One of the my project i have to display contacts from contact book and compare them from my database.
For that first you have to read data from the addressbook for that apply the code as below.
For that first you have to read data from the addressbook for that apply the code as below.
-(NSMutableArray*)getaddressBookArray{
addressBook = nil;
__block NSMutableArray *arrayOfPeople = nil;
__block BOOL userDidGrantAddressBookAccess;
CFErrorRef addressBookError = NULL;
if ( ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined ||
ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized )
{
addressBook = ABAddressBookCreateWithOptions(NULL, &addressBookError);
dispatch_semaphore_t sema = dispatch_semaphore_create(0);
ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error){
userDidGrantAddressBookAccess = granted;
arrayOfPeople = [(__bridge_transfer NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBook) mutableCopy];
dispatch_semaphore_signal(sema);
});
dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
}
else
{
if ( ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusDenied ||
ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusRestricted )
{
// Display an error.
}
}
return arrayOfPeople;
}
Here three case may happen
1> First you have to check whether user has allowed access of contacts or not then array will be empty
2> Either there are not any records in address book or not then if no contacts available then contacts array remain empty
3> If contacts found then check them from database which you stored internally like this way
In Database I have one table like contacts which has fields like firstName, lastName, number stored which came from sync api i get them in [self getActiveUsers] Method which get data from database.
Then i make one class for make the contact object .
TKContact.h
