Not getting "-" "." " " while picking up a contact from phonebook from ABPerson - iphone

Question

I want to get number as it is with "-" " " "." while picking up a contact from phone book here's my code .
My main motive is to extract the country code from the number if + is present.
Also please suggest me if there is any other way to access country code.
- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier;
{
if (property == kABPersonPhoneProperty) {
ABMultiValueRef multiPhones = ABRecordCopyValue(person, kABPersonPhoneProperty);
for(CFIndex i = 0; i < ABMultiValueGetCount(multiPhones); i++) {
if(identifier == ABMultiValueGetIdentifierAtIndex (multiPhones, i)) {
CFStringRef phoneNumberRef = ABMultiValueCopyValueAtIndex(multiPhones, i);
CFRelease(multiPhones);
NSString *phoneNumber = (__bridge NSString *) phoneNumberRef;
CFRelease(phoneNumberRef);
if ([phoneNumber rangeOfString:#"+"].location == NSNotFound) {
phoneNumber = [phoneNumber stringByReplacingOccurrencesOfString:#"(" withString:#""];
phoneNumber = [phoneNumber stringByReplacingOccurrencesOfString:#")" withString:#""];
phoneNumber = [phoneNumber stringByReplacingOccurrencesOfString:#" " withString:#""];
phoneNumber = [phoneNumber stringByReplacingOccurrencesOfString:#"-" withString:#""];
phoneNumber = [phoneNumber stringByReplacingOccurrencesOfString:#"." withString:#""];
self.lblMobileNumber.text = [NSString stringWithFormat:#"%#", phoneNumber];
} else {
NSArray *PhoneNumberComponents = [phoneNumber componentsSeparatedByString:#" "];
NSString * strCountryCode = PhoneNumberComponents[0] ;
[self.btnCountryCode setTitle:strCountryCode forState:UIControlStateNormal];
phoneNumber= [phoneNumber stringByReplacingOccurrencesOfString:PhoneNumberComponents[0] withString:#""];
NSLog(#"countryCodeSepratedStr%#",phoneNumber);
phoneNumber = [phoneNumber stringByReplacingOccurrencesOfString:#"(" withString:#""];
phoneNumber = [phoneNumber stringByReplacingOccurrencesOfString:#")" withString:#""];
phoneNumber = [phoneNumber stringByReplacingOccurrencesOfString:#" " withString:#""];
phoneNumber = [phoneNumber stringByReplacingOccurrencesOfString:#"-" withString:#""];
phoneNumber = [phoneNumber stringByReplacingOccurrencesOfString:#"." withString:#""];
self.lblMobileNumber.text = [NSString stringWithFormat:#"%#", phoneNumber];
}
}
}
}
return NO;
}

I wouldn't be inclined do any of that string manipulation stuff, but just use regular expression to look for + followed by number at start of the string, using capturing parentheses to grab just the country code:
NSError *error;
NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:#"^\\s*\\+\\s*(\\d+)[^\\d]*(.*)$" options:0 error:&error];
NSTextCheckingResult *result = [regex firstMatchInString:phoneNumber options:0 range:NSMakeRange(0, [phoneNumber length])];
if (result) {
NSString *countryCode = [phoneNumber substringWithRange:[result rangeAtIndex:1]];
NSString *phoneNumberWithoutCountryCode = [phoneNumber substringWithRange:[result rangeAtIndex:2]];
} else {
// no country code found
}
