App crashes on device but not in simulator pushing an UITableView - iphone

Question

This is the first time I write here but I have a problem that cannot handle :(...
The problem comes when I push an UITableView after push a cell in another table, if I create a general UITableViewController and push it, works, but if I redefine the class with all the necessary methods doesn´t work.
I´ve implemented this before in other code and it works, but now, after updating to Xcode 4.5, doesn´t work...
This is the source code of the view I want to push:
#interface ECDetailSettingsTableView ()
#end
#implementation ECDetailSettingsTableView
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Uncomment the following line to preserve selection between presentations.
// self.clearsSelectionOnViewWillAppear = NO;
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return 4;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"ECDetailSettingsCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (cell == nil) cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"ECDetailSettingsCell"];
// Configure the cell...
return cell;
}
And this is the code that push the tableview:
/********************* Pushing View *********************/
[tableView deselectRowAtIndexPath:indexPath animated: YES];
_themeTable = [self.storyboard instantiateViewControllerWithIdentifier:#"ECDetailSettingsViewController"];
[self.navigationController pushViewController:_themeTable animated:YES];
PD: Thanks for all, and sorry if i´ve made gramatical mistakes :).

maybe if you use segue in storyboard this generete an error, because this only work with iOS 6.
