Ios 如何在swift中创建动态阶梯进度条？
我有一个现有的应用程序，在打开应用程序时，默认的进度条步骤是Ios 如何在swift中创建动态阶梯进度条？,ios,swift,uiprogressbar,Ios,Swift,Uiprogressbar,我有一个现有的应用程序，在打开应用程序时，默认的进度条步骤是用户类型、凭据、电子邮件、密码、确认密码、协议和完成，应用程序需要对其进度条进行一些更改，顺便说一下，我使用了FlexibleSteppedProgressBarpod作为进度条。我的问题是，该应用程序有三（3）个用户类型。两种用户类型（User1、User2）应包含以下8个步骤用户类型、凭据、电子邮件、密码、确认密码、协议和完成，而一种用户类型（User3）仅包含7个步骤（无协议步骤）。当用户点击User3时，如何修改进度条进度条进度
用户类型、凭据、电子邮件、密码、确认密码、协议和完成进度条进行一些更改，顺便说一下，我使用了FlexibleSteppedProgressBar
pod作为进度条。我的问题是，该应用程序有三（3）个用户类型。两种用户类型（User1、User2）应包含以下8个步骤用户类型、凭据、电子邮件、密码、确认密码、协议和完成
，而一种用户类型（User3）仅包含7个步骤（无协议
步骤）。当用户点击User3
时，如何修改进度条进度条进度条中的步骤应仅为7个步骤，当用户点击User1 User2
用户类型时，应保留包含8个步骤的默认进度条。我有点困惑，因为我是swift编程新手，我正在修改一个需要修改的现有应用程序，而我不是最初创建该应用程序的人。
我尝试了一些修改，在点击User3
时添加了另外两个包含7个步骤和8个步骤的结构，7个步骤的结构将被调用并变成7个步骤，但是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，这意味着我的应用程序中出现了两个重叠的进度条
