首先，讲解一下本次为大家分享的主要内容 在tablecell中实现点菜功能，具体功能如下
viewcontroll
.h
@property(nonatomic,strong)UILabel *theNameLab;
@property(nonatomic,strong)UILabel *theNumLab;
.m
{
NSMutableArray *data;
int num;//总价格
UITableView *NameTable;

}

.h定义属性
@property(nonatomic,strong)UIImageView *theImage;
@property(nonatomic,strong)UILabel *theLab;

.m实现
