I'm here a bit late, but I took PetahChristian's solution and created a Swift version in the form of an extension. This is working for me. I've found that when you try to get a font using a font name and a size using the regular way that it always looks in the main bundle for the font file, and there's no method that takes a bundle identifier as a parameter. It would be nice if Apple would make one.
Swift:
public extension UIFont {
public static func jbs_registerFont(withFilenameString filenameString: String, bundle: Bundle) {
guard let pathForResourceString = bundle.path(forResource: filenameString, ofType: nil) else {
print("UIFont+: Failed to register font - path for resource not found.")
return
}
guard let fontData = NSData(contentsOfFile: pathForResourceString) else {
print("UIFont+: Failed to register font - font data could not be loaded.")
return
}
guard let dataProvider = CGDataProvider(data: fontData) else {
print("UIFont+: Failed to register font - data provider could not be loaded.")
return
}
guard let font = CGFont(dataProvider) else {
print("UIFont+: Failed to register font - font could not be loaded.")
return
}
var errorRef: Unmanaged<CFError>? = nil
if (CTFontManagerRegisterGraphicsFont(font, &errorRef) == false) {
print("UIFont+: Failed to register font - register graphics font failed - this font may have already been registered in the main bundle.")
}
}
}
Usage Example:
UIFont.jbs_registerFont(
withFilenameString: "Boogaloo-Regular.ttf",
bundle: Bundle(identifier: "com.JBS.JBSFramework")!
)
