Is there any faster way to find a single number using ABAdressBook? - ios

Question

How to find a single number from ABAdressBook which contains 10 000 contacts?
Currently I am using ABAddressBookRef. Is there an alternative method to reduce iterating?
My code snippet:
if([numberType intValue] == NUMBER_TYPE_EXTERNAL && [appDelegate isNativeContactAccess] == YES)
{
NSPredicate *predicate = [NSPredicate predicateWithFormat:#"(numberType == %#)",[NSNumber numberWithInt:NUMBER_TYPE_EXTERNAL]];
[fetchRequest setPredicate:predicate];
NSArray *results = [context executeFetchRequest:fetchRequest error:&error];
/* The method ABAddressBookCreate() is deprecated in ios 6 so below method is used here */
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
for (NSInteger resultCnt=0; resultCnt<[results count]; resultCnt++)
{
Contact *contact = [results objectAtIndex:resultCnt];
ABRecordID r = [contact.indexValue intValue];
ABRecordRef fetchData = ABAddressBookGetPersonWithRecordID(addressBook, r);
if(fetchData != nil)
{
NSUInteger lengthOfSearchStr = [searchNumber length];
ABMultiValueRef multi = ABRecordCopyValue(fetchData, kABPersonPhoneProperty);
NSUInteger j=0;
for(j=0; j<ABMultiValueGetCount(multi); j++)
{
NSString *getNum = (NSString *)ABMultiValueCopyValueAtIndex(multi, j);
NSString *removedspecialchar6 = [getNum stringByReplacingOccurrencesOfString:#"[^0-9*+#]" withString:#"" options:NSRegularExpressionSearch range:NSMakeRange(0,[getNum length])];
if(lengthOfSearchStr <= [removedspecialchar6 length])
{
number = [removedspecialchar6 substringFromIndex:[removedspecialchar6 length] - lengthOfSearchStr];
if([number isEqualToString:searchNumber])
{
[getNum release];
CFRelease(addressBook);
CFRelease(multi);
return contact;
}
}
[getNum release];
}
CFRelease(multi);
}
}
CFRelease(addressBook);
}

NSUInteger index;
NSUInteger findIndex;
ABAddressBookRef addressBook = ABAddressBookCreate();
NSArray *constactsNo = (NSArray *) ABAddressBookCopyArrayOfAllPeople(addressBook);
if ( constactsNo ==nil )
{
CFRelease(addressBook);
return;
}
for ( index=0; index<[constactsNo count]; index++ )
{
ABRecordRef find = (ABRecordRef)[constactsNo objectAtIndex:index];
ABMutableMultiValueRef phoneNumbers = ABRecordCopyValue(find, kABPersonPhoneProperty);
CFIndex phoneNumberCount = ABMultiValueGetCount( phoneNumbers );
for ( findIndex =0; findIndex <phoneNumberCount; findIndex ++ )
{
CFStringRef phoneNumberLabel = ABMultiValueCopyLabelAtIndex( phoneNumbers, findIndex );
CFStringRef phoneNumberValue = ABMultiValueCopyValueAtIndex( phoneNumbers, findIndex );
CFStringRef phoneNumberLocalizedLabel = ABAddressBookCopyLocalizedLabel( phoneNumberLabel );
CFRelease(phoneNumberLocalizedLabel);
CFRelease(phoneNumberLabel);
CFRelease(phoneNumberValue);
}
}
[constactsNo release];
CFRelease(addressBook);
