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了FBSDK之后，我的AppDelegate出现了一个错误，我似乎无法修复：

/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]?)'

给出错误的实际功能如下：

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

此功能是Facebook登录工作所必需的。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;

请有人帮忙！

Answer 1

我在使用Swift 1.2升级到XCode 6.3之后也遇到了这个问题。

问题似乎是sourceApplication类型已在函数中从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)
}

所以它应该是：

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

另请注意从AnyObject到AnyObject?的更改。如果没有改变，编译器仍然会抱怨。
