In the case where i=0 and last name is nil you allocate a new NSMutableArray but don't put anything in it. You then try and access the first element to build the full name - you should add an empty string as you do for the case where i>0 — Paulw11

See [self.FirstName objectAtIndex:i] & [self.LastName objectAtIndex:i] lines. Have you checked that both contains some values? — Mehul Patel

hear [self.FirstName objectAtIndex:i] the i value is showing "0" @Kampai — Shaik Nayeemuddin

What about self.LastName array? Does it contains any value? — Mehul Patel

-(void)retriveContactsFromAddressBook
{
    //CFErrorRef error = NULL;
    ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);

    self.LastName=[[NSMutableArray alloc]init];
    self.FirstName=[[NSMutableArray alloc]init];
    self.fullName=[NSMutableArray arrayWithObject:full];

    if (addressBook!=nil)
    {
        NSArray *allContacts=(__bridge_transfer NSArray*)ABAddressBookCopyArrayOfAllPeople(addressBook);
        NSUInteger i=0;
        for ( i = 0; i<[allContacts count]; i++)
        {
            ABRecordRef contactPerson = (__bridge ABRecordRef)allContacts[i];
            NSString *firstName = (__bridge_transfer NSString*)ABRecordCopyValue(contactPerson, kABPersonFirstNameProperty);
            NSString *lastName=(__bridge_transfer NSString*)ABRecordCopyValue(contactPerson, kABPersonLastNameProperty);

            if (firstName == nil) {
                [self.FirstName addObject:@""];
            } else {
                [self.FirstName addObject:firstName];
            }

            if (lastName==nil) {
                [self.LastName addObject:@""];
            } else {
                [self.LastName addObject:lastName];
            }

            NSString *full=[NSString stringWithFormat:@"%@ %@",[self.FirstName objectAtIndex:i],[self.LastName objectAtIndex:i]];

            [self.fullName addObject:full];
        }
    }
    else
    {
        NSLog(@"Error Address book empty");
    }
}

Use like this..

self.LastName=[[NSMutableArray alloc]init];

This line is the problem.. If lastname is nil you didn't insert any object

NSString *full=[NSString stringWithFormat:@"%@ %@",[self.FirstName objectAtIndex:i],[self.LastName objectAtIndex:i]];

But in this line [self.LastName objectAtIndex:i] you try to retrieve object from the empty array that is problem...

Nayeemuddin you are accessing an array with no contents in it, so the exception is occurring.

NSString *full=[NSString stringWithFormat:@"%@ %@",[self.FirstName objectAtIndex:i],[self.LastName objectAtIndex:i]];

here you are accessing object of an array which does not exists. Also you forgot to initialise second array ,

 self.LastName=[[NSMutableArray alloc]init];

You need to insert a null entry into the last name array when you allocate it.

for ( i = 0; i<[allContacts count]; i++)
{
            ABRecordRef contactPerson = (__bridge ABRecordRef)allContacts[i];
             NSString *firstName = (__bridge_transfer NSString*)ABRecordCopyValue(contactPerson, kABPersonFirstNameProperty);
            NSString *lastName=(__bridge_transfer NSString*)ABRecordCopyValue(contactPerson, kABPersonLastNameProperty);

            if (i==0) {
                self.FirstName=[NSMutableArray arrayWithObject:firstName];
                if (lastName==nil) {
                    self.LastName=[[NSMutableArray arrayWithObject:@""];  // <--- This
                } else {
                    self.LastName=[NSMutableArray arrayWithObject:lastName];
                }

            } else {
                [self.FirstName addObject:firstName];

                if (lastName==nil) {
                    [self.LastName addObject:@""];
                } else {
                     [self.LastName addObject:lastName];
                }
            }
