Is it possible to make uitableheader passes just over the first tablecell? - iphone

Question

i have a simple uitableview with tableHeaderView. i have more than one section.
i set the headerview's height 30. but i want to use 40 pixel height uiview in my header (from 0,0 to 320,30 not transparent. from 30,10 to 320,40 is transparent). i put a picture in it. there is a small icon on point(0x30). its height=10.
i just want to show my headerview just a little bit over on the first tablecell.
you will see below that i set header's height to 30, but i create 40 pixel height view in viewForHeaderInSection.
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
return 30;
}
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
UIView *sectionView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 40)];
sectionView.backgroundColor = [UIColor redColor];
[sectionView autorelease];
return sectionView;
}
is it possible?

Answer 1

Your sectionView will be limited by the height of header. Even if you use a UIView of 1000 pixels high, it will only be shown within the limits defined by the height of a table cell/header.

Answer 2

Maybe I have an answer for your problem. I don't know if this is a good solution but I think it is okay.
I made a new empty xib file and put a UITableViewCell in that file. I changed the height of the UITableViewCell to 54 and put a UIView inside the UITableViewCell. The frame of the view is 0,0,320,10. Then I changed the file's owner of that xib file to my TableViewController.
#interface RootViewController : UITableViewController {
UITableViewCell * firstCellInSection;
}
#property (nonatomic, retain) IBOutlet UITableViewCell * firstCellInSection;
#end
After that I connected the firstCellInSection Outlet with my UITableViewCell in the xib file.
Then I changed the code that the TableView loads this firstCell for all cells with
indexPath.row == 0
Here is the code:
#synthesize firstCellInSection;
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell * cell;
if (indexPath.row == 0) {
if (indexPath.row == 0) {
static NSString *firstCellInSectionIdentifier = #"FirstCellInSectionIdentifier";
cell = [tableView dequeueReusableCellWithIdentifier:firstCellInSectionIdentifier];
if (cell == nil) {
[[NSBundle mainBundle] loadNibNamed:#"FirstCell" owner:self options:nil];
cell = firstCellInSection;
self.firstCellInSection = nil;
}
}
}
else {
static NSString *CellIdentifier = #"Cell";
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
}
// Configure the cell.
return cell;
}
Custom row height:
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
if (indexPath.row == 0) return 54;
else return 44;
}
In combination with your code for the headerView it could look like you want.
