Objective-c – Change UINavigationBar font properties

cocoa-touchfontsobjective ctitleuinavigationbar

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.

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]];

Ios – embed a custom font in an iPhone application

iOS 3.2 and later support this. Straight from the What's New in iPhone OS 3.2 doc:

Custom Font Support
Applications that want to use custom fonts can now include those fonts in their application bundle and register those fonts with the system by including the UIAppFonts key in their Info.plist file. The value of this key is an array of strings identifying the font files in the application’s bundle. When the system sees the key, it loads the specified fonts and makes them available to the application.

Once the fonts have been set in the Info.plist, you can use your custom fonts as any other font in IB or programatically.

There is an ongoing thread on Apple Developer Forums:
https://devforums.apple.com/thread/37824 (login required)

And here's an excellent and simple 3 steps tutorial on how to achieve this (broken link removed)

Add your custom font files into your project using Xcode as a resource
Add a key to your Info.plist file called UIAppFonts.
Make this key an array
For each font you have, enter the full name of your font file (including the extension) as items to the UIAppFonts array
Save Info.plist
Now in your application you can simply call [UIFont fontWithName:@"CustomFontName" size:12] to get the custom font to use with your UILabels and UITextViews, etc…

Also: Make sure the fonts are in your Copy Bundle Resources.

Ios – UINavigationBar – Set title programmatically

I've set the title programmatically using code something like this:

navBar.topItem.title = @"title";

where navBar is declared as an IBOutlet UINavigationBar linked to the navigation bar in interface builder. This worked in my app; however, I was not using a tab bar.

If navBar.topItem is the tab bar item, I don't see a way for you to change the title that appears on the navigation bar without also changing the title on the tab bar item, since the navBar's topItem and the tab bar item is the same object.
