Question

当用户使用Facebook登录时，我试图找出崩溃的ios应用程序。每次都不会重现该错误，我只有很少的关于此问题的报告和一个崩溃日志：

我已将ShareKit库与子库中更新的Facebook版本集成，但我将Facebook.h导入ApplicationDelegate类，并通过http://developers.facebook.com/docs/tutorials/ios-sdk-tutorial/authenticate/

中的步骤将其直接用于授权

请告诉我在崩溃日志中查找问题的方法是什么？

ApplicationDelegate类包含：

- (void)applicationDidBecomeActive:(UIApplication *)application
{
    ....
    [FBSession.activeSession handleDidBecomeActive];
}

- (void)applicationWillTerminate:(UIApplication *)application
{
    ....  
    [FBSession.activeSession close];
}


/*
 * If we have a valid session at the time of openURL call, we handle
 * Facebook transitions by passing the url argument to handleOpenURL
 */
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    [ProgressHUD displayProcessingIndicator];

    // attempt to extract a token from the url
    return [FBSession.activeSession handleOpenURL:url];
}

/*
 * Callback for session changes.
 */
- (void)sessionStateChanged:(FBSession *)session state:(FBSessionState) state error:(NSError *)error
{
    switch (state) {
        case FBSessionStateOpen:
            if (!error) {
                // We have a valid session
            }
            break;
        case FBSessionStateClosed:
        case FBSessionStateClosedLoginFailed:    
            [FBSession.activeSession closeAndClearTokenInformation];
            break;
        default:
            break;
    }

    [[NSNotificationCenter defaultCenter] postNotificationName:@"FacebookSessionStateChangeNotification"
                                                        object:session];

    if (error) {
        [ProgressHUD hideIndicator];
    }
}

/*
 * Opens a Facebook session and optionally shows the login UX.
 */
- (void)openFacebookSession
{
    // To using the internal ios6 integration, call openActiveSessionWithReadPermissions method
    #pragma GCC diagnostic ignored "-Wdeprecated-declarations"
    [FBSession openActiveSessionWithPermissions:[NSArray arrayWithObject:@"email"]
                                   allowLoginUI:YES
                              completionHandler:^(FBSession *session, FBSessionState state, NSError *error) {
                                  [self sessionStateChanged:session state:state error:error];
                              }];
    #pragma GCC diagnostic warning "-Wdeprecated-declarations"
}

- (void)closeFacebookSession
{
    if (FBSession.activeSession.isOpen) {
        [FBSession.activeSession closeAndClearTokenInformation];
    }
}

非常感谢。
