Facebook IOS SDK 3.1.1与Xcode 4.5.2错误

Question

我是iOS版Facebook SDK新手。 为什么我在构建项目时遇到此错误...

我只需从Facebook SDK的ios教程中创建一个基本步骤的新项目。

• 下载Facebook SDK（我使用3.1.1）
• Xcode（我使用4.5.2）
• 在Other Linker Flags
上的Build Setting中添加“-lsqlite3.0”
• 添加FacebookSDK.framework
• 添加FacebookSDKResources.bundle
• 添加FBUserSettingsViewResources.bundle

我尝试构建，一切正常..所以我继续在AppDelegate上编写基本实现

- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation {
    return [FBSession.activeSession handleOpenURL:url];
}

和

#import <FacebookSDK/FacebookSDK.h>

当我尝试构建时，错误即将发生......这是日志

ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我发现这很奇怪，因为我使用与Scrumptious示例相同的SDK和相同的设置，并且示例运行良好..同时我收到此错误...

任何想法？

Answer 1

我得到了答案... Facebook IOS SDK 3.1需要更多框架才能使用.. 需要＆＃39;帐户＆＃39; Ad＆＃39; AdSupport＆＃39;和＆＃39;社交＆＃39; IOS6上提供的框架。因为Facebook SDK 3.1是基于IOS6 ..

创建的

注意：如果您希望自己的应用也为旧版本的操作系统构建，则应使用可选标志用于特定于iOS6的框架。它看起来像这样。
