Passing NSMutableArray to the server

I'm currently working with AddressBook in iOS, I'm getting the emails from all the contacts of the user, and putting them into the NSMutableArray. Now I must to pass this array to the server[PHP]. But the problem that is the emails are in the double quotes, so it looks something like this:

(
  "user@gmail.com",
  "user2@gmail.com",
  "user3@gmail.com"
)

That is my code:

ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
__block BOOL accessGranted = NO;
if (ABAddressBookRequestAccessWithCompletion != NULL) { // we're on iOS 6
    dispatch_semaphore_t sema = dispatch_semaphore_create(0);
    ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
        accessGranted = granted;
        dispatch_semaphore_signal(sema);
    });
    dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
}
else { // we're on iOS 5 or older
    accessGranted = YES;
}

if (accessGranted) {
    CFArrayRef people = ABAddressBookCopyArrayOfAllPeople(addressBook);
    _usersEmails = [[NSMutableArray alloc] initWithCapacity:CFArrayGetCount(people)];
    for (CFIndex i = 0; i < CFArrayGetCount(people); i++) {
        ABRecordRef person = CFArrayGetValueAtIndex(people, i);
        ABMultiValueRef emails = ABRecordCopyValue(person, kABPersonEmailProperty);
        for (CFIndex j=0; j < ABMultiValueGetCount(emails); j++) {
            NSData* email = [(__bridge NSString*)ABMultiValueCopyValueAtIndex(emails, j) dataUsingEncoding:NSUTF8StringEncoding];
            [_usersEmails addObject:email];
        }
        CFRelease(emails);
    }
    CFRelease(addressBook);
    CFRelease(people);

Web-programmer that was implementing the server-side, told me that I must to pass the array of strings without the double quotes.

How can I remove the double quotes in each string of my array?

Update:

This is the piece of the actual data that had been received by the server:

\"user@gmail.com\"','\"user@gmail.com\"','\"user@gmail.com\"','\"user@me.com\"

You can use the NSString's substringFromIndex and substringToIndex methods to eliminate the first and last characters. Something like [[string substringToIndex:string.length - 1] substringFromIndex:1];

EDIT:

And can't you check/remove the quotation marks here:

NSData* email = [(__bridge NSString*)ABMultiValueCopyValueAtIndex(emails, j) dataUsingEncoding:NSUTF8StringEncoding];

by writing something like: 

NSString *string = (__bridge NSString*)ABMultiValueCopyValueAtIndex(emails, j);
NSString *stringWithoutQuotations = [[string substringToIndex:string.length - 1] substringFromIndex:1];
NSData* email = [stringWithoutQuotations  dataUsingEncoding:NSUTF8StringEncoding];

Do this:

for (NSString* aString in _userEmails) {
    NSLog(@"The string is %@", aString);
}

You will see that there are no quotes.

The quotes are shown when NSString is printed to the console--I don't think your strings actually contain quotation marks..

Try using the debugger inspector instead to double-check.
