Howto Enable Font Antialiasing in Windows

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:

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

1. Add your custom font files into your project using Xcode as a resource
2. Add a key to your Info.plist file called UIAppFonts.
3. Make this key an array
4. For each font you have, enter the full name of your font file (including the extension) as items to the UIAppFonts array
5. Save Info.plist
6. 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.

Do you mean setting the AntiAliasType ?

textField.antiAliasType = AntiAliasType.NORMAL;
