UISearch not showing results - iphone

Question

I'm querying from parse and I when I try to search using the search bar it returns with "no results." I'm trying to figure out what I did wrong showing the objects because it does show in the NSLog that it has found objects.
My viewDidLoad:
- (void)viewDidLoad
{
[super viewDidLoad];
self.searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 44)];
self.tableView.tableHeaderView = self.searchBar;
self.searchController = [[UISearchDisplayController alloc] initWithSearchBar:self.searchBar contentsController:self];
self.searchController.searchResultsDataSource = self;
self.searchController.searchResultsDelegate = self;
self.searchController.delegate = self;
self.searchResults = [NSMutableArray array];
// Uncomment the following line to preserve selection between presentations.
// self.clearsSelectionOnViewWillAppear = NO;
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem;
}
The Retrieving for the Table View:
-(void)filterResults:(NSString *)searchTerm {
[self.searchResults removeAllObjects];
PFQuery *query = [PFQuery queryWithClassName:#"New"];
[query whereKeyExists:#"title"]; //this is based on whatever query you are trying to accomplish
[query whereKey:#"title" containsString:searchTerm];
NSArray *results = [query findObjects];
NSLog(#"%u", results.count);
[self.searchResults addObjectsFromArray:results];
}
Finally, The tableview cell that doesn't want to work:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
PFObject * testObject = [self.searchResults objectAtIndex:indexPath.row];
cell.textLabel.text = [testObject objectForKey:#"title"];
return cell;
}
Then:
-(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString {
[self filterResults:searchString];
return YES;
}
Then to load from Parse to UTTableview:
- (id)initWithCoder:(NSCoder *)aDecoder
{
self = [super initWithClassName:#"New"];
self = [super initWithCoder:aDecoder];
if (self) {
// The className to query on
self.ClassName = #"New";
//self.textKey = #"title";
// The key of the PFObject to display in the label of the default cell style
// self.keyToDisplay = #"text";
// Whether the built-in pull-to-refresh is enabled
self.pullToRefreshEnabled = NO;
// Whether the built-in pagination is enabled
self.paginationEnabled = YES;
self.loadingViewEnabled = NO;
// The number of objects to show per page
self.objectsPerPage = 50;
}
return self;
}

You can use another way where you can take the help of the search bar delegate method.
e.g - Include UISearchBarDelegate in your header file and also -
#property (strong, nonatomic) IBOutlet UISearchBar *searchSong;
Now in your .m file
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
{
NSMutableArray *temp = [[NSMutableArray alloc] init];
temp = [self searchSongsData:self.searchSong.text from:`YourArray`];
}
+ (NSMutableArray *) searchSongsData:(NSString *)searchtext from:(NSMutableArray *)array
{
NSMutableArray *arrayToBeReturned = [[NSMutableArray alloc] init];
NSArray *temp = [[NSArray alloc] initWithArray:array];
NSString *textToBeSearch = [searchtext lowercaseString];
SongsMoviesData *songs;
for(int i = 0; i<temp.count; i++)
{
songs = [temp objectAtIndex:i];
NSString *string1 = [songs.song_title lowercaseString];
NSString *string2 = [songs.moview_name lowercaseString];
NSString *string3 = [songs.singer_name lowercaseString];
if ([string1 rangeOfString:textToBeSearch].location != NSNotFound ||[string2 rangeOfString:textToBeSearch].location != NSNotFound || [string3 rangeOfString:textToBeSearch].location != NSNotFound)
{
// NSLog(#"%#", songs.moview_name);
[arrayToBeReturned addObject:songs];
}
}
return arrayToBeReturned;
}
and like this you save this array in your search results.
