Can you use UIAppearance to set the titleview of U

问题:

I currently use this code to set the titleView of my navigation item:

- (void)viewDidLoad 
{ ...
   UIImage *navbarTitle = [UIImage imageNamed:@"navbartitleview1"];
   UIImageView *imageView = [[UIImageView alloc]initWithImage:navbarTitle];
   self.navigationItem.titleView =imageView;
}

Is there a way I could put this code using UIAppearance?

[UINavigationItem appearance]

is not valid.

No you wan't be able to do that with UIAppearence, what you can is to have a UIViewController from where all the others UIViewController will inherit. Think way you avoid having to put that code in all your UIViewControllers.
