Changing NavigationItem’s font

Question

I have used this code to change a NavigationItem’s title:

self.navigationItem.title = @"My Name is ABC";

How can I change the font size and font as well?

Answer 1

Sample Code :

CGRect frame = CGRectMake(0, 0, 400, 44);
UILabel *label = [[[UILabel alloc] initWithFrame:frame] autorelease];
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont boldSystemFontOfSize:8.0];
label.textAlignment = UITextAlignmentCenter;
label.textColor = [UIColor whiteColor];
label.text = @"Sample custom Title With small Fonts ";
self.navigationItem.titleView = label;

Answer 2

As of iOS5+, you can use the UIAppearance protocol to change the font of the nav title, here's code:

NSMutableDictionary *titleBarAttributes = [NSMutableDictionary dictionaryWithDictionary: [[UINavigationBar appearance] titleTextAttributes]];
[titleBarAttributes setValue:[UIFont fontWithName:@"Helvetica-Bold" size:18] forKey:UITextAttributeFont];
[[UINavigationBar appearance] setTitleTextAttributes:titleBarAttributes];

Answer 3

Since iOS5 you can use the new titleTextAttributes property like so:

NSMutableDictionary *newAttributes = [[NSMutableDictionary alloc] init]; 
[newAttributes setObject:[UIFont boldSystemFontOfSize:18] forKey:UITextAttributeFont];
[self.navigationController.navigationBar setTitleTextAttributes:newAttributes];

Possible keys are:

UITextAttributeFont
UITextAttributeTextColor
UITextAttributeTextShadowColor
UITextAttributeTextShadowOffset
