UISearchView not displaying search values - iphone

Question

In my TableView which Expands on the clicking on the sections.now I am using Uisearchbar to search the sections in the table...It gives me the UIsearchbar but Search cannot be taken...
I think problem is in the numberOfRowsInSection.please check where I am getting wrong..
why searchbar is not working
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return [self.mySections count];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
NSInteger rows = 0;
if ([self tableView:tableView canCollapseSection:section] || (tableView == self.searchDisplayController.searchResultsTableView) )
{
if ([expandedSections containsIndex:section] )
{
NSString *key = [self.mySections objectAtIndex:section];
NSArray *dataInSection = [[self.myData objectForKey:key] objectAtIndex:0];
return [dataInSection count];
}
return 1;
} else{
rows = [self.searchResults count];
return rows;
}
return 1;
}
-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection: (NSInteger)section {
NSString *key = [self.mySections objectAtIndex:section];
return [NSString stringWithFormat:#"%#", key];
}
- (void)filterContentForSearchText:(NSString*)searchText
scope:(NSString*)scope
{
NSPredicate *resultPredicate = [NSPredicate
predicateWithFormat:#"SELF contains[cd] %#",
searchText];
self.searchResults = [self.allItems filteredArrayUsingPredicate:resultPredicate];
}
-(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{
UISearchBar * searchBar = [controller searchBar];
[self filterContentForSearchText:searchString scope:[[searchBar scopeButtonTitles] objectAtIndex:[searchBar selectedScopeButtonIndex]]];
return YES;
}
-(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchScope:(NSInteger)searchOption
{
UISearchBar * searchBar = [controller searchBar];
[self filterContentForSearchText:[searchBar text] scope:[[searchBar scopeButtonTitles] objectAtIndex:searchOption]];
return YES;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] ;
}
// Configure the cell...
if ([tableView isEqual:self.searchDisplayController.searchResultsTableView]) {
cell.textLabel.text = [self.searchResults objectAtIndex:indexPath.row];
}else {
NSUInteger section = [indexPath section];
NSUInteger row = [indexPath row];
NSString *key = [self.mySections objectAtIndex:section];
NSDictionary *dataForSection = [[self.myData objectForKey:key] objectAtIndex:0];
NSArray *array=dataForSection.allKeys;
cell.textLabel.text = [[dataForSection allKeys] objectAtIndex:row];
cell.detailTextLabel.text=[dataForSection valueForKey:[array objectAtIndex:indexPath.row]];
}
return cell;
}

You are not reloading your table after searching
- (void)filterContentForSearchText:(NSString*)searchText
scope:(NSString*)scope
{
NSPredicate *resultPredicate = [NSPredicate
predicateWithFormat:#"SELF contains[cd] %#",
searchText];
self.mySections = [self.mySections filteredArrayUsingPredicate:resultPredicate];
[myTableView reloadData];
}
Edit
Your are not setting detail text label
if ([tableView isEqual:self.searchDisplayController.searchResultsTableView])
{
cell.textLabel.text = [self.searchResults objectAtIndex:indexPath.row];
cell.detailTextLabel.text=[dataForSection valueForKey:[self.searchResults objectAtIndex:indexPath.row]];
}
and after searching you are getting title now row because in your code
rows = [self.searchResults count];
return rows;
its always returning zero value. So just do it return 1;
And do other thing as your requirement,
And i will suggest you to not to use different different code for before table search and after searching.. Like if ([tableView isEqual:self.searchDisplayController.searchResultsTableView])
just use same code for both..and make changes only in array and dictionary..
initially
tableAry = globalAry;
And after searching
tableAry = searchedAry;
