How to install custom font in mac programmatically in macOS

Question

I am having a mac app in which I have custom font which is not there in my custom font book of application folder in my mac.

So, when an app launches, I checked it that if a font is installed in mac or not with the below code.

NSArray *fonts = [[NSFontManager sharedFontManager] availableFontFamilies];

if ([fonts containsObject:@"Square721 BT"])
{
    NSLog(@"Fonts Available");
}
else
{
    NSLog(@"No fonts");
}

Now, if the font is not already installed, how can I install it programmatically?

1. Add your font ttf file to your application bundle, e.g. in Contents/Resources/Fonts/
2. In your info.plist add the key: ATSApplicationFontsPath and string: Fonts
