From the error, I would guess that:
从错误中,我猜:
-
you have two files,
VaultSelectionViewController.mandSetLockViewController.m(the first being originally a copy of the second, probably)你有两个文件,VaultSelectionViewController.m和SetLockViewController.m(第一个原本是第二个的副本,可能)
-
they both contain
@implementation SetLockViewController, and identical properties and/or methods and/or instance variables.它们都包含@implementation SetLockViewController,以及相同的属性和/或方法和/或实例变量。
Solution: fix the class name in the @implementation to match the file name.
解决方案:修复@implementation中的类名以匹配文件名。
If that's not the issue, please provide the relevant parts of both files.
如果这不是问题,请提供两个文件的相关部分。

Make sure your compile sources does not have dup files. (Bad merge can cause this issue.) Remove them and add them again can fix this build error.
确保您的编译源没有dup文件。 (错误合并可能会导致此问题。)删除它们并再次添加它们可以修复此生成错误。

Make sure you does not implement one function twice. (Copy codes and forget to rename the @implement XXX? Or copy and paste one function twice?) Just search the function define in your project and remove the dup one.
确保没有两次实现一个功能。 (复制代码并忘记重命名@implement XXX?或者复制并粘贴一个函数两次?)只需搜索项目中的函数define并删除dup函数。
