Passing NSMutableArray to the server - ios

Question

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\"

Answer 1

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];

Answer 2

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.

Answer 3

Do this:
for (NSString* aString in _userEmails) {
NSLog(#"The string is %#", aString);
}
You will see that there are no quotes.
