Firstly add this delegates in interface:

 @interface yourViewController : UIViewController<UITextFieldDelegate>

If using from xib then right click on UITextField and bind delegate with fileowner else add this code in viewDidLoad's method.

  yourTextField.delegate = self;

Add UITextField's delegate and it will be called

 - (BOOL)textFieldShouldReturn:(UITextField *)textField //resign first responder for textfield 
 {
    [textField resignFirstResponder];
    return YES;
 }

 - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
 {
   return YES;
 }
