Question

The method setRightBarButtonItems:animated: for a UINavigationItem is not supported in iOS4.

How could I rewrite this code to add 2 buttons on the right in the bar ?

[viewController.navigationItem setRightBarButtonItems:[NSArray arrayWithObjects:helpButton, settingsButton, nil] animated:YES];

thanks

You can set the button’s alpha to 0 before you add it to the view, and then animate it’s value to 1.0.

//..Create the buttons
//Make it invisible
helpButton.alpha = 0.0;
settingsButton.alpha = 0.0

//Add them to the navBar
[self.navigationController.navigationBar addSubview:helpButton];
[self.navigationController.navigationBar addSubview:settingsButton];

//Animate it to 1.0
[UIView animateWithDuration:0.3 animations:^(void) {
      helpButton.alpha = 1.0;
      settingsButton.alpha = 1.0
    }];
