rangeOfString method call causing unrecognized selector error - ios

Question

I am accessing the address book contacts, and then running a for loop on all of the contacts. The loop's main purpose is to access the First Name and Phone Number values of the user's address book contacts and place those values into NSString objects.
All of the above works perfectly. My problem is that I need to execute specific code if the phone number data contains this string: _$!<Mobile>!$_
So I setup a rangeOfString method call on the object that contains the phone number data and this is causing problems.
Here is what prints to the console once I added the rangeOfString method call to my code:
2014-01-18 12:10:49.190 PhotoTest1[1244:60b] -[__NSCFType rangeOfString:]: unrecognized selector sent to instance 0x14e9ac90
2014-01-18 12:10:49.193 PhotoTest1[1244:60b] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFType rangeOfString:]: unrecognized selector sent to instance 0x14e9ac90'

libc++abi.dylib: terminating with uncaught exception of type NSException
And here is all of my code starting with the for loop. The error prints to the console as soon as it gets to "if([phoneNumber rangeOfString:#"+"].location == NSNotFound)":
for (i = 0; i < [allContacts count]; i++)
{
Person *person = [[Person alloc] init];
ABRecordRef contactPerson = (__bridge ABRecordRef)allContacts[i];
NSString *firstName = (__bridge_transfer NSString
*)ABRecordCopyValue(contactPerson, kABPersonFirstNameProperty);
NSString *phoneNumber = (__bridge_transfer NSString *)ABRecordCopyValue(contactPerson, kABPersonPhoneProperty);
person.firstName = firstName;
person.phoneNumber = phoneNumber;
NSLog(#"%#", phoneNumber);
//MOBILE PHONE PSEUDOCODE STARTS HERE
// If the value of phoneNumber contains the text “_$!<Mobile>!$_” , then we want to grab a substring out of it.
if([phoneNumber rangeOfString:#"_$!<Mobile>!$_"].location == NSNotFound) {
NSLog(#"Not a mobile phone number");
} else {
NSLog(#"It is a mobile phone number");
// If the value of phoneNumber contains a “+”, then grab the substring that starts with the + and then the next additional 10 spaces and place the substring in the mobilePhoneNumber object. (Which will grab the + sign and the 10 digit phone number. )
if([phoneNumber rangeOfString:#"+"].location == NSNotFound) {
NSLog(#"Phone number does not start with a +");
} else {
NSLog(#"Phone number does start with a +");
NSString *subString = [phoneNumber substringWithRange: NSMakeRange(0, [phoneNumber rangeOfString: #"+"].location)];
NSLog(#"%#", subString);
}
}
//PFQUERY CODE TESTING!!!
}
}
}
Thanks for the help.

The phone Number is no string . it is defined as a multival as there can be 0..x numbers there.
you can't just treat it as a string . you need to enumerate through the multival\
e.g. to get the first of ANY kind
ABMultiValueRef phoneEntries = ABRecordCopyValue(person, kABPersonPhoneProperty);
NSMutableArray *numbers = [NSMutableArray array)];
for(int i = 0; i < ABMultiValueGetCount(phoneEntries); i++) {
NSString *number = (__bridge_transfer NSString*)ABMultiValueCopyValueAtIndex(phoneEntries, i))];
// Do what you want with the number
[numbers addObject:number];
}
CFRelease(phoneEntries);
