私はプレーヤーを認証するためにこの機能を持っています.xcode8ベータ6まではうまくいきました：
func authenticateLocalPlayer()
{
print(#function)
// WillSignIn
self.delegate?.willSignIn?()
// The player authenticates in an asynchronous way, so we need a notification to inform when the authentication was completed successfully
// If the local player is already connected, return and notificate
if GameKitHelper.sharedGameKitHelper.localPlayer.isAuthenticated {
NotificationCenter.default.post(name: NSNotification.Name(rawValue: Constants.LocalPlayerIsAuthenticated), object: nil)
return
}
// Calling the authentication view controller
self.localPlayer.authenticateHandler = {(viewController: UIViewController?, error: NSError?) -> Void in
self.addLastError(error: error)
if (viewController != nil)
{
self.addAuthenticationViewController(authenticationViewController: viewController!)
}
// If the localPlayer authenticated successfully notificate
else if (self.localPlayer.isAuthenticated == true)
{
self.gameCenterConnected = true
print("Local player ID: \(self.localPlayer.playerID)")
print("Local player Alias: \(self.localPlayer.alias)")
NotificationCenter.default.post(name: NSNotification.Name(rawValue: Constants.LocalPlayerIsAuthenticated), object: nil)
}
// If the localPlayer failed to authenticate
else
{
self.gameCenterConnected = false
}
if (error != nil)
{
// Handle error here
}
}
}
今、私はこのエラーを受け取ります「タイプ '(UIViewController?, NSError?) -> Void' の値をタイプ '((UIViewController?, Error?) -> Void) に割り当てることはできません?' " この行に
self.localPlayer.authenticateHandler = {(viewController: UIViewController?, error: NSError?) -> Void in
self.addLastError(error: error)
if (viewController != nil)
何が起こっているのかわかりません。誰でも私を助けてくれますか？
