Exception at cellForRowAtIndexPath function - UITableView

I want to display a list of data on "UITableView".

When I run the code I get the following error: 

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 
'unable to dequeue a cell with identifier Cell - must register a nib or a class for the 
identifier or connect a prototype cell in a storyboard'

I get the error given above when I run the code below. The error is thrown at the cellForRowAtIndexPath function. How can I solve this error?

@interface TheViewController ()

@property (strong, nonatomic) NSMutableArray *myTData;
@property (weak, nonatomic) IBOutlet UITableView *tableViewOutlet;

@end

@implementation TheViewController
- (void)viewDidLoad
{
    self.tableViewOutlet.delegate = self;
    self.tableViewOutlet.dataSource = self;
    self.tableViewOutlet.scrollEnabled = YES;
    self.myData = [[NSMutableArray alloc] initWithObjects:@"obj1", @"obj2", nil];
    [self.tableViewOutlet reloadData];
    [super viewDidLoad];
}

#pragma mark UITableViewDataSource methods

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger) section {
    return myData.count;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
    if (cell == nil) {
        cell = [[UITableViewCell alloc]
                initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"hede"];
    }
    [cell.textLabel setText: [myData objectAtIndex:indexPath.row]];
    [cell.detailTextLabel setText:@"hede hodo"];
    //
// Configure the cell..
    return cell;
}

#pragma mark UITableViewDelegate methods

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *selectedCell = [tableView cellForRowAtIndexPath:indexPath];
}

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
#warning Potentially incomplete method implementation.
    // Return the number of sections.
    return 1;
}

@end

The exception is exactly what it says it is.

In iOS 5, you would call [tableView dequeueReusableCellWithIdentifier:CellIdentifier] and if it didn't return one, you would create one. The new call -dequeueReusableCellWithIdentifier:forIndexPath: should have a NIB or cell class registered and it will then always succeed.

You should call either 

- (void)registerNib:(UINib *)nib forCellReuseIdentifier:(NSString *)identifier

or 

- (void)registerClass:(Class)cellClass forCellReuseIdentifier:(NSString *)identifier

in your -viewDidLoad method.

In your storyboard, select the prototype cell, go to inspector and give the cell the identifier "Cell" or whatever you want as long as you have the same here : static NSString *CellIdentifier = @"Cell";
