*Update: This actually works, the style for my custom cell hasn't come across and so the cell looks blank. How then do I get the searchResultsTableView to use my custom cell?
I have implemented a search bar in my table view. Searching, filtering all work when I debug, but when I enter characters into the search bar, the results do not load or show. This is everything I'm doing:
@interface InviteTableViewController ()<UIAlertViewDelegate, UISearchBarDelegate, UISearchDisplayDelegate> @property(nonatomic, strong) NSNumber *contactsCount; @property(nonatomic, strong) InviteTableViewCell *selectedCell; @property(strong, nonatomic) NSMutableArray *filteredContactArray; @property (weak, nonatomic) IBOutlet UISearchBar *contactsSearchBar; @end @implementation InviteTableViewController - (id)initWithStyle:(UITableViewStyle)style { self = [super initWithStyle:style]; if (self) { // Custom initialization } return self; } - (void) extractAllContacts: (ABAddressBookRef) addressBookRef{ NSMutableArray *contactsArray = [NSMutableArray array]; CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBookRef); CFIndex numberOfPeople = ABAddressBookGetPersonCount(addressBookRef); for(int i = 0; i < numberOfPeople; i++){ ABRecordRef person = CFArrayGetValueAtIndex( allPeople, i ); NSString *firstName = (__bridge NSString *)(ABRecordCopyValue(person, kABPersonFirstNameProperty)); if(firstName){ ABMultiValueRef emails = ABRecordCopyValue(person, kABPersonEmailProperty); for (CFIndex i = 0; i < ABMultiValueGetCount(emails); i++) { NSString *email = (__bridge_transfer NSString *) ABMultiValueCopyValueAtIndex(emails, i); MyUser *amUser = [[MyUser alloc] init]; amUser.email =email; NSString *fullName =[NSString stringWithFormat:@"%@ %@",firstName, (__bridge NSString *)(ABRecordCopyValue(person, kABPersonLastNameProperty))]; amUser.fullName = fullName; [contactsArray addObject:amUser]; } } } NSLog(@"================================count ============= %d", [contactsArray count]); contactsArray = [contactsArray sortedArrayUsingComparator:^NSComparisonResult(id a, id b) { NSDate *first = [(MyUser*) a fullName]; NSDate *second = [(MyUser*)b fullName]; return [first compare:second]; }]; self.inviteContactsArray = contactsArray; self.filteredContactArray = [NSMutableArray arrayWithCapacity:[contactsArray count]]; [self.tableView reloadData]; } - (void)viewDidLoad { [super viewDidLoad]; _contactsCount = [NSNumber numberWithInt:0]; ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, NULL); if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined) { ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) { if (granted) { [self extractAllContacts: addressBookRef]; [self.tableView reloadData]; } else { NSString *message = [NSString stringWithFormat:@"You have not given permission to use your address book. Please allow in settings "]; UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"Enable Contacts" message:message delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; } }); } else if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) { // The user has previously given access, add the contact [self extractAllContacts:addressBookRef]; } else { // The user has previously denied access // Send an alert telling user to change privacy setting in settings app } [self.tableView reloadData]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } #pragma mark - Table view data source - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { // Return the number of sections. return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { if (tableView == self.searchDisplayController.searchResultsTableView) { return [self.filteredContactArray count]; } else { return [self.inviteContactsArray count]; } } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"InviteCell"; InviteTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if ( cell == nil ) { cell = [[InviteTableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier]; } MyUser *person = nil; if (tableView == self.searchDisplayController.searchResultsTableView) { person = [self.filteredContactArray objectAtIndex:[indexPath row]]; NSMutableArray *tempArray = self.filteredContactArray; } else { person = [self.inviteContactsArray objectAtIndex:[indexPath row]]; } //InviteTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; person = [self.inviteContactsArray objectAtIndex:indexPath.row]; cell.nameLabel.text = person.fullName; cell.emailLabel.text = person.email; return cell; } #pragma mark Content Filtering -(void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope { // Update the filtered array based on the search text and scope. // Remove all objects from the filtered search array [self.filteredContactArray removeAllObjects]; // Filter the array using NSPredicate NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF.fullName contains[c] %@",searchText]; self.filteredContactArray = [NSMutableArray arrayWithArray:[self.inviteContactsArray filteredArrayUsingPredicate:predicate]]; } #pragma mark - UISearchDisplayController Delegate Methods -(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString { [self filterContentForSearchText:searchString scope:[[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:[self.searchDisplayController.searchBar selectedScopeButtonIndex]]]; return YES; } @end This is what it looks like:
