Facebook SDK 3.0 HelloFacebookSample构建错误 [英] Facebook SDK 3.0 HelloFacebookSample build errors

问题描述

我在编译Facebook SDK 3.0随附的HelloFacebookSample应用程序时遇到问题.

I'm having trouble compiling the HelloFacebookSample app that comes with Facebook SDK 3.0.

首先，我应该说我正在使用Xcode 4.0.2，iOS SDK 4.3和OS X 10.6.8. (我一直在努力寻找一种无需升级到Lion或Mountain Lion即可下载Xcode 4.2的方法，我不愿意这样做.)

Firstly, I should say I'm using Xcode 4.0.2, iOS SDK 4.3 and OS X 10.6.8. (I'm struggling to find a way to download Xcode 4.2 without upgrading to Lion or Mountain Lion, which I'm reluctant to do.)

当我尝试构建示例项目时，出现以下构建错误:

When I try to build the sample project, I get the following build errors:

1)程序中出现意外的"@"

1) Unexpected '@' in program

int main(int argc, char *argv[])
{
    @autoreleasepool {    // error on this line
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([HFAppDelegate class]));
    }
}

2)预期标识符

- (BOOL)application:(UIApplication *)application 
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation {
    // attempt to extract a token from the url
    return [FBSession.activeSession handleOpenURL:url];    // error on this line
}

- (void)applicationWillTerminate:(UIApplication *)application {
    // FBSample logic
    // if the app is going away, we close the session object
    [FBSession.activeSession close];                       // error on this line
}

我可以解决"这些问题(不确定是否正确解决了这些问题)，但是随后出现以下链接错误:

I can "resolve" these problems (not sure if I resolved them correctly), but then I then get the following linking error:

找不到框架帐户

Framework not found Accounts

命令/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/clang失败，退出代码为1

有人可以帮我吗?如果我什至无法构建示例项目，我将不会很幸运将Facebook集成到我的应用程序中！

Can anyone help me at all? I won't have much luck integrating Facebook into my app if I can't even build the sample projects!

推荐答案

我解决了所有问题.看来该示例并不立即与iOS 4.3或Xcode 4.0.2兼容.这是我所做的:

I resolved all the issues. It appears the sample is not immediately compatible with iOS 4.3 or Xcode 4.0.2. Here's what I did:

1)程序中的@意外；更改为以下内容:

1) Unexpected @ in program; changed to the following:

int main(int argc, char *argv[])
{
    NSAutoreleasePool *pool = [NSAutoreleasePool new];
    return UIApplicationMain(argc, argv, nil, NSStringFromClass([HFAppDelegate class]));
}

2)预期标识符；替换

2) Expected identifier; replaced

    return [FBSession.activeSession handleOpenURL:url];    // error on this line
...
    [FBSession.activeSession close];                       // error on this line

使用

    return [[FBSession activeSession] handleOpenURL:url];
...
    [[FBSession activeSession] close];

3)找不到框架帐户；事实证明它不是必需的，所以我只是从项目导航器的框架"组中删除了该框架.

3) Framework not found Accounts; turns out it's not required, so I just deleted the framework from the Frameworks group in the Project Navigator.

4)我忘了在原始帖子中说:关键字strong是未知的，因此我在文件 FacebookSDK/FacebookSDK.h 的顶部将其作为retain宏如下:

4) I forgot to say in my original post: keyword strong was unknown, so I macro'd it as retain at the top of the file FacebookSDK/FacebookSDK.h as follows:

#define strong retain

现在，HelloFacebookSample应用程序可以编译，没有错误或警告，并且可以正常运行.与Facebook的所有互动均有效.

And now the HelloFacebookSample app compiles with no errors or warnings and it works fine. All interactions with Facebook work.
