Populate UITableView with custom objects?

I am unsuccessfully trying to populate a UITable from a NSMutableArray that contains a custom object.

My Student object

Student {
     NSString name,
     int age
 }
 

In UITableView there is a method that displays the row's content:

cellForRowAtIndexPath
 {
     // there is more code here
     cell.textLabel.text = [tableData objectAtIndex:indexPath.row];
 }
 

Should my Student class implement a method that returns a String representation of the object? And then how can I display the content of the NSMutableArray in the UITableView.

Any help will be appreciated.
