Question

My application has a header (like toolbar) which contains some button controllers,and just below the header view there is a tableview which contains some datas from sqlite.

When the tableview starts scrolling, I need the top header to hide and another header to pop out in place of the main header view.

Is it possible to this? But I didnt want this in a tap function.

- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
    if(scrollView == table)
    {
        tab.contentOffset = table.contentOffset; 
        headerview.hidden=YES;
    }
    else
    {
        table.contentOffset = tab.contentOffset;
        headerview.hidden=YES;
    }
}

it hides the headerview ,but my problem is when the scrolling of tableview stops headerview need to be appear again.

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{
    NSLog(@"scrollViewDidEndDecelerating");
    if(scrollView == table)
    {
        tab.contentOffset = table.contentOffset; 
        headerview.hidden=NO;

    }
    else
    {
        table.contentOffset = tab.contentOffset;
        headerview.hidden=NO;

    }
}

when the scroling stops it

- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
    if(scrollView == table)
    {
        tab.contentOffset = table.contentOffset; 
        headerview.hidden=YES;
    }
    else
    {
        table.contentOffset = tab.contentOffset;
        headerview.hidden=YES;
    }
}

it hidses the header view.
thankyou.
