AbaddressBookRef leaked in iOS

ABAddressBookRef addressBook = ABAddressBookCreate();

I am parsing the address book in iOS, but Leaks instrument reports There are a lot of memory leaks and I can't seem to track down the problem

First, I created the address book.

ABAddressBookRef addressBook = ABAddressBookCreate();< br />CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);

I suspect this is a leak, but ABAddressBookRef and CFArrayRef are automatically released, right?

The rest of my code is below..

CFIndex nPeople = ABAddressBookGetPersonCount(addressBook);
NSMutableArray *List = [[NSMutableArray alloc] init];



 for (int i = 0; i 
 ABRecordRef ref = CFArrayGetValueAtIndex(allPeople, i) ;
 NSNumber *recordId = [NSNumber numberWithInteger:ABRecordGetRecordID(ref)];

 CFStringRef firstName = ABRecordCopyValue(ref, kABPersonFirstNameProperty);
 CFStringRef lastName = ABRecordCopyValue(ref, kABPersonLastNameProperty) ;

 CFDataRef imgData = ABPersonCopyImageData(ref);

 ABMutableMultiValueRef multi = ABMultiValueCreateMutable(kABMultiStringPropertyType);

 multi = ABRecordCopyValue(ref,kABPersonEmailProperty); 


 for (CFIndex i = 0; i 
 CFStringRef email, emailLabel;
 emailLabel = ABMultiV alueCopyLabelAtIndex(multi, i);
 email = ABMultiValueCopyValueAtIndex(multi, i);
 NSString *emails = [NSString stringWithFormat: @"%@", (NSString *)email];
< br /> if (emails)
 {
 NSMutableDictionary *addDict = [[NSMutableDictionary alloc] init];
 [addDict addObject:emails forKey:@"email"];
 [ List addObject:addDict];
 [addDict release];
 }


 CFRelease(email);
 CFRelease(emailLabel);
 
 }

 if (firstName) {
 CFRelease(firstName);
 }

 if (lastName) {
 CFRelease (lastName);
 }

 if (imgData) {
 CFRelease(imgData);
 }

 if (ref) {< br /> CFRelease(r ef);
 }

 CFRelease(multi);
 }


//do something with list
[List release];

Ok, this works and will not leak

ABAddressBookRef addressBook = ABAddressBookCreate();
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);CFIndex nPeople = ABAddressBookGetPersonCount(addressBook);NSMutableArray *List = [[NSMutableArray alloc] init]; for (int x = 0; x
