ios - Facebook SDK ios v4.4.0 didFinishLaunchingWithOptions

Question

我已经按照 Facebook 指南在我的 iOS 应用程序中实现了 Facebook SDK，并在我的 AppDelegate 中设置：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
 // more code

  return [[FBSDKApplicationDelegate sharedInstance] application:application didFinishLaunchingWithOptions:launchOptions];
}

现在，我还在我的应用程序中实现了切换，并且- (BOOL) application:(UIApplication *)application willContinueUserActivityWithType:(NSString *)userActivityType在应用程序从头开始时永远不会被调用，因为 FBSDKApplicationDelegate sharedInstance 返回 false。

[FBSDKApplicationDelegate sharedInstance]application:didFinishLaunchingWithOptions所以我的问题是：如果我不返回结果并返回我的自定义结果，会有任何副作用吗？例如：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
 // more code

  [[FBSDKApplicationDelegate sharedInstance] application:application didFinishLaunchingWithOptions:launchOptions];
  return YES;
}

Answer 1

简答NO。

[FBSDKApplicationDelegate application: didFinishLaunchingWithOptions:] 应该从 [UIApplicationDelegate application:didFinishLaunchingWithOptions:]AppDelegate 的方法为您的应用调用正确使用 Facebook SDK 的方法。

YES如果 url 用于 Facebook SDK，则此方法返回，NO如果不是。

在最新的 Facebook 入门文档中，他们提到了它

要发布来自 Facebook 登录或 Facebook 对话框（或任何需要切换到本机 Facebook 应用程序或 Safari 的操作）的结果，您需要连接AppDelegate到FBSDKApplicationDelegate. 在您的 AppDelegate.m 添加：

//  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
  ];
}
