iphone - Navigation Bar Title Font Size

Question

I need to change the size of the Navigation Bar title text for one view controller in my iPhone app. I'm using iOS5, and tried the following code:

if ([self.tabBarItem respondsToSelector:@selector(setTitleTextAttributes:)]) {
    NSLog(@"*** Support method(iOS 5): setTitleTextAttributes:");
    [self.tabBarItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                [UIFont fontWithName:@"AmericanTypewriter" size:20.0f], UITextAttributeFont,
                                                [UIColor blackColor], UITextAttributeTextColor,
                                                [UIColor grayColor], UITextAttributeTextShadowColor,
                                                [NSValue valueWithUIOffset:UIOffsetMake(0.0f, 1.0f)], UITextAttributeTextShadowOffset,
                                                nil]];
}

However this only applies to the tabBarItem.

Answer 1

You got it already,but you can also use following attributes methods.

For Color,

NSDictionary *attributes=[NSDictionary dictionaryWithObjectsAndKeys:[UIColor RedColor],UITextAttributeTextColor, nil];

self.navigationController.navigationBar.titleTextAttributes = attributes;

For Size,

NSDictionary *size = [NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"Arial" size:17.0],UITextAttributeFont, nil];

self.navigationController.navigationBar.titleTextAttributes = size;

Thanks.

For iOS 7 and above

For Size:

NSDictionary *size = [NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"Arial" size:17.0],NSFontAttributeName, nil];

self.navigationController.navigationBar.titleTextAttributes = size;
