I'm using this in my viewWillAppear: to print all my contacts names and numbers to my console.
- (void)viewWillAppear:(BOOL)animated
{
CFErrorRef error = nil;
// Request authorization to Address Book
ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, &error);
if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined) {
ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error)
{
if (granted) {
// First time access has been granted, add all the user's contacts to array.
contactsObjects = (__bridge NSMutableArray *)(ABAddressBookCopyArrayOfAllPeople(addressBookRef));
} else {
// User denied access.
// Display an alert telling user that they must allow access to proceed to the "invites" page.
}
});
}
else if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) {
// The user has previously given access, add all the user's contacts to array.
contactsObjects = (__bridge NSMutableArray *)(ABAddressBookCopyArrayOfAllPeople(addressBookRef));
}
else {
// The user has previously denied access
// Send an alert telling user that they must allow access to proceed to the "invites" page.
}
NSLog(@"%@", contactsObjects);
}
and here's the output
With this error message:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFType length]: unrecognized selector sent to instance 0x16ec2190'***
What's the problem?

Problem is on cell.textLabel.text = self.contactsObjects[indexPath.row]; underneath the //configure the cells. in the cellForRowAtIndexPath: method.
