UiscrollView 简单使用

示例代码如下：

    UIScrollView *scrView = [[UIScrollView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width , self.view.frame.size.height)];
    scrView.scrollEnabled = YES;
    scrView.contentSize = CGSizeMake(self.view.frame.size.width*3,self.view.frame.size.height);
    scrView.backgroundColor = [UIColor lightGrayColor];
    [self.view addSubview:scrView];
    
    UIImageView *imgView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, scrView.frame.size.height)];
    [scrView addSubview:imgView];
    UIImageView *imgView2 = [[UIImageView alloc]initWithFrame:CGRectMake(self.view.frame.size.width, 0, scrView.frame.size.width, scrView.frame.size.height)];
    [scrView addSubview:imgView2];
    UIImageView *imgView3 = [[UIImageView alloc]initWithFrame:CGRectMake(self.view.frame.size.width*2, 0, scrView.frame.size.width, scrView.frame.size.height)];
    [scrView addSubview:imgView3];
    
    imgView.image = [UIImage imageNamed:@"1"];
    imgView2.image = [UIImage imageNamed:@"2"];
    imgView3.image = [UIImage imageNamed:@"3"];
