要求：在一个view中显示两个tableView，要求左右显示的内容以及行数不一样，且左边每行显示两张图片（分别3个一轮回，2个一轮回）并且显示中国的城市名，右边显示水果名。点击时分别显示城市名或水果名的对话框（偶数的城市不能点击）（所选的图片长短比例不一致）
运行图：
步骤：
1.创建一个tableCell.xib
2.viewController.h:
#import <UIKit/UIKit.h> @interface DXWViewController : UIViewController<UITableViewDataSource,UITableViewDelegate> @property (retain, nonatomic) IBOutlet UITableViewCell *ccell; @end
3.viewController.m:
//
// DXWViewController.m
// 两个tableView
