Showing contact name and no. from address book, throwing exception NSInvalidArgumentException - ios

Question

I'm retrieving Contact name and phone no. from the Address book in my application. I'm printing them in log and it is working fine. But when I try to show them on the table view, I'm getting the exception NSInvalidArgumentException. I have a button on the view controller, pressing which the table view should get populated with the contact names and their no.s:
- (IBAction)syncContacts:(id)sender
{
ABAddressBookRef addressBook = ABAddressBookCreate();
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);
for (int i = 0; i < ABAddressBookGetPersonCount(addressBook); i++) {
ABRecordRef ref = CFArrayGetValueAtIndex(allPeople, i);
NSString *contact = (NSString *)CFBridgingRelease(ABRecordCopyCompositeName(ref));
// NSString* phone = nil;
ABMultiValueRef phoneNumbers = ABRecordCopyValue(ref,kABPersonPhoneProperty);
// if (ABMultiValueGetCount(phoneNumbers) > 0) {
NSString *phone = (__bridge_transfer NSString*)
ABMultiValueCopyValueAtIndex(phoneNumbers, 0);
// }
NSDictionary *curContact=[NSDictionary dictionaryWithObjectsAndKeys:(NSString *)contact,#"Name",phone,#"phone",nil];
[self.phoneContacts addObject:curContact];
}
tableView.delegate = self;
tableView.dataSource = self;
[tableView reloadData];
NSLog(#"%#",self.phoneContacts);
NSLog(#"%i",[self.phoneContacts count]);
}
And the table view methods are:
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [self.phoneContacts count];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
// cell.textLabel.text = [self.phoneContacts objectAtIndex:indexPath.row];
cell = [self.phoneContacts objectAtIndex:indexPath.row];
return cell;
}
What's wrong with the table view? When the phoneContacts had only the name, it was working fine.([phoneContacts addObject:contact]). But now when I'm adding the dictionary object, it is throwing this exception.
I've made a change.
cell = [[self.phoneContacts objectAtIndex:indexPath.row] objectForKey:#"AddressBook"];
The exception doesn't come now. But nothing is getting shown on screen.
Here's the edited method:
- (IBAction)syncContacts:(id)sender
{
ABAddressBookRef addressBook = ABAddressBookCreate();
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);
for (int i = 0; i < ABAddressBookGetPersonCount(addressBook); i++) {
ABRecordRef ref = CFArrayGetValueAtIndex(allPeople, i);
// NSNumber *contact = (NSNumber *)ABRecordCopyComposite();// (ref));
NSString *contact = (NSString *)CFBridgingRelease(ABRecordCopyCompositeName(ref));
// NSString* phone = nil;
ABMultiValueRef phoneNumbers = ABRecordCopyValue(ref,kABPersonPhoneProperty);
// if (ABMultiValueGetCount(phoneNumbers) > 0) {
NSString *phone = (__bridge_transfer NSString*)
ABMultiValueCopyValueAtIndex(phoneNumbers, 0);
// }
// NSDictionary *curContact=[NSDictionary dictionaryWithObjectsAndKeys:(NSString *)contact,#"Name",phone,#"phone",nil];
contact = [contact stringByAppendingString:#" "];
contact = [contact stringByAppendingString:phone];
[self.phoneContacts addObject:contact];
}
tableView.delegate = self;
tableView.dataSource = self;
[tableView reloadData];
}
The table view remains unchanged as given in the original post. It is now working.

The commented line cell.textLabel.text = [self.phoneContacts objectAtIndex:indexPath.row]; doesn't work? Can you set breakpoint and check if the cell's textlabel have the text assigned?
Assigning the cell using
cell = [[self.phoneContacts objectAtIndex:indexPath.row] objectForKey:#"AddressBook"]
wouldn't work, unless you defined phoneContacts to be subclass of UITableViewCell.
