Question

我在我的应用中使用FBConnect。登录操作表按钮的标题是“登录Facebook”和“LogOut 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-来自回答评论的警报表代码：

 -(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]; 
}

Answer 1

当然，根据Facebook连接的状态，只显示一个不同的UIActionSheet，只显示这两个按钮。

怎么样：

-(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)必须为(season.isConnect)。一切都是好的！但仍然是一个问题。登录后 - 注销和分享显示很棒但不起作用！这意味着如果用户点击退出按钮，再次出现登录窗口！为什么？我认为，因为FBLoginButton，当delet这个方法我的UIActionSheet没有显示

！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];
    }

}

iPhone：是否可以隐藏和取消隐藏UIACtionSheet按钮？
