Contact Fetching not showing First Time in ios - ios

Question

I am developing a chat app which needs contacts for chatting but when first time it is not showing the contacts again restart the app fetch then it is showing here is my code
-(NSMutableArray *)getAllContacts {
sleep(6);
// The user has previously given access, add the contact
ABRecordRef source = ABAddressBookCopyDefaultSource(addressBookRef);
CFArrayRef allPeople = (ABAddressBookCopyArrayOfAllPeopleInSourceWithSortOrdering(addressBookRef, source, kABPersonSortByFirstName));
CFIndex nPeople = ABAddressBookGetPersonCount(addressBookRef);
NSMutableArray* items = [[NSMutableArray alloc] init];
if (!allPeople || !nPeople) {
NSLog(#"people nil");
}
CFStringRef description = CFCopyDescription(allPeople);
NSLog(#"Array %#", description);
CFRelease(description);
for (int i = 0; i < nPeople; i++) {
// #autoreleasepool {
//data model
ContactsData *contacts = [ContactsData new];
ABRecordRef person = CFArrayGetValueAtIndex(allPeople, i);
//get First Name
CFStringRef firstName = (CFStringRef)ABRecordCopyValue(person,kABPersonFirstNameProperty);
contacts.firstNames = (__bridge NSString*)firstName;
if (firstName != NULL) {
CFRelease(firstName);
}
//get Last Name
CFStringRef lastName = (CFStringRef)ABRecordCopyValue(person,kABPersonLastNameProperty);
contacts.lastNames = (__bridge NSString*)lastName;
if (lastName != NULL) {
CFRelease(lastName);
}
if (!contacts.firstNames) {
contacts.firstNames = #"";
}
if (!contacts.lastNames) {
contacts.lastNames = #"";
}
contacts.contactId = ABRecordGetRecordID(person);
//append first name and last name
contacts.fullname = [NSString stringWithFormat:#"%# %#", contacts.firstNames, contacts.lastNames];
// get contacts picture, if pic doesn't exists, show standart one
CFDataRef imgData = ABPersonCopyImageData(person);
NSData *imageData = (__bridge NSData *)imgData;
contacts.image = [UIImage imageWithData:imageData];
if (imgData != NULL) {
CFRelease(imgData);
}
if (!contacts.image) {
contacts.image = [UIImage imageNamed:#"avatar.png"];
}
//get Phone Numbers
NSMutableArray *phoneNumbers = [[NSMutableArray alloc] init];
ABMultiValueRef multiPhones = ABRecordCopyValue(person, kABPersonPhoneProperty);
for(CFIndex i=0; i<ABMultiValueGetCount(multiPhones); i++) {
#autoreleasepool {
CFStringRef phoneNumberRef = ABMultiValueCopyValueAtIndex(multiPhones, i);
NSString *phoneNumber = CFBridgingRelease(phoneNumberRef);
phoneNumber = [[phoneNumber componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceCharacterSet]] componentsJoinedByString:#""];
if (phoneNumber != nil)[phoneNumbers addObject:phoneNumber];
//NSLog(#"All numbers %#", phoneNumbers);
}
}
if (multiPhones != NULL) {
CFRelease(multiPhones);
}
[contacts setNumbers:phoneNumbers];
//get Contact email
NSMutableArray *contactEmails = [NSMutableArray new];
ABMultiValueRef multiEmails = ABRecordCopyValue(person, kABPersonEmailProperty);
for (CFIndex i=0; i<ABMultiValueGetCount(multiEmails); i++) {
#autoreleasepool {
CFStringRef contactEmailRef = ABMultiValueCopyValueAtIndex(multiEmails, i);
NSString *contactEmail = CFBridgingRelease(contactEmailRef);
if (contactEmail != nil)[contactEmails addObject:contactEmail];
// NSLog(#"All emails are:%#", contactEmails);
}
}
if (multiPhones != NULL) {
CFRelease(multiEmails);
}
[contacts setEmails:contactEmails];
[items addObject:contacts];
#ifdef DEBUG
NSLog(#"Person is: %#", contacts.firstNames);
NSLog(#"Phones are: %#", contacts.numbers);
NSLog(#"Email is:%#", contacts.emails);
#endif
}
// } //autoreleasepool
CFRelease(allPeople);
CFRelease(addressBookRef);
CFRelease(source);
return items;
}
now i am getting the contacts and now i am fetching the contacts from
- (NSFetchedResultsController *)fetchedResultsController
{
if (fetchedResultsController == nil)
{
NSManagedObjectContext *moc = [[self appDelegate] managedObjectContext_roster];
NSEntityDescription *entity = [NSEntityDescription entityForName:#"XMPPUserCoreDataStorageObject"
inManagedObjectContext:moc];
NSSortDescriptor *sd1 = [[NSSortDescriptor alloc] initWithKey:#"sectionNum" ascending:YES];
NSSortDescriptor *sd2 = [[NSSortDescriptor alloc] initWithKey:#"displayName" ascending:YES];
NSArray *sortDescriptors = #[sd1, sd2];
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
[fetchRequest setEntity:entity];
[fetchRequest setSortDescriptors:sortDescriptors];
[fetchRequest setFetchBatchSize:20];
fetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest
managedObjectContext:moc
sectionNameKeyPath:#"sectionNum"
cacheName:nil];
[fetchedResultsController setDelegate:self];
NSError *error = nil;
if (![fetchedResultsController performFetch:&error])
{
DDLogError(#"Error performing fetch: %#", error);
NSLog(#"Error performing fetch");
}
}
return fetchedResultsController;
}
now assigning this fetched controller to array like
self.UserArray=[[[self fetchedResultsController] fetchedObjects] mutableCopy];
but unable to fetch the contacts to tableview where i miss please help me out
