Ios iPad情节串连板上的序列标识符

我有一个应用程序设置了集合视图，其中一个有一系列单元格，然后切换到另一个全屏单元格，以重新创建一个照片库。我在iPhone上可以很好地实现这一点，但当我在iPad上尝试时，点击第一个单元格应该可以识别索引路径上的项目，并将其传递到全屏视图，而这并没有发生

我相信原因是我正在寻找一个segue标识符，因为这是一个通用的应用程序，我在两种用途中使用相同的代码。在iPhone故事板上，我可以设置segue标识符，但这不会出现在iPad故事板上。问题是…。这正常吗？有办法解决吗？我可以根据要求提供代码，但此时我觉得它与问题无关

代码是：

第一个集合视图
