Parse SDK for iOS; Using UISearchBar on UITableView - ios

Question

I'm retrieving data from parse and put it the tableview but when I'm trying to also add a searchbar I don't know how can I manage it. What should I do on tableView:cellForRowAtIndexPath: method instead of NSLog(#"do something!!");
My code is below and thanks for any help.
retrieve from parse code is below
- (void) retrieveFromParse {
PFQuery *retrieveName = [PFQuery queryWithClassName:#"pFihrist"];
[retrieveName findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error) {
nameArray = [[NSMutableArray alloc] initWithArray:objects];
}
[tableView reloadData];
}];
}
UITableView Delegate code is below
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if (self.tableView == self.searchDisplayController.searchResultsTableView) {
return [searchResults count];
} else {
return [nameArray count];
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"fCell";
FihristCell *cell = (FihristCell *)[self.tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[FihristCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
if (tableView == self.tableView) {
PFObject *tempObject = [nameArray objectAtIndex:indexPath.row];
cell.cellProfName.text = [tempObject objectForKey:#"pName"];
} else {
NSLog(#"do something!!");
}
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(#"cell tapped");
}
search methods code is below
- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope
{
NSPredicate *resultPredicate = [NSPredicate predicateWithFormat:#"name contains[c] %#", searchText];
searchResults = [nameArray filteredArrayUsingPredicate:resultPredicate];
}
-(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{
[self filterContentForSearchText:searchString
scope:[[self.searchDisplayController.searchBar scopeButtonTitles]
objectAtIndex:[self.searchDisplayController.searchBar
selectedScopeButtonIndex]]];
return YES;
}

Answer 1

First Register the Cell to display you searched items
You have to register the cell to searchdisplaycontroller as well.
Important: You must register a class or nib file using the registerNib:forCellReuseIdentifier: or registerClass:forCellReuseIdentifier: method before calling this method.
in View did load
If you are Creating cell in code
[self.searchDisplayController.searchResultsTableView registerClass:[TableViewCell class]
forCellReuseIdentifier:#"IdentifierForCell"];
If you are Creating cell in nib
[self.searchDisplayController.searchResultsTableView registerNib:[UINib nibWithNibName:#"CellNibName" bundle:nil]
forCellWithReuseIdentifier:#"IdentifierForCell"];
2. Deque corresponding cell to search display controller table with identifier
FihristCell *cell = (FihristCell *)[self.searchDisplayController.searchResultsTableView dequeueReusableCellWithIdentifier:CellIdentifier];
3. configure that cell to display instead of NSLog
