Question

我在iOS-App中使用了typedef NS_ENUM，我收到此错误：“链接器命令失败，退出代码为1”。通常这很容易修复，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
};

Objective-C：typedef NS_ENUM错误
