本文主要是介绍IOS学习 scrollView,pageControl,tableView在同一页面上处理，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
@implementation MainViewController
- (void)viewDidLoad {
[super viewDidLoad];
//设置scrollview
UIScrollView *_scrollView = [[UIScrollView alloc]initWithFrame:CGRectMake(0, 20,VIEW_WIDTH , 261)]; //屏幕宽度
//设置内容大小
_scrollView.contentSize = CGSizeMake(VIEW_WIDTH*4,261);
_scrollView.showsHorizontalScrollIndicator = NO;
_scrollView.delegate = self; //设置代理
_scrollView.pagingEnabled = YES; //分页
//设置图片
for (int i = 0; i<4; i++)
{

//设置图片
NSString *name = [NSString stringWithFormat:@"background%d",i+1];
imageView.image=[UIImage imageNamed:name];
[_scrollView addSubview:imageView];
}
//将滑动视图添加到表视图上
self.tableView.tableHeaderView = _scrollView;

}
#pragma mark - scrollView Delegate

}
else{
//scrollView的偏移量，x,y值
int current = scrollView.contentOffset.x/VIEW_WIDTH;

// NSLog(@"scrollViewDidEndDecelerating %@",scrollView);

#pragma mark - Table view data source
