我有一个现有的应用程序，其中在打开应用程序时，进度条的默认步骤是UserType, Credentials, Email, Password, Confirm Password, Agreement and Done，该应用程序需要对其进行一些更改Stepped Progress Bar，顺便说一下我使用FlexibleSteppedProgressBarpod 作为进度条。我的问题是，该应用程序有三个 (3) UserTypes。两种用户类型（User1，User2）应该有如下 8 个步骤UserType, Credentials, Email, Password, Confirm Password, Agreement and Done，而一种用户类型（User3）只有 7 个步骤（没有Agreement步骤）。User3当用户点击进度条中的步骤应该只有 7 个步骤以及用户点击时如何修改进度条User1 User2用户类型，应保留默认的 8 步进度条。我有点困惑，因为我是 swift 编程的新手，我正在修改一个需要修改的现有应用程序，而我不是创建该应用程序的原始应用程序。我尝试了一些修改，我添加了另外两个结构，其中包含 7 个步骤和 8 个步骤，点击User37 个步骤的结构将被调用并变成 7 个步骤，但MasterViewController布局仍然没有修改原来的 8 个步骤，只是在修改后的 7 个步骤中重叠，这意味着看起来我的应用程序中出现了两个重叠的进度条。
