I have a CharTableController, View and TableView on my IB. The CharTableController is using "CharTableController" in class identity. And this is how I implemented in the .h, and I want use the "CharTableController" to control the table only:

@interface CharTableController : UITableViewController <UITableViewDelegate, UITableViewDataSource>{
//  IBOutlet UILabel *debugLabel;
    NSArray *listData;
}
//@property (nonatomic, retain) IBOutlet UILabel *debugLabel;
@property (nonatomic, retain) NSArray *listData;
@end

It is the .m:

#import "CharTableController.h"

@implementation CharTableController
@synthesize listData;

- (void)viewDidLoad {
        //NSLog(@"bulll");
        //  [debugLabel setText:@"success"];
    NSArray *array = [[NSArray alloc] initWithObjects:@"A", @"B", @"C", @"D", @"E", nil];
    self.listData = array; 
    [array release]; 
    [super viewDidLoad];
}


- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{ 
    return [self.listData count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier];

    if (cell == nil) { 
        cell = [[[UITableViewCell alloc]
            initWithStyle:UITableViewCellStyleDefault 
            reuseIdentifier:SimpleTableIdentifier] autorelease];

        NSUInteger row = [indexPath row]; cell.textLabel.text = [listData objectAtIndex:row]; 
    }
    return cell;
}

@end

In the IB, I already assign the CharTableController's view to Table View in IB. And Table View is under the View, in IB. After I run the program, I can see the table view, but I can't see any char in the table view, why? What's wrong with my code? thz.
