iOS Address Book error on ABMultiValueRef - iphone

Question

I'm facing a problem accessing the address book of my iPad 2. In particular I have problems retrieving the email of my contacts. What I want to do is to access the address book, retrieve my contacts and show them in a table view. Everything seems work fine since the name and the surname of the contacts are shown. The problem is with the email property since when I try to retrieve it I get an "EXC_BAD_ACCESS".
The code i wrote to show the tableview record is the following:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *tableIdentifier = #"tableIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:tableIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:tableIdentifier] autorelease];
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.textLabel.backgroundColor = [UIColor clearColor];
cell.detailTextLabel.backgroundColor = [UIColor clearColor];
NSUInteger row = [indexPath row];
NSString *firstName = (NSString *)ABRecordCopyValue([contacts objectAtIndex:row], kABPersonFirstNameProperty);
NSString *lastName = (NSString *)ABRecordCopyValue([contacts objectAtIndex:row], kABPersonLastNameProperty);
NSString *name = [[NSString alloc] initWithFormat:#"%# %#", lastName,firstName];
[firstName release];
[lastName release];
cell.textLabel.text = name;
[name release];
NSArray *emails = [[self getEmailForPerson:row] retain];
/*......*/
return cell;
}
While the function to get the email of my contacts is the following:
- (NSArray *)getEmailForPerson:(NSInteger)index{
//Create the array where emails will be stored
NSMutableArray *m = [[[NSMutableArray alloc] init] autorelease];
//Get the email properties
ABMultiValueRef mails = ABRecordCopyValue([self.contacts objectAtIndex:index], kABPersonEmailProperty);
//Iterate in the multi-value properties
for (int i=0; i<ABMultiValueGetCount(mails); i++) {
//Get the email
NSString *mail = (NSString *) ABMultiValueCopyValueAtIndex(mails, i);
//Add the email to the array previously initializated
[m addObject:mail];
[mail release];
}
CFRelease(mails);
return m;
}
When I run the debugger after this statement
ABMultiValueRef mails = ABRecordCopyValue([self.contacts objectAtIndex:index], kABPersonEmailProperty);
mails seems not initialized since its adress is 0x0 but I cannot understand why.
I hope somebody can help me.
Thanks in advance

Answer 1

ABMultiValueRef mails = ABRecordCopyValue([self.contacts objectAtIndex:index], kABPersonEmailProperty);
It works fine in my app.
Check framework & self.contacts.
My app use two frameworks.
#import <AddressBook/AddressBook.h>
#import <AddressBook/ABAddressBook.h>
