Objective-C：typedef NS_ENUM错误

我在iOS应用程序中使用了typedef NS_ENUM，并且出现此错误：“linker command failed failed with exit code 1”。通常，这就是很容易解决，但这次我不能找到解决办法......Objective-C：typedef NS_ENUM错误

这是我NS_Enum：

typedef NS_ENUM(NSInteger, MKIGridViewSelectionStyle) 
      MKIGridViewSelectionStyle_SelectCellOnly = 1, 
      MKIGridViewSelectionStyle_SelectCompleteRow = 2, 
      MKIGridViewSelectionStyle_SelectCompleteColumn = 3;

你会需要修改你的问题在连接器输出进行粘贴。要找到它，请选择“视图”>“导航器”>“显示日志导航器”。然后点击日志导航器中最上面的“Build * YourTarget *”行。然后查看日志并找到链接器输出。 –

您忘记在值定义周围使用大括号。

typedef NS_ENUM(NSInteger, MKIGridViewSelectionStyle) { 
     MKIGridViewSelectionStyle_SelectCellOnly = 1, 
     MKIGridViewSelectionStyle_SelectCompleteRow = 2, 
     MKIGridViewSelectionStyle_SelectCompleteColumn = 3 
};

啊，好的，谢谢！ – Maik639

还要确保“typedef”在那里，没有它你也可以看到类似的重复符号错误。 – MikecheckDev
