Question

When creating a new view controller to be pushed onto the stack, what is the correct method to use to populate that view controller with data?

I have a data object that I need to send to the view controller, which will then set it’s text fields, etc. with the data.

ItemDetailViewController_iPad *detailViewController = [[ItemDetailViewController_iPad alloc] initWithNibName:@"ItemDetailViewController_iPad" bundle:nil];
[detailViewController populateWithData:_data];


[self.navigationController pushViewController:detailViewController animated:YES];

in ItemDetailViewController_iPad:

-(void) populateWithData:(Item*)_data
{
    self.data = _data;
    self.navigationItem.title = self.data.title;
    self.descriptionText.text = self.data.desc; //the text does not get updated - it's the default text from the nib file
    NSLog(@"Desc: %@", self.data.desc); //this logs valid data

}

You can also declare a property in that VC and then set that property before pushing it. Then in the viewDidLoad method for the pushed VC, set the view’s title and text field.
