Question

I have tried using the obvious method as outlined in the following example but my passed variable (rootcategory) is still nil on viewDidLoad in the loaded view.

This is my code:

CategoryViewController *viewController = [[CategoryViewController alloc] initWithNibName:@'CategoryViewController' bundle:[NSBundle mainBundle]]; self.categoryViewController.rootCategory = @'433'; self.categoryViewController = viewController; [viewController release]; 

I am synthesizing a property in the header as follows:

@property (nonatomic, readwrite) NSString *rootCategory; 

Answer 1

You are allocating viewController, and try to change self.categoryViewController before it is assigned to viewController.

CategoryViewController *viewController = [[CategoryViewController alloc] initWithNibName:@'CategoryViewController' bundle:[NSBundle mainBundle]]; viewController.rootCategory = @'433'; self.categoryViewController = viewController; [viewController release]; 

should work.
