即使在 Xcode 6.3 中更新了 Facebook，AppDelegate 应用程序功能中的 Facebook SDK 错误

Question

所以我更新了 Xcode 并得到了一堆很容易修复的错误，但是在更新 FBSDK 之后，我的 AppDelegate 中出现了一个我似乎无法修复的错误：

/Users/wylerzahm/Desktop/AppName/AppName/AppDelegate.swift:23:58: Cannot invoke 'application' with an argument list of type '(UIApplication, openURL: NSURL?, sourceApplication: NSString?, annotation: [NSObject : AnyObject]?)'

实际给出错误的函数如下：

func application(application: UIApplication, openURL url: NSURL?, sourceApplication: NSString?, annotation: [NSObject: AnyObject]?) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
}

该功能是Facebook 登录功能所必需的。任何帮助表示赞赏。被调用的函数如下：

@interface FBSDKApplicationDelegate : NSObject

+ (instancetype)sharedInstance;

- (BOOL)application:(UIApplication *)application
        openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
     annotation:(id)annotation;


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions;

如果有人能帮忙请帮忙！

Answer 1

我在升级到 XCode 6.3 和 Swift 1.2 后也遇到了这个问题。

问题似乎是函数中的 sourceApplication 类型已从 NSString 更新为 String：

func application(application: UIApplication, openURL url: NSURL, sourceApplication: NSString?, annotation: AnyObject) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
}

所以应该是：

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject?) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
}

干杯！

编辑：如 Ruud Kalis 所述，注释类型也从 AnyObject 更新为 AnyObject?

另请注意从 AnyObject 到 AnyObject? 的变化。如果不更改，编译器仍会报错。
