Search Results not visible - iphone

Question

I have a table view with a search display controller. When I type a search the log shows me the search is working and filtering properly however the screen only shows "No Results". I'm using Core Data if that makes a difference.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
if (tableView == self.searchDisplayController.searchResultsTableView) {
return [searchResults count];
}
else{
return[[self.fetchedResultsController sections]count];
}
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
id <NSFetchedResultsSectionInfo> secInfo = [[self.fetchedResultsController sections]objectAtIndex:section];\
return [secInfo numberOfObjects];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell;
static NSString *CellIdentifier = #"Cell";
if (tableView != self.tableView) {
NSLog(#"Found searchDisplayController");
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
} else {
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
NSLog(#"Found regular table View");
}
// Configure the cell...
Instance *instance = [self.fetchedResultsController objectAtIndexPath:indexPath];
if (tableView == self.searchDisplayController.searchResultsTableView) {
cell.textLabel.text = [searchResults objectAtIndex:indexPath.row];
} else {
cell.textLabel.text = instance.name;
}
Here are NumberOfRowsInSection and Number:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
if (tableView == self.searchDisplayController.searchResultsTableView) {
return [searchResults count];
}
else{
return[[self.fetchedResultsController sections]count];
}
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
id <NSFetchedResultsSectionInfo> secInfo = [[self.fetchedResultsController sections]objectAtIndex:section];\
return [secInfo numberOfObjects];
}

Answer 1

Check your implementation of numberOfSectionsInTableView and numberOfRowsInSection.
In the first, you should return 1 if it's the search table view (1 section).
In numberOfRowsInSection you should also check the given tableView argument as you did in numberOfSectionsInTableView and return [searchResults count].

Answer 2

Shouldn't your implementation be something like :-
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
if (tableView == self.searchDisplayController.searchResultsTableView)
{
return 1;
}
else
{
return[[self.fetchedResultsController sections]count];
}
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if(tableView == self.searchDisplayController.searchResultsTableView)
{
return [searchResults count];
}
id <NSFetchedResultsSectionInfo> secInfo = [[self.fetchedResultsController sections]objectAtIndex:section];\
return [secInfo numberOfObjects];
}
If the number of search results is high, then I would suggest using another Fetched Results Controller instead of an array.
