一个页面显示两个tableview，并且每个tableview上的数据都不一样，一般用以下方法：
首先建一个继承自UIView的类，来表示用来切换tableview的view
//在view的类的.h文件中
#import <UIKit/UIKit.h>
@protocol MyAttentionHeadViewDelegate <NSObject> //建一个叫MyAttentionHeadViewDelegate的一个代理
@optional //两个代理方法(可选择实现optional)
-(void)myAttentionHeadViewLeftBtnClicked:(UIButton*)btn;
-(void)myAttentionHeadViewRightBtnClicked:(UIButton*)btn;
@end
@interface MyAttentionHeadView : UIView
@property (nonatomic,strong) UIButton *leftBtn; //定义左侧按钮
@property (nonatomic,strong) UIButton *rightBtn; //定义右侧按钮
@property (nonatomic,strong) UIView *colorView; //定义按钮下方颜色条
@property (nonatomic,assign) id<MyAttentionHeadViewDelegate>delegate; //代理者
@end
//在view的类的.m文件中
#import "MyAttentionHeadView.h"
@implementation MyAttentionHeadView
//initWithFrame方法用来初始化并返回一个新的视图对象,根据指定的CGRect（尺寸）
-(id)initWithFrame:(CGRect)frame{
self =[super initWithFrame:frame];
if (self) {
self.backgroundColor =[UIColor whiteColor]; //设置view的背景颜色
_colorView =[[UIView alloc]init]; //创建按钮下方颜色条
_colorView.frame =CGRectMake(self.frame.size.width/2.0, self.frame.size.height-1.0, self.frame.size.width/2.0, 1.0);
_colorView.backgroundColor =[UIColor greenColor];
[self addSubview:_colorView]; //将颜色条加入到view中
_leftBtn =[UIButton buttonWithType:UIButtonTypeCustom]; //创建左侧按钮
[_leftBtn setTitle:@"关注的采购商" forState: UIControlStateNormal]; //设置按钮上的文字
[_leftBtn setTitleColor:[UIColor grayColor] forState:UIControlStateNormal]; //设置未选择状态下文字颜色
[_leftBtn setTitleColor:[UIColor greenColor] forState:UIControlStateSelected]; //设置选择状态下文字颜色
_leftBtn.titleLabel.font =[UIFont systemFontOfSize:15.0f]; //设置文字大小
_leftBtn.frame =CGRectMake(0, 0, self.frame.size.width/2.0, self.frame.size.height-1.0); //设置按钮的frame
[_leftBtn addTarget:self action:@selector(leftBtnClicked:) forControlEvents:UIControlEventTouchUpInside];
//为按钮添加点击事件
_leftBtn.backgroundColor =[UIColor whiteColor];//设置按钮背景色
[self addSubview:_leftBtn]; //将按钮添加到view中
_rightBtn =[UIButton buttonWithType:UIButtonTypeCustom];
_rightBtn.frame =CGRectMake(self.frame.size.width/2.0, 0, self.frame.size.width/2.0, self.frame.size.height-1.0);
_rightBtn.backgroundColor =[UIColor whiteColor];
[_rightBtn setTitle:@"关注的农场" forState:UIControlStateNormal];
[_rightBtn setTitleColor:[UIColor grayColor] forState:UIControlStateNormal];
[_rightBtn setTitleColor:[UIColor greenColor] forState:UIControlStateSelected];
_rightBtn.titleLabel.font =[UIFont systemFontOfSize:15.0f];
[_rightBtn addTarget:self action:@selector(rightBtnClicked:) forControlEvents:UIControlEventTouchUpInside];
[self addSubview:_rightBtn];
}
return self;
}
//点击左侧按钮事件
-(void)leftBtnClicked:(UIButton*)btn{
_leftBtn.selected =YES; //左侧按钮选中状态
_rightBtn.selected =NO;//右侧按钮非选中状态
//点击按钮后的动画设置
[UIView animateWithDuration:0.2f animations:^{
_colorView.frame =CGRectMake(0, self.frame.size.height-1.0, self.frame.size.width/2.0, 1.0);
//颜色条在左侧按钮下方
}];
//如果存在叫myAttentionHeadViewLeftBtnClicked:的方法，那么调用这个方法
if ([_delegate respondsToSelector:@selector(myAttentionHeadViewLeftBtnClicked:)]) {
[_delegate myAttentionHeadViewLeftBtnClicked:btn];
}
}
//点击右侧按钮事件
-(void)rightBtnClicked:(UIButton*)btn{
_leftBtn.selected =NO;
_rightBtn.selected =YES;
[UIView animateWithDuration:0.2f animations:^{

}];

}
}
@end
//在controller类的.m文件中导入view类的头文件
@interface MyAttentionViewController ()<UITableViewDataSource,UITableViewDelegate,MyAttentionHeadViewDelegate>
//遵从tableview的两个代理和在view类的自定义代理
