Question

I hope to fold the tableview cell , when I tap the red button

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    if([[appDelegate.gHomeHeaderArray_AppDelegate objectAtIndex:section] getIsFolded]==true)      
    {       
        return 0;           
    }
    else
    {
       return 1;      
    }
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    if([[appDelegate.gHomeHeaderArray_AppDelegate objectAtIndex:section] getIsFolded ]==true)
    {   
       return 0;

    }
    else
    {
        return 1; 
    }
}

-(void)buttonTapped:(id)sender;
{
    if([[appDelegate.gHomeHeaderArray_AppDelegate objectAtIndex:v] getIsFolded])
    {
         [[appDelegate.gHomeHeaderArray_AppDelegate objectAtIndex:v] setIsFolded:false];
    }
    else
    {
        [[appDelegate.gHomeHeaderArray_AppDelegate objectAtIndex:v] setIsFolded:true];
    }
    [listview reloadData];
}

When I tape a button, it will check if set the numberOfRowsInSection to 0

it works, but the tableview cell move to under another header view rather than hiding.

Welcome any comment
