Use an XIB for the subclass of tableViewCell, create a UIOutlet property for the UITextField, assign the subclass to the XIB’s class and wire up the UIOutlet property to the UITextField. Don’t forget to give the UITableViewCell an Identifier keyword.

Make sure to set the tableView to register the subclass for the cell if needed. I can dig up my working source, but it will be about 8 hours.

@interface TextTableCell : UITableViewCell
@property IBOutlet UITextField *textField;
@end


TableCellView.xib

File’s Owner = TextTableCell
Outlet textField = UITextField

View UIView contains
TextTableCell
Content View
UITextField


MyTableViewController

- (void)viewDidLoad
{
[super viewDidLoad];
UINib *nib = [ UINib nibWithNibName: @"TableCellView" bundle: nil ];
[ self.tableView registerNib: nib forCellReuseIdentifier: kTextCell ];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;
{
NSLog(@"%s will dequeueReusableCellWithIdentifier: \"%@\"",__FUNCTION__, cellId);
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: cellId forIndexPath: indexPath];
}


Result:

[tableView:cellForRowAtIndexPath:] will dequeueReusableCellWithIdentifier: "Cell with TextField"

I guess my TableCellView.xib is not quite right (or rather: absolutely messed up).
How to fix this?
