How to add custom fonts to an iPhone app?

Question

What must I do to get an UIFont object with a custom font? I remember there was also something going on in the Info.plist file.

What font file formats are supported?

Answer 1

Programming way (Swift)

Add the fonts to your project at the resource folder
And add this function:

func loadFont(filePath: String) {

    let fontData = NSData(contentsOfFile: filePath)!

    let dataProvider = CGDataProviderCreateWithCFData(fontData)
    let cgFont = CGFontCreateWithDataProvider(dataProvider)!

    var error: Unmanaged?
    if !CTFontManagerRegisterGraphicsFont(cgFont, &error) {
        let errorDescription: CFStringRef = CFErrorCopyDescription(error!.takeUnretainedValue())
        print("Unable to load font: %@", errorDescription)
    }
}

Use example:

if let fontPath = NSBundle.mainBundle().pathForResource("MyCustomFont", ofType: "ttf") {
    loadFont(fontPath)
}

let myFont = UIFont(name: "MyCustomFont", size: CGFloat(18))
