无法转到view controller。我不知道。有什么问题吗？有什么想法请帮助我。感谢advance的帮助。

首先：

检查您的delegate.friendslistaray中是否包含任何数据。我看到你把它记录下来了。让我们在这里提供这些数据

我会将if（[delegate.FriendsListaray count]！=0）中的所有代码删除到friendRequest startWithCompletionHandler块中。当然，在for（）之后

如果以上都不适合你。尝试此操作并替换以下代码。然后开始一步一步地编写另一段代码

我已经按你的要求做了。我建议尝试使用以下方法：-

   if (FBSession.activeSession.isOpen) {
      FBRequest *friendRequest = [FBRequest requestForGraphPath:@"me/friends?fields=name,picture,birthday,location"];
      [friendRequest startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error)
      {
          NSArray *data = [result objectForKey:@"data"];
          for (FBGraphObject<FBGraphUser> *friend in data)
          {
               [delegate.friendsListArray addObject:friend];
          }
          if ([delegate.friendsListArray count] > 0) {
              BirthdayList *birthdaylist=[[BirthdayList alloc]initWithNibName:@"BirthdayList" bundle:nil];
              [self.navigationController pushViewController:birthdaylist animated:YES];
          } else {
              UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Friend not found" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
              [alertView show];
          }
      }];

   }
}
}

它是一个帮助器方法，用于为

[UIApplicationLegate ApplicationIDBecomeActive:

正确解析的会话状态 Facebook登录流，专门支持应用程序切换登录

e、 g-

- (BOOL)handleOpenURL:(NSURL*)url;

我希望它能解决你的问题。如果您还有疑问，我将详细说明。

试试这个-

首先，在应用程序委托中实现所有facebook sdk委托方法

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation 
{
// We need to handle URLs by passing them to FBSession in order for SSO authentication to work.

return [FBSession.activeSession handleOpenURL:url];
}

现在，在您的appDelegate中-

- (IBAction)loginWithFacebookButtonTapped:(id)sender
{
    IntubeAppDelegate *delegat = (IntubeAppDelegate*)[[UIApplication sharedApplication] delegate];
    [delegat doLoginAndSwitch];
}

也可以切换回您的应用程序-

-(void) doLoginAndSwitch
{      
    [self openSessionWithAllowLoginUI:YES];
}

- (BOOL)openSessionWithAllowLoginUI:(BOOL)allowLoginUI
{
    NSArray *permissions = [NSArray arrayWithObjects:@"email", nil]; 
    return [FBSession openActiveSessionWithPublishPermissions:permissions
                                      defaultAudience:FBSessionDefaultAudienceFriends
                                         allowLoginUI:YES
                                    completionHandler:^(FBSession *session, FBSessionState state, NSError *error) {

                                        [self sessionStateChanged:session
                                                            state:state
                                                            error:error];

                                    }];
}

-(BOOL)openSessionWithAllowPublishStreamPermission:(BOOL)allowLoginUI
{
    NSArray *permissions = [NSArray arrayWithObjects:@"publish_actions",@"publish_stream", nil];

    [[FBSession activeSession] requestNewPublishPermissions:permissions defaultAudience:FBSessionDefaultAudienceEveryone completionHandler:^(FBSession *session, NSError *error){
}];
     return YES;
}

- (void)sessionStateChanged:(FBSession *)session
              state:(FBSessionState)state
              error:(NSError *)error
{
    switch (state) {
        case FBSessionStateOpen:
            if(!error)
            {
              //  NSLog(@"FBSessionStateOpen :- logged in");

                [self openSessionWithAllowPublishStreamPermission:YES];

              // Your code
            }
    }    
}
