Yes you can. It is fairly simple to do. Create a multiline button and use that. The "trick" is to set the titleLabel numberOfLines property so that it likes multilines.

UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom];
button.titleLabel.numberOfLines = 0;
[button setTitle:NSLocalizedString(@"Now\nPlaying", nil) forState:UIControlStateNormal];
[button sizeToFit];

self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];

When you specify a button type of custom it expects you to configure everything... selected state, etc. which is not shown here to keep the answer focused to the problem at hand.

You can host a UIButton as customView inside your bar button (either set the bar button item customView or you can drag one directly on top of your UIBarButtonItem), hook it up as an outlet, then do;

-(void) viewDidLoad
{

  self.customButton.titleLabel.numberOfLines = 2;
  self.customButton.suggestionsButton.titleLabel.lineBreakMode = UILineBreakModeWordWrap;
  self.customButton.suggestionsButton.titleLabel.textAlignment = UITextAlignmentCenter;
}

I create 2 PNG images by myself, and it looks good.

- (void)createCustomRightBarButton_
{
    UILabel * addCustomLabel = [[[UILabel alloc] initWithFrame:CGRectMake(0, 0, 64, 25)] autorelease];
    addCustomLabel.text =@"Now\nPlaying";
    addCustomLabel.textColor = [UIColor whiteColor];
    addCustomLabel.font = [UIFont boldSystemFontOfSize:11];
    addCustomLabel.numberOfLines = 2;
    addCustomLabel.backgroundColor = [UIColor clearColor];
    addCustomLabel.textAlignment = UITextAlignmentCenter;

    CGSize size = addCustomLabel.bounds.size;

    UIGraphicsBeginImageContext(size);      
    CGContextRef context = UIGraphicsGetCurrentContext();       
    [addCustomLabel.layer renderInContext: context];
    CGImageRef imageRef = CGBitmapContextCreateImage(context);
    UIImage * img = [UIImage imageWithCGImage: imageRef];
    CGImageRelease(imageRef);
    CGContextRelease(context);

    self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithImage:img
                                                                           style:UIBarButtonItemStyleBordered 
                                                                          target:self 
                                                                          action:@selector(flipView)]
                                              autorelease];
}
