UITableView resize header for section does not stretch according to its size

Question

i have a table view which has header for the tableview and another header for section. the header for section has a button on top of it, when the button is pressed i need to change the size of this header.

i did changed the header size but the content within it does not change accordingly.

i even fixed it using this-

_isHeaderExtended = !_isHeaderExtended;
[self.testTable beginUpdates];
CGPoint point = testTable.contentOffset;
point.y = (_isHeaderExtended)? point.y - 1: point.y + 1;

[testTable setContentOffset:point animated:NO];
[self.testTable endUpdates];

my entire code is below

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{

    return 30;
}

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

    return testView;
}
-(CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {

    [self.testTable beginUpdates];
    CGFloat fl = (_isHeaderExtended)?200:100;
    [self.testTable endUpdates];

    return fl;
}

-(IBAction)buttonPushed:(id)sender {
    _isHeaderExtended = !_isHeaderExtended;

    [self.testTable beginUpdates];
    CGPoint point = testTable.contentOffset;
    point.y = (_isHeaderExtended)? point.y - 1: point.y + 1;

    [testTable setContentOffset:point animated:NO];
    [self.testTable endUpdates];


}

basically i need the content of the header to stretch according to the resize i use, any ideas ???

Answer 1

I think it should be changed into:

-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
    if( _isHeaderExtended ){
        return bigTestView;
    } else {
        return smallTestView;
    }
}

-(CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
    return _isHeaderExtended?200:100;
}

-(IBAction)buttonPushed:(id)sender {
    _isHeaderExtended = !_isHeaderExtended;
    [self.testTable reloadData];
}

Then you need to create a bigTestView and a smallTestView for the header.
