UISearchDisplayController display custom UITableViewCell when No Results - ios

Question

I have one UITableView consisting of some custom UITableViewCells and one UISearchDisplayController connected to it. How can I show another custom Table View Cell if there are no results when you search for something?
Here's how the search and table view functions look like:
- (void)searchTableList:(UISearchBar*)searchBar {
NSString *searchString = searchBar.text;
for (NSArray *section in _celebs)
for (NSDictionary *row in section) {
if ([[row[#"name"] lowercaseString] rangeOfString:[searchString lowercaseString]].location!=NSNotFound)
[filteredContentList addObject:row];
}
}
- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar {
isSearching = YES;
}
- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText {
[filteredContentList removeAllObjects];
if (searchText.length) {
isSearching = YES;
[self searchTableList:searchBar];
} else isSearching = NO;
}
- (void)searchDisplayControllerDidEndSearch:(UISearchDisplayController *)controller{
}
- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar {
isSearching = NO;
}
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar {
[self searchTableList:searchBar];
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return [tableView isEqual:self.searchDisplayController.searchResultsTableView]?1:_objects.count;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [tableView isEqual:self.searchDisplayController.searchResultsTableView]?filteredContentList.count:[_objects[section] count];
}
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
return [tableView isEqual:self.searchDisplayController.searchResultsTableView]?0:25;
}
- (CGFloat)tableView:(UITableView *)tableView estimatedHeightForHeaderInSection:(NSInteger)section {
return [self tableView:tableView heightForHeaderInSection:section];
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
return 55;
}
- (CGFloat)tableView:(UITableView *)tableView estimatedHeightForRowAtIndexPath:(NSIndexPath *)indexPath {
return [self tableView:tableView heightForRowAtIndexPath:indexPath];
}
- (NSDictionary *)getObjectFromIndexPath:(NSIndexPath*)indexPath tableView:(UITableView*)tableView {
BOOL search = [tableView isEqual:self.searchDisplayController.searchResultsTableView];
if (search)
return indexPath.row<filteredContentList.count?filteredContentList[indexPath.row]:nil;
else return indexPath.section<_objects.count?
(indexPath.row<[_objects[indexPath.section] count]?_objects[indexPath.section][indexPath.row]:nil)
:nil;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
BOOL search = [tableView isEqual:self.searchDisplayController.searchResultsTableView];
FirstTableViewCell *cell;
NoResultsTableViewCell *cell1;
if (tableView == self.searchDisplayController.searchResultsTableView) {
cell = (FirstTableViewCell*)[self.tableView dequeueReusableCellWithIdentifier:#"FirstTableViewCell"];
} else {
cell = (FirstTableViewCell*)[self.tableView dequeueReusableCellWithIdentifier:#"FirstTableViewCell" forIndexPath:indexPath];
}
NSDictionary *object = [self getObjectFromIndexPath:indexPath tableView:tableView];
if (!object) return cell;
cell.object = celeb;
cell.objectName.text = [object objectForKey:#"name"];
}
}
return cell;
}

Make some changes like below:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if ([tableView isEqual:self.searchDisplayController.searchResultsTableView]){
if (filteredContentList.count > 0){
return filteredContentList.count;
}else{
return 1; // the number of custom cells when there're no results
}
}else{
return [_objects[section] count];
}
}
- (NSDictionary *)getObjectFromIndexPath:(NSIndexPath*)indexPath tableView:(UITableView*)tableView {
BOOL search = [tableView isEqual:self.searchDisplayController.searchResultsTableView];
if (search)
return indexPath.row < filteredContentList.count? filteredContentList[indexPath.row]: theCustomCellDict; // use theCustomCellDict instead of nil
else return indexPath.section < _objects.count?
(indexPath.row < [_objects[indexPath.section] count]? _objects[indexPath.section][indexPath.row]: nil)
:nil;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
BOOL isSearch = [tableView isEqual:self.searchDisplayController.searchResultsTableView];
FirstTableViewCell *cell;
NoResultsTableViewCell *noReultsCell;
if ((isSearch && filteredContentList.count > 0) || !isSearch){
cell = (FirstTableViewCell *)[self.tableView dequeueReusableCellWithIdentifier:#"FirstTableViewCell" forIndexPath:indexPath];
NSDictionary *object = [self getObjectFromIndexPath:indexPath tableView:tableView];
if (!object) return cell;
cell.object = celeb;
cell.objectName.text = [object objectForKey:#"name"];
return cell;
}else{
noResultsCell = (NoResultsTableViewCell *)[self.tableView dequeueReusableCellWithIdentifier:#"NoResultsTableViewCell" forIndexPath:indexPath];
NSDictionary *object = [self getObjectFromIndexPath:indexPath tableView:tableView];
if (!object) return noResultsCell;
noResultsCell.object = celeb;
noResultsCell.objectName.text = [object objectForKey:#"name"];
return noResultsCell
}
}

If you want to just show information (for example there is no result found 'something' ) You don't need to use UITableViewCells. I will reccomend you to look DZNEmptyDataSet library.
