Question

我正在尝试在表委托方法（DidSelectRowAtIndex）中打开ABPersonViewController。但是当我在表视图中点击我的一个联系人时，它会显示“obj msg send”。帮我这是我的代码：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    // Fetch the address book 
    if ((people != nil) && [people count])
    {   

        ABAddressBookRef addressBook = ABAddressBookCreate();
        //ABPersonViewController *personController = [[ABPersonViewController alloc] initWithNibName:@"ABPersonViewController" bundle:nil];

        ABRecordRef person = (ABRecordRef)[people objectAtIndex:indexPath.row];     
        ABPersonViewController *personController = [[ABPersonViewController alloc] init];

        personController.addressBook = addressBook;
        personController.personViewDelegate = self;
        personController.displayedPerson = person;
        personController.allowsEditing = YES;       
        //navigationController = [[UINavigationController alloc] init] ;
        [self presentModalViewController:personController animated:YES];
        //[self.navigationController pushViewController:personController animated:YES];
        [personController release];     
    }   else 
    {
        // Show an alert if "KETAN" is not in Contacts
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" 
                                                        message:@"Could not find naina in the Contacts application" 
                                                       delegate:nil 
                                              cancelButtonTitle:@"Cancel" 
                                              otherButtonTitles:nil];
        [alert show];
        [alert release];
    }
    [people release];

}

Answer 1

你在这里做了一个不必要的发布，CFRelease(person);。您只是直接从数组中获取值，因此您不应该释放它。此外，ABPersonViewController对象不会保留分配给person的{{1}}对象，因此在尝试访问已释放的对象时会导致错误。

Answer 2

如果您希望人物视图在编辑模式下打开，除了allowsEditing = YES之外，您还需要指定setEditing:YES：

[personController setEditing:YES animated:NO];

Answer 3

使用此行而不是代码中的行

ABPersonViewController *personController = [[ABPersonViewController alloc] initWithNibName:@"ABPersonViewController" bundle:nil];

不要打开A Person ViewController
