If I understood your question correctly, you did a custom nib file for your cells that has 2 UILabel in it and one UITextField, and you want to access these objects when populating your table. Here are some steps for this issue:
First, you have to give a tag number for each object in your custom cell. You find this property in the Attribute Inspector in Interface Builder. Say you gave the first label tag 1, the second label 2 and the text field 3.
Second you have to give a. Identifier for this nib file, for example MyCustomCellIdentifier. This identifier will be used later on in the view that has the table so you can link to it.
Third, also in the custom cell nib, you click on the yellow square that says File's Owner and in the Identity Inspector you change the Class to the class name that has the table that will use this custom cell.
Fourth, in the class that you have the table that will use the custom cell, create an outlet of type UITableViewCell. We will link this in the custom nib cell.
Fifth, goto the custom nib cell, click on the cell window, then in the Connections Inspector link New Referencing Outlet to the File's Owner, you will see the outlet that you created in the table class showing here, simply link to it.
Now since the connections are established thing are more easy, in the cellForRowAtIndexPath function (in the class that contains the table for sure), you have to load the custom cell from the nib file as follows:
static NSString *tableIdentifier = #"MyCustomCellIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:tableIdentifier];
if(cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"TheNibClassNameOfYourCustomCell" owner:self options:nil];
if([nib count] > 0) cell = theNameOfTheOutletYouUsed;
else NSLog(#"Failed to load from nib file.");
}
Ok, your custom cell is loaded in variable cell, now you have to access every object in it from the tags you created:
UILabel *label1 = (UILabel *)[cell viewWithTag:1];
UILabel *label2 = (UILabel *)[cell viewWithTag:2];
UITextField *textField1 = (UITextField *)[cell viewWithTag:3];
Now you can access everything through label1, label2, and textField1 easily like label1.text = #"Hi";
I hope this answers your question.
