Xcode按钮：有些工作，有些不工作？

Question

我正在尝试为我的高级项目设计一个应用程序，因此对iOS编码来说相当新。我创建了一个.xib视图控制器，并在一些卡片图像上添加了许多按钮。另一个玩家的手上有一个大按钮，并在每个玩家自己的牌上切断较小的按钮。

我已经为每个按钮添加了UIAlertControllers，打算让弹出窗口允许玩家玩或丢弃自己的牌，或者发送一些关于其他玩家的信息。

对于其他玩家的按钮，警报弹出正常，但底牌的警告完全没有。我已经检查过它们都连接到IBActions，代码几乎与IS工作的按钮相同。有什么想法吗？

这一切都包含在gameViewController.m: btnTop正确执行其操作中，而btnBottom1 - btnBottom5则不执行任何操作。

- (IBAction)btnTop:(id)sender{
    NSLog(@"Top Button Pressed. Displaying AlertView.");
    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Give Information" message:@"Would you like to give information about color or number?" preferredStyle:UIAlertControllerStyleAlert];
    UIAlertAction *actionColor = [UIAlertAction actionWithTitle:@"Color" style:UIAlertActionStyleDefault
                                                        handler:^(UIAlertAction *action)
                                  {
                                      [self giveColorInfo];
                                  }];
    UIAlertAction *actionNumber = [UIAlertAction actionWithTitle:@"Number" style:UIAlertActionStyleDefault handler:nil];
    UIAlertAction *actionCancel = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleDefault handler:nil];
    [alertController addAction:actionColor];
    [alertController addAction:actionNumber];
    [alertController addAction:actionCancel];
    [self presentViewController:alertController animated:YES completion:nil];
