Question

hi im developing an ios aplication and the ui was desigbed using the storyboard (first time using it) so i have the folowing:

• entry point: navigation Controller
• rootView view controller (push to many other view some of one are UITableView)
• and then i programatically push (in some controllers) a view loaded from a nib (no problem on this)

each controller has a defined title.

what i want to do is put a rigth button on the nav bar of all view controller so i can push (programatically) to another controller (wish is in a nib, but i coul move it to the SB whit no problem)

i have tried:

• using a custom class and an nib file but i get the same uncustumised nav bar
• overwriting initWithCoder so i can redirect it to de nib file but get an infinite loop (StakOverflow, yay!)

• using a second class to avoid the infinite loop but get an exception:

  Terminating app due to uncaught exception ‘NSGenericException’, reason: ‘This coder requires that replaced objects be returned from initWithCoder:

• add the button manually in the init method of the navbar class, no efect

• replace the navigation bar in the navigation controller initWithCoder, no efect
• same but in the viewDidLoad method of the navigation controller, no efect
• same but in the rootView Controller, no efect

the code i was using was this (and a few variations):

UIBarButtonItem *BTN = [[UIBarButtonItem alloc] 
      initWithImage:[[UIImage alloc] initWithContentsOfFile:@"img.png"] 
      style:UIBarButtonItemStyleBordered 
      target:self 
      action:@selector(pushView)];

[[self navigationItem] setRightBarButtonItem:BTN];

is ther any way that i can archive this, or should i do it manually view per view?

–thanks

Yes, you would need to do in each view controller for it’s navigationItem property. But you can make it easier by creating a category on UIBarButtonItem class which will have a method configuring and returning the button you need everywhere.
So you only need to invoke that category’s method and no need to write same code everywhere.
