cellForRowAtIndexPath not called when compiled with xcode 6.1 - ios

Question

In my app I have a popup with a [table view][1] .
When compiled with Xcode 5.1 everything works fine, but the same code compiled with Xcode 6.1 failed to call the [cellForRowAtIndexPath][3] [delegate][4] method.
The other delegate meths are called.
One intersting point is self.tableView.rowHeight; returns -1
I have tried explicitly setting the delegate and data source to self but that makes not difference
The class is called by the following code;
`-(IBAction)selectLanguage:(id)sender
{
ATLMLanguagePopoverTableViewController *pvc = [[ATLMLanguagePopoverTableViewController alloc] initWithNibName:nil bundle:nil];
pvc.target = self;
pvc.action = #selector(popoverDidSelectItem:);
pvc.items = [[[ATLMLibraryManager getManager]libraryDefaults]getAvailableLanguageNames];
_myPopoverController.contentViewController = pvc;
[_myPopoverController setPopoverContentSize:[pvc popoverContentSize]];
[_myPopoverController presentPopoverFromBarButtonItem:(UIBarButtonItem *)sender permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
}
`
Hear is the definition of the class

Answer 1

OK to answer my own question;
Basically the code adds the model to the view controller after the init method is called. However is seem the thread model has changed a bit and the view is created before the model is added so the row count in the model is zero
The solution is to pass the model as part of the init method.
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil items:(NSArray *)itemArray
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
items = [itemArray copy];
selectedItem = -1;
target = nil;
action = nil;
}
return self;
}
