多个UITableView横向切换的简单实现（有点类似网易新闻）

实现多列表切换，位置监控，置顶等功能。

方法一：

创建一个TableView，在切换的时候请求各类目需要的数据，然后刷新列表，通过动画模拟出滑动效果。

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController<UITableViewDataSource,UITableViewDelegate,UIScrollViewDelegate>
{
    //选择视图数组
    NSMutableArray *selectArray;
    //选择视图
    UIView *selectView;
    //列表
    UITableView *jiuJiuTableView;
    //选择类型
    NSInteger priceType;
    //切换之前的类型
    NSInteger oldType;
    //数量显示（返回顶部）
    UIView *countView;
    //记录tableview的contentOffset.y
    CGFloat lastY;
    //返回顶部
    UIButton *toTopButton;
    //记录tableview的位置
    NSMutableDictionary *jiLuDictionary;
}
//数据源
@property (nonatomic, strong) NSMutableArray *tableArray;

@end

#import "ViewController.h"
//tableview的cell的高度
#define cellHeight self.view.frame.size.width*0.4
@interface ViewController ()

@end

创建多个TableView，放在ScrollView中，实现横向滑动。（相比性能等方面，推荐使用第一种方法）
