
import ParseFacebookUtilsV4
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool
{
Parse.enableLocalDatastore()
// Initialize Parse.
Parse.setApplicationId("removed",
clientKey: "removed")
PFFacebookUtils.initializeFacebookWithApplicationLaunchOptions(launchOptions)
return true
}
func application(application: UIApplication,
openURL url: NSURL,
sourceApplication: String?,
annotation: AnyObject) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(application,
openURL: url,
sourceApplication: sourceApplication,
annotation: annotation)
}
這裏是info.plist中：

沒有編譯器的問題，但是當我運行它，我得到的
canOpenURL: failed for URL: "fbauth2:///" - error: "(null)"
-canOpenURL: failed for URL: "fbauth2:///" - error: "(null)"
當模擬tor只啓動一個空白屏幕，它不會在模擬器上路由Facebook登錄。
任何人都可以請幫忙！
重置您的模擬器：選擇模擬器， 選擇重置內容和設置， 並選擇重置選項。從[這裏]（http://stackoverflow.com/questions/32676334/ios-9-facebook-login-simulator-canopenurl-failed-for-url-fbauth2-erro）。 – Monkpit
也嘗試過幾次。不解決問題。 –
我在Facebook上看到了這個文檔，但無論在模擬器上，它都沒有帶我去登錄Facebook頁面 –
