Log all installed fonts on iOS

for (NSString* family in [UIFont familyNames])
{
    NSLog(@"%@", family);

    for (NSString* name in [UIFont fontNamesForFamilyName: family])
    {
        NSLog(@"  %@", name);
    }
}

Voila- It will list each family name and any available names for use in the system by UI Font.
