Facebook认证-认证过程中的空白白屏-iOS 10 GM，Swift 3

由于Swift 3-IOS10，Xcode 8 GM SDK，我在使用Facebook SDK进行身份验证结束时收到了空白的白屏。 它以前起过作用。AppDelegate中有一些警告：

也许这与此有关

编辑： 我知道这些函数已弃用，我尝试将它们更改为新函数，但FBSDKApplicationDelegate仍然请求旧的参数

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
    FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)

}

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: <#T##String!#>, annotation: <#T##Any!#>)
}

func应用程序（application:UIApplication，didFinishLaunchingWithOptions launchOptions:[UIApplicationLaunchOptions:Any]？=nil）->Bool{
FBSDKApplicationDelegate.sharedInstance（）.application（应用程序，didFinishLaunchingWithOptions:launchOptions）
}
func应用程序（uApp:UIApplication，打开url:url，选项：[uiApplicationOpenUrlOptions:Any]=[：]）->Bool{
返回FBSDKApplicationDelegate.sharedInstance（）.application（应用程序，打开：url，sourceApplication:，注释：）
}

正如您所看到的，问题在于第二个函数。

我知道这些函数在iOS 9中不受欢迎，因此我使用了其他函数及其自己的API

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)

}

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: options[UIApplicationOpenURLOptionsKey
        .sourceApplication] as! String!, annotation: options[UIApplicationOpenURLOptionsKey.annotation])
}

我知道这些函数在iOS 9中不推荐使用，所以我使用了其他函数及其自己的API

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)

}

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: options[UIApplicationOpenURLOptionsKey
        .sourceApplication] as! String!, annotation: options[UIApplicationOpenURLOptionsKey.annotation])
}

试试这个

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(app,open: url,sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as! String, annotation: options[UIApplicationOpenURLOptionsKey.annotation])
}

试试这个

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(app,open: url,sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as! String, annotation: options[UIApplicationOpenURLOptionsKey.annotation])
}
