SearchController not searching custom UITableViewCells - ios

Question

Not sure if the title makes to much sense so here is a description of what is going on:
I have a UITableViewController that is using a custom UITableViewCell for its data. I am then manually adding a searchBar to the header of the UITableView and setting it up based on this tutorial : http://useyourloaf.com
Now the searchBar is setup, it looks like it is working but the issue is that I am not actually getting any results and the table is not loading properly (the search results, it load the base data fine)
Here is my code for comparison. I know I must be missing something simple...
** I am hardcoding the data for my cells at the moment, this will change to a core data model once I can fix this issue... although this may be the base of my issue as I am hardcoding the cells at each IP **
#implementation CharitiesTableViewController{
NSArray *charities;
NSArray *searchResults;
}
- (void)viewDidLoad {
[super viewDidLoad];
[self setColors];
[_charityTable registerNib:[UINib nibWithNibName:#"CharityTableViewCell" bundle:[NSBundle mainBundle]] forCellReuseIdentifier:#"charityCell"];
self.tableView.rowHeight = UITableViewAutomaticDimension;
self.tableView.estimatedRowHeight = 350.0;
// self.tableView.contentInset = UIEdgeInsetsMake(-2.0f, 0.0f, 0.0f, 0.0);
self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
self.searchController.searchResultsUpdater = self;
self.searchController.dimsBackgroundDuringPresentation = NO;
self.searchController.searchBar.delegate = self;
self.searchController.delegate = self;
self.tableView.tableHeaderView = self.searchController.searchBar;
self.definesPresentationContext = YES;
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
}
- (void) setColors {
}
#pragma mark - Search Controller
- (void)updateSearchResultsForSearchController:(UISearchController *)searchController {
NSString *searchString = searchController.searchBar.text;
[self searchForText:searchString];
[self.tableView reloadData];
}
- (void)searchForText:(NSString *)searchText {
NSPredicate *resultPredicate = [NSPredicate predicateWithFormat:#"name contains[c] %#", searchText];
searchResults = [charities filteredArrayUsingPredicate:resultPredicate];
}
- (void)willPresentSearchController:(UISearchController *)searchController {
self.navigationController.navigationBar.translucent = YES;
}
-(void)willDismissSearchController:(UISearchController *)searchController {
self.navigationController.navigationBar.translucent = NO;
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
if (tableView == _charityTable)
{
return 1;
}
return [searchResults count];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 1;
}
- (CGFloat)tableView:(UITableView*)tableView heightForHeaderInSection:(NSInteger)section {
return SectionSpacer;
}
- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section {
return SectionSpacer;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
switch (indexPath.section) {
case 0:{
CharityTableViewCell *cell = (CharityTableViewCell *)[tableView dequeueReusableCellWithIdentifier:#"charityCell"];
cell.charityImage.image = [UIImage imageNamed:#"cleanup"];
cell.charityName.text = #"Garbage cleanup - Crowchild";
cell.charityTagLine.text = #"City of Calgary";
cell.charityDescriptionShort.text = #"We are rounding up anyone that wants to help clean up the grass and nearby areas close to crowchild.";
return cell;
}
default:{
UITableViewCell *cell;
return cell;
}
}
}
#end
Thanks for you help!

I am silly.... I was trying to do this without initializing the data like a com mentor said. The code is correct and if anyone has any similar issues make sure your array of data actually has data in it...
