iphone - 在 ios Facebook SDK 3.0 中登录时应用程序崩溃

Question

我的应用程序使用 Facebook 身份验证。如果设备上没有安装 Facebook 应用程序，它可以正常工作；如果用户未登录 Facebook 应用程序，它也适用于具有 Facebook 应用程序的设备。但是，如果用户已经登录到 Facebook 应用程序，我的应用程序会显示登录页面两三秒钟，然后崩溃并说

 -[SBJsonParser errorTrace]: unrecognized selector sent to instance 0x48ad90

崩溃日志显示异常类型:EXC_CRASH (SIGTRAP)有没有人帮忙？

Answer 1

最后我通过添加解决了我的问题

-(id) errorTrace{
    return [NSArray arrayWithObjects:@"error1", nil];
}

在 SBJsonParser 中。我不知道它是如何工作的。
