ios 6 strange behavior on custom UITableViewCell initialization

Question

I have custom and very simple UITableViewCell. I just want to init my table view by using new technique in ios 6, i.e. registering class and after deque cell with identifier. So i have UITableViewController, inside the tableview i have one prototype cell , here is the image of it.

at first i forgot to register the class in viewDidLoad method inside the Table View controller and it was working fine. here is the code.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    CustomCell *cell = [tableView  dequeueReusableCellWithIdentifier:@"customCellIdentifier" forIndexPath:indexPath];

    return cell;
}

but in this case

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier

is not called during the cell init process.

and the after i put the register class functionality inside the viewdidload. here is the code

- (void)viewDidLoad
{
    [super viewDidLoad];

    [self.tableView registerClass:[CustomCell class] forCellReuseIdentifier:@"customCellIdentifier"];

}

after it the - (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier starts invoking but in this case the cells are absolutely empty when i'm trying to debug , inside the initwithstyle method all the outlets are nil. whats going on? what i'm doing wrong?

Answer 1

If you have defined the cell as prototype cell for the table view in your nib/storyboard file, then you don't have to register it, that is done automatically. But in that case, initWithCoder: is called for cells instantiated from the nib/storyboard.
