ScrowView具体用法

//UIView:
-(id)initWithFrame:(CGRect)frameid)targetSEL)sel
{
    self=[super initWithFrame:frame];
    if (self)
    {
        controller=target; //传一个id类型的controller
        [self creatScrow];
        f_tableA=[self creatTableA]; //f_ 表示设置为全局变量
        f_tableB=[self creatTableB];
    }
    return self;
}


-(void)creatScrow
{
    scrow=[[UIScrollView alloc]initWithFrame:CGRectMake(0, 30, self.frame.size.width, self.frame.size.height-50)];
        scrow.directionalLockEnabled=YES;//只能一个方向滑动
        scrow.pagingEnabled = YES; //是否翻页
        scrow.backgroundColor = [UIColor blackColor];
        scrow.showsVerticalScrollIndicator =NO; //垂直方向的滚动指示
        scrow.indicatorStyle = UIScrollViewIndicatorStyleWhite;//滚动指示的风格
        scrow.showsHorizontalScrollIndicator = YES;//水平方向的滚动指示
        CGSize size=CGSizeMake(self.frame.size.width * 2, 0);
        [scrow setContentSize:size];
    [self addSubview:scrow];
   [self creatTableA];
   [self creatTableB];
}


-(id)creatTableA
{
    UITableView *tableA=[[UITableView alloc]initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, self.frame.size.height) style:UITableViewStylePlain];
    tableA.delegate=controller;//设置代理方法
    tableA.dataSource=controller;
    tableA.backgroundColor = [UIColor blueColor];
    [scrow addSubview:tableA];
    return tableA;
}

-(id)creatTableB
{
    UITableView *tableB=[[UITableView alloc]initWithFrame:CGRectMake(self.frame.size.width, 0, self.frame.size.width, self.frame.size.height) style:UITableViewStylePlain];
    tableB.delegate=controller;//设置代理方法
    tableB.dataSource=controller;
    tableB.backgroundColor = [UIColor greenColor];
    [scrow addSubview:tableB];
    return tableB;
}

//UIViewController:
//在代理方法中的写法
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (tableView==scrowView.f_tableA)
{
}
if (tableView==scrowView.f_tableB)
{
}
}
