我在 iOS 应用程序中使用 typedef NS_ENUM 并收到此错误：“链接器命令失败，退出代码 1”。通常这很容易解决，但这次我找不到解决方案......

这是我的 NS_Enum：

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

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
};
