其中

typedef enum {
    RoleUnknown,
    RoleStudent,//1 学员
    RoleMajia,// 2 马甲
    RoleOfficial,//  3 官方
    RoleTeacher// 4 老师
} Role;

@property (nonatomic,assign)Role role;

深得我心

@property (nonatomic,assign,getter = isLike)BOOL is_like;

is_like 是后端小伙伴定义的字段，为了让代码更符合Objective-C的编码习惯，添加getter = isLike即可,在使用的地方可以isLike
因为，getter,属于点方法，并不是属性property,
所以，你只能获取isLike,无法为isLike赋值
