Problems Populating TableView with NSMutableArray - objective-c

Question

I'm using SudzC for an iPhone app. I'm succesfully calling my ASP.Net webservice and pulling the needed data into an NSMutable array called tableData. I have a tableView that should display the contents of tableData; however this is not working. I've looked for hours at this problem. I'm very new to the Objective C world so I'm thinking it's a small oversight on my part. I've linked my TableView to the ViewController (delegate/datasource) as well.
Here's is the code I have:
#import "ViewController.h"
#import "DocumentServiceJSONService.h"
#interface ViewController ()
#end
#implementation ViewController
NSMutableArray *tableData;
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
-(void)viewWillAppear:(BOOL) animated {
tableData = [[NSMutableArray alloc] init];
DocumentServiceJSONService* service = [[DocumentServiceJSONService alloc] init];
[service GetAllEMSDocumentsXMLAsString: self action:#selector(handleGetAllEMSDocuments:)];
[super viewWillAppear:animated];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
-(void) handleGetAllEMSDocuments:(id) result {
if ([result isKindOfClass:[NSError class]]) {
//if an error has occurred, handle it
return;
}
if([result isKindOfClass: [SoapFault class]]) {
return;
}
NSString* xmlString = result;
CXMLDocument *xmlDoc = [[CXMLDocument alloc] initWithXMLString:xmlString options:0 error:nil];
NSArray *nodes = NULL;
nodes = [xmlDoc nodesForXPath:#"//EMSDocuments" error:nil];
for (CXMLElement *node in nodes) {
NSMutableDictionary *item = [[NSMutableDictionary alloc] init];
int counter;
for (counter = 0; counter < [node childCount]; counter++) {
[item setObject:[[node childAtIndex:counter] stringValue] forKey:[[node childAtIndex:counter] name]];
}
//[item setObject:[[node attributeForName:#"DisplayName"] stringValue] forKey:#"DisplayName"];
NSString *displayName = [item objectForKey:#"DisplayName"];
[tableData addObject:displayName];
}
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [tableData count];
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
cell.textLabel.text = [tableData objectAtIndex:indexPath.row];
return cell;
}
#end
Any advice is appreciated.

Make sure you have in your .h the delegate and datasource correctly set:
#interface YourViewController : UIViewController <UITableViewDataSource, UITableViewDelegate>
And if you are using XIBs for the user interface, that the tableview is connected to the File's Owner as datasource and delegate.
