Set text to textfield of table Cell in objective c outside UITableView delegate methods

I am new to objective C,and have made a demo app.

In this app I am having a UITableView which contains textField.When I taps a button(sign in using Facebook), after successfully login from Facebook it come back to my TableView screen,at that time i want to set values came from Facebook response to UITableView's textFields, but I am unable to do it as TableView's delegate method is calling only once.

Can anybody please help me to set text to tableView's textField outside its delegate method?


NSString *cellIdentifier = [[signInTableData objectAtIndex:2] objectForKey:@"cellIdentifier"];

signUpCustomCell *cell = (signUpCustomCell *)[signUpTable dequeueReusableCellWithIdentifier:cellIdentifier];
//NSLog(@"=====my username cell====%@",indexPath);
if(cell == nil)
cell = (signUpCustomCell *)[[signUpCustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
cell.backgroundColor = [UIColor clearColor];
cell.tableField.delegate = self;

CGRect frmTxt = cell.tableField.frame;
frmTxt.size.width = signUpTable.frame.size.width + TRAIL_MARGIN_CELL_CONTENT;
cell.tableField.frame = frmTxt;
cell.tableField.text = @"hello test";

If you know at which row your UITextField is then you can query UITableView for a cell at given IndexPath.

NSIndexPath *ip = [NSIndexPath indexPathForRow:0 inSection:0];
UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:ip];

You'll need to cast that cell to what ever custom cell you are using to access the UITextField inside and your custom UITableViewCell should have a property that points to the UITextField or a method that would update the text.

-(void)viewWillAppear or -(void)viewDidApper overrides in your UIViewController subclass could be the places to do that, after you have loaded your data to the UITableView.
