TableView not reloading properly - objective-c

Question

I am making an settings screen in which you can select stations via a uisearchbar. I have a sectioned tableview, with the first letter of a station as the header and every station is categorized by it's first letter. So far so good.
I habe 2 NSMutableArray's with, per section, the stations. One is the unfiltered array (Which I use when I don't have it filtered) and the other one, when I am searching for something. (I do this via a predicate). On every keypress on the keyboard I do a [self.tableView reloadData]; this works, HOWEVER the scrollview stays too long! So you can scroll way past how many results are actually in the selected array. This causes a crash, because it's trying to get objects that don't exist.
So it seems like the tableview isn't counting the array right or something?
Is anyone familiar with this problem?
Here is some code:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
if (self.searching) {
return [self.tableFilterd count];
} else {
return [self.tableData count];
}
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
NSLog(#"Rows for section");
// Return the number of rows in the section.
if (self.searching) {
NSLog(#"Editing section: %i, count %i", section, [[self.tableFilterd objectAtIndex:section] count]);
return [[self.tableFilterd objectAtIndex:section] count];
} else {
NSLog(#"Not editing");
return [[self.tableData objectAtIndex:section] count];
}
}
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
SettingsHeaderCell *cell = [[[SettingsHeaderCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"HeaderCell"] autorelease];
cell.labelLetter.text = [[self.tableLetters objectAtIndex:section] capitalizedString];
return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
return 40;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
return 52;
}
- (UITableViewCell *)tableView:(UITableView *)theTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
SettingsCell *cell = [theTableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[SettingsCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
if (self.searching) {
StationObject *object = (StationObject *)[[self.tableFilterd objectAtIndex:indexPath.section] objectAtIndex:indexPath.row];
[cell setStationObject:object];
} else {
StationObject *object = (StationObject *)[[self.tableData objectAtIndex:indexPath.section] objectAtIndex:indexPath.row];
[cell setStationObject:object];
}
return cell;
}

You might have solved this by now but I suspect you aren't emptying either arrays. In the method:
- (void)searchBar:(UISearchBar *)theSearchBar textDidChange:(NSString *)searchText
{
//Remove all objects first
[self.tableFiltered removeAllObjects];
[self.tableData removeAllObjects];
Also you only need to call [self.tableView reloadData]; in textDidChange, not in the other three methods. Hope this helps.
