You might want to be more specific next time you ask a question.
You can try assign a different tag for each button in interface builder (or the same tag if thats what you need) and then use the following code
for (int i = 1 ; i<=10;i++)
{
UIButton *myButton = (UIButton *)[myView viewWithTag:i];
[myButton setTitle:@"my text" forState:UIControlStateNormal];
}
