Question

I have setup tab bar controller using interface builder, and each tab bar item is linked to a view controller (4 tabs, 4 view controllers). I want to know if Interface Builder uses an -init method to initialize the view controller because apparently this method does not get called:

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil; 

… and I want to do some initializations. I can’t add that to -viewDidLoad since it is recalled in case of memory warning. Any idea?

Objects loaded from a *.(nib|xib) are inited with:

- (id)initWithCoder:(NSCoder *)inCoder; 

So you could override that or if doing your setup after -initWithCoder: is called is not a problem you could use:

- (void)awakeFromNib; 

from the NSNibAwaking protocol.
