TableView Delegate Messages Not Being Called - objective-c

Question

SOLVED: Not really a solution, but I just used a .xib rather than trying to use the storyboard thing. Whatever I was trying to do with the storyboard was somehow messing up the TableView delegate methods from being called. Thanks for all the insight you guys provided.
I have a UIViewController that contains a UITableView that should be populated by an array.
Unfortunately the UITableView does not get populated by the array (which is not empty).
My .h file:
#interface Directory : UIViewController <UITableViewDelegate, UITableViewDataSource, UISearchBarDelegate> {
NSArray *listData;
NSArray *savedListData;
MKMapView* mapUI;
UISearchBar* searchBar;
NSArray * originalListData;
UITableView* placeList;
DirInfoListing *infoInst;
NSString *searchInit;
NSString *openInit;
NSMutableArray *buildings;}
#property (nonatomic, retain) NSArray *listData;
#property (nonatomic, retain) NSArray *savedListData;
#property (nonatomic, retain) IBOutlet UISearchBar* searchBar;
#property (nonatomic, retain) IBOutlet UITableView* placeList;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil list: (NSArray*)array mapView:(MKMapView*) map;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil list:(NSArray*)array mapView:(MKMapView*) map search:(NSString*) ss;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil list: (NSArray*)array mapView:(MKMapView*) map open:(NSString*) openTx;
-(void)doDBLoad;
#end
And relevant stuff from my .m file:
#import "Directory.h"
#interface Directory ()
#end
#implementation Directory
#synthesize listData, savedListData;
#synthesize searchBar;
#synthesize placeList;
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
NSLog(#"ListData count: %lu", (unsigned long)savedListData.count);
//This returns a valid number of 74 items
return [self.savedListData count];
}
/*
* Populates the table with list data and provides title. AND DOES NOT GET CALLED
*/
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *tID = #"tablIDDirect";
UITableViewCell *c = [tableView dequeueReusableCellWithIdentifier:tID];
if(c == nil) {
c = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:tID];
}
NSInteger r = [indexPath row];
if([self.listData objectAtIndex:r] != nil){
c.textLabel.text = ((DBBuilding*)[self.savedListData objectAtIndex:r]).Name;
c.detailTextLabel.text = ((DBBuilding*)[self.savedListData objectAtIndex:r]).Acronym;
}
c.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return c;
}
/*
* Displays an entry according to the table selection and redirects the user to the Directory Information Listing.
*/
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSInteger r = [indexPath row];
[tableView deselectRowAtIndexPath:indexPath animated:YES];
if(infoInst != nil) {
infoInst = nil;
}
infoInst = [[DirInfoListing alloc] initWithNibName:#"DirInfoListing" bundle:nil building:[self.savedListData objectAtIndex:r] map:mapUI];
}
/*
* Notification that the Directory is the active view
*/
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
if(openInit != nil)
{
[self openEntry:openInit];
openInit = nil;
}
placeList = [[UITableView alloc] init];
placeList.dataSource = self;
placeList.delegate = self;
[placeList reloadData];
}
/*
* Notification that the Directory is no longer the active view
*/
- (void)viewDidDisappear:(BOOL)animated
{
[super viewDidDisappear:animated];
}
- (void)viewDidLoad
{
NSLog(#"ListData count: %lu", (unsigned long)listData.count);
//Also returns a valid number of 74 objects within the array
savedListData = [[NSArray alloc] initWithArray:listData];
//That get put into another array just for my sanity
[super viewDidLoad];
// Do any additional setup after loading the view.
searchBar.text = searchInit;
[self performSearch:searchInit];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
The -(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)sectionmethod gets called, but none of the other UITableView delegate methods are called and I am at a loss as to why this happens.
Also, this whole chunk of code is pulled from another one of my apps (That works correctly) using .xibs and DOES NOT use storyboards. This app (the one I'm having problems with) uses storyboards, which I am not very familiar with. I may be doing something wrong with calling and using the storyboard, but I am just not sure. If there may be something related to that I can provide more information.
Could you guys please go over my code and maybe see where I've gone wrong?
Thanks!

In your "viewDidLoad" method, change one line to this:
self.savedListData = [[NSArray alloc] initWithArray:listData];
Except "listData" needs to be something. "self.listData" might be that something, but on my first pass, I do not see where "self.listData" gets populated or set.
With properties, you usually use "self." to access (set and get) everything for the properties everywhere except in the init methods.
The reason the table is not displaying anything is because your "numberOfRowsInSection" method is likely returning zero. Set a breakpoint and check that.
