如何在swift上設置facebook SDK？

Question

我在快速的應用程序中設置了facebook sdk。有一部分我需要連接到delagate並且facebook提供了此代碼：

// AppDelegate.m 
#import <FBSDKCoreKit/FBSDKCoreKit.h> 

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 
    [[FBSDKApplicationDelegate sharedInstance] application:application 
    didFinishLaunchingWithOptions:launchOptions]; 
    return YES; 
} 

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation { 
    return [[FBSDKApplicationDelegate sharedInstance] application:application 
    openURL:url 
    sourceApplication:sourceApplication 
    annotation:annotation 
    ]; 
} 

這是obj-c。這是什麼快捷版本？

Answer 1

只需將這些方法添加到您的AppDelegate.swift文件中即可初始化FacebookSDK。

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

func applicationDidBecomeActive(application: UIApplication) { 
     // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface. 
     FBSDKAppEvents.activateApp() 
    }

這是兩種方法必要的，但我也有問題解析日launchOptions

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 
     // Override point for customization after application launch. 
     FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions) 
     return true 
    } 

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