We know that contacts in iOS can be synced from Google, iCloud and Phone. Well, we can fetch a bunch of Contacts using Contacts.framework, but I want to know which account it belongs to.
I mean, I need to differentiate Email and Phone synced contacts. Is there any way to do so?
I am using contact framework. I am getting identifier by using CNContainer, but how to get account name in which contacts are stored and also how fetch that contact’s from that account?
Can you please try fetching All container's and then you can Group those contacts according to the container name
-(void)fetchContacts
{
CNContactStore *store = [[CNContactStore alloc] init];
[store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (granted == YES)
{
NSArray * contactContainerArray = [store containersMatchingPredicate:nil error:nil];
for(CNContainer * container in contactContainerArray) {
NSLog(#"Container name == %# ",container.name);
NSPredicate *predicate = [CNContact predicateForContactsInContainerWithIdentifier:container.identifier];
NSError *error;
NSArray *cnContacts = [store unifiedContactsMatchingPredicate:predicate keysToFetch:keys error:&error];
if (error)
{
NSLog(#"error fetching contacts %#", error);
}
else
{
for (CNContact *contact in cnContacts) {
NSMutableArray *contactNumbersArray = [[NSMutableArray alloc]init];
// contact.givenName;
// contact.familyName;
for (CNLabeledValue *label in contact.phoneNumbers) {
// [label.value stringValue]; Phone Number
}
}
}
}
}
}];
}

It seems on some phones the performance of unifiedContactsMatchingPredicate can be extremely slow while on others it is pretty fast. What may be the cause of the performance discrepancy? As far as I can tell the contacts on different phones aren't stored that differently, is there something else that could be the cause?
How to display contact in table view?
I have fetched the contacts via CNContactStore iOS 9.
- (void) getContacts {
CNContactStore *store = [[CNContactStore alloc] init];
[store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (granted == YES) {
//keys with fetching properties
NSArray *keys = #[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey,CNContactImageDataKey];
NSString *containerId = store.defaultContainerIdentifier;
NSPredicate *predicate = [CNContact predicateForContactsInContainerWithIdentifier:containerId];
NSError *error;
NSArray *cnContactsarray = [store unifiedContactsMatchingPredicate:predicate keysToFetch:keys error:&error];
if (error) {
NSLog(#"error fetching contacts %#", error);
}
else {
for (CNContact *contact in cnContactsarray) {
//store all the contacts as per your requirement
NSLog(#"Name : %#",contact.givenName);
NSLog(#"Id : %#",contact.identifier);//the contact id which you want
[_ContactsCN addObject:contact];
}
}
NSLog(#"array %#",_ContactsCN);
}
}];
}
Any help will be appreciated.
You need to reload data on main thread when your fetch contact from CNContact is complete
to run on main thread
dispatch_async(dispatch_get_main_queue(), ^{// reload your table here
});
I want to delete contact from phone contact from my app, as this ABAddressBookRemoveRecord method is deprecated in i os 9. so now how can i delete contact.
Is there any method in contacts framework??
Thanks Everyone!
The complete AddressBook Framework was deprecated in iOS9, you should check out the Contacts Framework instead:
Contacts Framework
A nice tutorial explaining deleting records here.
The tutorial covers Swift, but the same principle applys to Objective-C as well.
Here is the code if you want to delete all contacts in one go using CNContacts
- (void) deleteAllContacts {
CNContactStore *contactStore = [[CNContactStore alloc] init];
[contactStore requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (granted == YES) {
NSArray *keys = #[CNContactPhoneNumbersKey];
NSString *containerId = contactStore.defaultContainerIdentifier;
NSPredicate *predicate = [CNContact predicateForContactsInContainerWithIdentifier:containerId];
NSError *error;
NSArray *cnContacts = [contactStore unifiedContactsMatchingPredicate:predicate keysToFetch:keys error:&error];
if (error) {
NSLog(#"error fetching contacts %#", error);
} else {
CNSaveRequest *saveRequest = [[CNSaveRequest alloc] init];
for (CNContact *contact in cnContacts) {
[saveRequest deleteContact:[contact mutableCopy]];
}
[contactStore executeSaveRequest:saveRequest error:nil];
DDLogVerbose(#"Deleted contacts %lu", cnContacts.count);
}
}
}];
}
AddressBook api is deprecated in ios 9. I want to load all contacts in an array and display it in a UITableView. I don't want to use iOS default ContactPicker as I have to do some customization while displaying. How to load all contact list in an array for further use?
First I had to check the permission id it is not defined then ask for permission for accessing contacts. Like this:
CNAuthorizationStatus status = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
if (status == CNAuthorizationStatusNotDetermined) {
[self.contactStore requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError *error) {
if (granted) {
[self loadUserListFromPhoneBook];
}
}];
}
else if(status == CNAuthorizationStatusAuthorized) {
[self loadUserListFromPhoneBook];
}
After that I had to iterate through the contact list and load all contacts like this:
-(void) loadUserListFromPhoneBookFor
{
NSMutableArray *contacts = [NSMutableArray array];
NSError *error;
CNContactFetchRequest *request = [[CNContactFetchRequest alloc] initWithKeysToFetch:#[CNContactIdentifierKey, [CNContactFormatter descriptorForRequiredKeysForStyle:CNContactFormatterStyleFullName]]];
BOOL success = [self.contactStore enumerateContactsWithFetchRequest:request error:&error usingBlock:^(CNContact *contact, BOOL *stop) {
[contacts addObject:contact];
}];
if (!success) {
NSLog(#"error = %#", error);
}
CNContactFormatter *formatter = [[CNContactFormatter alloc] init];
for (CNContact *contact in contacts) {
NSString *string = [formatter stringFromContact:contact];
NSLog(#"contact = %#", string);
}
}
You can use necessary keys for getting more information. Have a look at this for more information. Its has all new contact classes. This video of WWDC helped a lot.
