    I haven't tried this yet. But my guess, would be to create a UILabel and set it's font and size and assign it as the titleView of the navigation Item;
    UILabel *bigLabel = [[UILabel alloc] init];
bibLabel.text = @"I am BIG";
bigLabel.font = [UIFont fontWithName:@"Arial" size: 22.0];
self.navigationItem.titleView = bigLabel;
[bigLabel release];

    I put this code in my loadView method, but it doesn't shows anything :|

    UILabel *bigLabel = [[UILabel alloc] init];
    bigLabel.text = @I am BIG;
    bigLabel.font = [UIFont fontWithName:@Arial size: 22.0];
    self.navigationItem.customTitleView = bigLabel;
    [bigLabel release];

    Hmmm. I don't have access to my mac right now to test the code.
    Maybe, the font name is not a valid one,
    test it with code below
    UILabel *bigLabel = [[UILabel alloc] init];
bibLabel.text = @"I am BIG";
bigLabel.font = [UIFont systemFontOfSize:22.0];
self.navigationItem.titleView = bigLabel;
[bigLabel release];
    Also, I noticed you are using customTitleView property in setting the navigation item. I don't think that is still available in SDK5, so use the titleView property.

    Make sure, you don't have any warnings. Objective C is dynamically typed, so it's better to
    TREAT WARNINGS AS ERRORS.

    This is my code for showing a label in my navigationBar title:

    UILabel *myTitle = [[UILabel alloc] init];
    myTitle.text = @This is my title;
    self.navigationItem.titleView = myTitle;
    [myTitle release];

    but it doesn't show anything, what's wrong?

    Try setting myTitle.frame to something reasonable.

    If IB was any better, all this could be done with so much ease :(

    The docs for the UINavigationItem titleView property say that if the nav item's left button is non-nil, the custom title view is not displayed:
    This property is ignored if leftBarButtonItem is not nil.

    So if you have a left button (such as the default "back" button), it's probably ignored.

    I`m using this code to customize title view, its work for me, if you have problem I sugest that try to localize title view in stack of items.. in my case it`s working because topItem is the title view...

    Insert in loadview..
    	UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 120, 30)];
	[label setFont:[UIFont boldSystemFontOfSize:16.0]];
	[label setBackgroundColor:[UIColor clearColor]];
	[label setTextColor:[UIColor whiteColor]];
	[label setText:self.title];
	[self.navigationController.navigationBar.topItem setTitleView:label];
	[label release];

    Works exactly as required! Thanks for this ;)

    It was crashing for me, unless I changed the following line: 
    	[self.navigationController.navigationBar.topItem setTitleView:label];
    to: 
    	[self.navigationController.navigationBar.topItem setTitleView:label.text];

    Then it works! Thanks!

    You just missed one thing - to size the view. This can be done either with the initWithFrame intialiser, or by calling sizeToFit like this:
    UILabel *bigLabel = [[UILabel alloc] init];
bigLabel.text = @"I am BIG";
bigLabel.font = [UIFont fontWithName:@"Arial" size: 22.0];
[bigLabel sizeToFit];
self.navigationItem.titleView = bigLabel;
[bigLabel release];

    This is your best option:
    // List of Fonts Available on the iPhone - http://ajnaware.wordpress.com/2008/10/24/list-of-fonts-available-on-the-iphone/
	UILabel *label = [[UILabel alloc] init];
	label.font = [UIFont fontWithName:@"Helvetica-Bold" size: 15.0];
	// Optional - label.text = @"NavLabel";
	[label setBackgroundColor:[UIColor clearColor]];
	[label setTextColor:[UIColor whiteColor]];
	[label setText:self.title];
	[label sizeToFit];
	[self.navigationController.navigationBar.topItem setTitleView:label];
	[label release];

    Here's how I'm doing it:
    - (void)SetNavigationTitle:(NSString*)title AndSubtitle:(NSString*)subtitle
{
  if (subtitle == nil)
  {
    self.navigationItem.titleView = nil;
    self.navigationItem.title = title;
    return;
  }
  
  // set the default title anyway, so the next view controllers will have the correct text on their "back" button
  self.navigationItem.title = title;
  
  #define LEFT_OFFSET 15
  
  // Replace titleView
  CGRect headerTitleSubtitleFrame = CGRectMake(LEFT_OFFSET, 0, 200, 44);    
  UIView* _headerTitleSubtitleView = [[UILabel alloc] initWithFrame:headerTitleSubtitleFrame];
  _headerTitleSubtitleView.backgroundColor = [UIColor clearColor];
  _headerTitleSubtitleView.autoresizesSubviews = YES;
  
  CGRect titleFrame = CGRectMake(LEFT_OFFSET, 2, 160, 24);  
  UILabel *titleView = [[UILabel alloc] initWithFrame:titleFrame];
  titleView.backgroundColor = [UIColor clearColor];
  titleView.font = [UIFont boldSystemFontOfSize:20];
  titleView.textAlignment = UITextAlignmentCenter;
  titleView.textColor = [UIColor whiteColor];
  titleView.shadowColor = [UIColor darkGrayColor];
  titleView.shadowOffset = CGSizeMake(0, -1);
  titleView.text = title;
  titleView.adjustsFontSizeToFitWidth = YES;
  [_headerTitleSubtitleView addSubview:titleView];
  [titleView release];
  
  CGRect subtitleFrame = CGRectMake(LEFT_OFFSET, 24, 160, 44-24);   
  UILabel *subtitleView = [[UILabel alloc] initWithFrame:subtitleFrame];
  subtitleView.backgroundColor = [UIColor clearColor];
  subtitleView.font = [UIFont boldSystemFontOfSize:13];
  subtitleView.textAlignment = UITextAlignmentCenter;
  subtitleView.textColor = [UIColor whiteColor];
  subtitleView.shadowColor = [UIColor darkGrayColor];
  subtitleView.shadowOffset = CGSizeMake(0, -1);
  subtitleView.text = subtitle;
  subtitleView.adjustsFontSizeToFitWidth = YES;
  [_headerTitleSubtitleView addSubview:subtitleView];
  [subtitleView release];
  
  self.navigationItem.titleView = _headerTitleSubtitleView;
  [_headerTitleSubtitleView release];
}

    How do I set the label in the above code to show no background? With the above code the label has a white background.

    Thanks

    Hello,

    How would I change the font size without changing the font?
