Change UINavigationBar font properties?

Question

I have an UINavigationBar added to my UIViewController view. I want to change the fonts properties. Note that I want to change a UINavigationBar not controller. In my app where I use UINavigationController I use self.navigationItem.titleView = label; to display the custom label.

How can I accomplish to have a custom title in my UINavigationBar?

P.S I use this to set the title text self.navBar.topItem.title = @"Information"; of my UINavigationBar.

Answer 1

From iOS 5 onwards we have to set title text color and font of navigation bar using titleTextAttribute Dictionary(predefined dictionary in UInavigation controller class reference).

[[UINavigationBar appearance] setTitleTextAttributes:      [NSDictionary dictionaryWithObjectsAndKeys:          [UIColor blackColor], NSForegroundColorAttributeName,             [UIFont fontWithName:@"ArialMT" size:16.0], NSFontAttributeName,nil]];

Answer 2

(This is not possible using the new iOS 5.0 Appearance API).

Edit:

iOS >= 5.0 :

Set the Title Text Attributes for the Navigationbar:

// Customize the title text for *all* UINavigationBars NSDictionary *settings = @{     UITextAttributeFont                 :  [UIFont fontWithName:@"YOURFONTNAME" size:20.0],     UITextAttributeTextColor            :  [UIColor whiteColor],     UITextAttributeTextShadowColor      :  [UIColor clearColor],     UITextAttributeTextShadowOffset     :  [NSValue valueWithUIOffset:UIOffsetZero]};  [[UINavigationBar appearance] setTitleTextAttributes:settings]; 

iOS < 5.0

UINavigationItem doesn't have a property called label or something, only a titleView. You are only able to set the font by setting a custom label as this title view You could use the following code: (as suggested here)

UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 200, 44)]; label.font = [UIFont fontWithName:@"YOURFONTNAME" size:20.0]; label.shadowColor = [UIColor clearColor]; label.textColor =[UIColor whiteColor]; label.text = self.title;   self.navigationItem.titleView = label;       [label release];
