我在我的应用程序中使用 FBConnect。登录操作表按钮的标题是“登录 Facebook”和“注销 Facebook”，但我想显示“登录 Facebook”和“发布到 Facebook”。目前，它看起来像这样......

...可能在这些方法中设置：

- (void)session:(FBSession*)session didLogin:(FBUID)uid {

    //Show button log out

}

- (void)sessionDidLogout:(FBSession*)session {

    //show button log in
}

Edit01-来自答案评论的警报表代码：

 -(IBAction)mySheet:(id)sender { 
    UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:@"FaceBook" 
                                                      delegate:self 
                                             cancelButtonTitle:@"Cancel" 
                                        destructiveButtonTitle:nil 
                                             otherButtonTitles:@"Share On the Facebook" , 
                                                                @"Log in Facebook" ,
                                                                @"LogOut Facebook" ,nil]; 
    [menu showInView:self.view]; 
    [menu release]; 
}

当然，根据 Facebook 连接的状态，只需使用这两个按钮显示不同的 UIActionSheet。

关于什么：

-(IBAction)mySheet:(id)sender
{
    if (alreadyLoggedInToFacebook) {
        UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:@"FaceBook"
            delegate:self  cancelButtonTitle:@"Cancel"
                destructiveButtonTitle:nil
                    otherButtonTitles: @"Share On the Facebook" ,  @"Log in Facebook" ,
                      @"LogOut Facebook" ,nil]; 
    } else {
        UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:@"FaceBook"
            delegate:self  cancelButtonTitle:@"Cancel"
                destructiveButtonTitle:nil
                    otherButtonTitles:  @"LogOut Facebook" ,nil]; 
    }
    [menu showInView:self.view]; 
    [menu release]; 
}

最后我实现了！(alreadyLoggedInToFacebook)必须是(season.isConnect)。一切都是好的 ！但还是有问题。登录后-注销并分享显示很棒，但效果不佳！这意味着如果用户点击注销按钮，登录窗口再次出现！为什么 ？我认为，这是因为FBLoginButton，当删除此方法时，我的 UIActionSheet 不显示

！这是我的代码：

-(IBAction)mySheet:(id)sender
{
    if (session.isConnected) {
        UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:@"FaceBook"
                                                          delegate:self  cancelButtonTitle:@"Cancel"
                                            destructiveButtonTitle:nil
                                                 otherButtonTitles: @"Share On the Facebook" , @"Log out Facebook" ,nil]; 
        [menu showInView:self.view]; 
        [menu release]; 


    } else {



        UIActionSheet *menu2 = [[UIActionSheet alloc] initWithTitle:@"FaceBook"
                                                           delegate:self  cancelButtonTitle:@"Cancel"
                                             destructiveButtonTitle:nil
                                                  otherButtonTitles:  @"Log in Facebook" ,
                                nil]; 

        [menu2 showInView:self.view]; 
        [menu2 release]; 
    }
}


- (void)actionSheet:(UIActionSheet *)menu2 didDismissWithButtonIndex:(NSInteger)buttonIndex {

if (buttonIndex != [menu2 cancelButtonIndex]) 
    {

        FBLoginDialog* login = [[FBLoginDialog alloc] initWithSession:session];
        [login show];
        [login release];
    }

}

- (void)actionSheet:(UIActionSheet *)menu didDismissWithButtonIndex2:(NSInteger)buttonIndex {



    if (buttonIndex != [menu cancelButtonIndex]) 
    {
        [session logout];
    }

}
