It means the MainViewclass is defined twice or more.
这意味着MainView该类被定义了两次或更多次。
Check:
查看：
- If the
MainViewclass's@implementationappears in any.hfiles. It shouldn't. - If there are 2
MainViewclasses define by you and a third-party library. You may need to rename yourMainViewclass.
- 如果
MainView该类@implementation出现在任何.h文件中。不应该。 - 如果
MainView您定义了2 个类和一个第三方库。您可能需要重命名您的MainView班级。

I had this same problem when i add Reliability class to my code. I already included tree20 to my project which is having reliability class. So when I add the reliability class again to my class I got the same error. I removed the Reliability code from my project and it works perfect.
当我将 Reliability 类添加到我的代码时，我遇到了同样的问题。我已经将 tree20 包含到我的具有可靠性类的项目中。所以当我再次将可靠性类添加到我的类时，我得到了同样的错误。我从我的项目中删除了可靠性代码，它工作得很好。
