iOS中tableview中headerview总保持在屏幕上方和随着屏幕滑动一起移动至消失

1 : tableview中headerview总保持在屏幕上方 :  在代理方法中创建view,并添加到headerview上

l例子:

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section

{

    if ([self.title isEqualToString:@"幕后"]) {

        NSArray *array = @[@"全部",@"电影自习室",@"电影会客厅",@"拍摄",@"综述",@"后期",@"器材"];

        UIScrollView *scroller = [[UIScrollView alloc] init];

        scroller.contentSize = CGSizeMake(560, 30);

        scroller.backgroundColor = [UIColor whiteColor];

        scroller.showsHorizontalScrollIndicator = NO;

        UISegmentedControl *segment = [[UISegmentedControl alloc] initWithItems:array];

        segment.tintColor = [UIColor lightGrayColor];

        [[UISegmentedControl appearance] setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor blackColor]} forState:UIControlStateSelected];

        [scroller addSubview:segment];

        return scroller;

       

    }

    return nil;

}

2 : 想随着屏幕滑动一起移动至消失的话: 就直接调用属性方法,将创建的view指定到headerview的试图()

l例子: {在viewdidload中}

  self.headerView = [[HeaderView alloc] initWithFrame:CGRectMake(0, 0, 320, 150)];

        self.tableView.tableHeaderView = self.headerView;
