Answer 1

I think you are asking how to use the libPhoneNumber-iOS? You should just read their README page which has a rich set of examples.

One basic sample is as follow:

NBPhoneNumberUtil *phoneUtil = [[NBPhoneNumberUtil alloc] init];
NSError *anError = nil;
NBPhoneNumber *myNumber = [phoneUtil parse:@"6766077303"
                          defaultRegion:@"AT" error:&anError];
if (anError == nil) {
    [phoneUtil format:myNumber 
         numberFormat:NBEPhoneNumberFormatINTERNATIONAL
                error:&anError];
}
