Implement UITextField delegate and set tag value to all your textField in series. like 1,2,3..as so on. then, make sure scrollView and textField tag values should not conflict.

-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
    int nextTextFieldTag = textField.tag+1;
    UITextField *textFieldd = (UITextField*)[self.view viewWithTag:nextTextFieldTag];
    if (textFieldd!=nil) {
        if ([textField isKindOfClass:[UITextField class]]) {
            [textFieldd becomeFirstResponder];
            return NO;
        }
    }
    return YES;
}

in additionally , i have a button for saving information after textfields, so in last that function should be executed automatically thanks – Harendra Tiwari Aug 14 '13 at 11:02
I have a few concerns with your code. 1) Not really a concern more of general wondering, what is scr? 2) What would you do if I have a `UITextField` with a tag of 2 and I have a `UIView` with a tag of 2, which one would it return for `viewWithTag`? How would you handle this sort of situation? Where is the check to make sure that it is a `UITextField`? – Popeye Aug 14 '13 at 14:57
@Popeye scr is scrollView.... – Rajneesh071 Aug 16 '13 at 06:01
@Rajneesh071 I still have concerns about the `viewWithTag` but this would work. – Popeye Aug 16 '13 at 08:00
@Popeye make sure scrollView and textField tag values should not conflict. – Rajneesh071 Aug 16 '13 at 10:33
Not a fan this but I suppose it is a solution. – Popeye Aug 16 '13 at 11:05
@Popeye you can check now... :). – Rajneesh071 Aug 16 '13 at 11:11
Adding the check in makes it better :-) +1 – Popeye Aug 16 '13 at 11:12
where is +1 , you just removed your down vote... :) – Rajneesh071 Aug 16 '13 at 11:17

Try this

Take the 4 textfields as textfield1,textfield2,textfile3,textfield4 .

In the textfield delegate method

 - (BOOL)textFieldShouldReturn:(UITextField *)textField 
{

    if([textField isEqual:textfield1]) 
    {
     [textfield2 becomeFirstResponder];
      return NO;
    }

    else if([textField isEqual:textfield2]) 
    {
     [textfield3 becomeFirstResponder];
      return NO;
    }

        // Do for other textfields
    return YES;
}

This won't work. Because the nextTextfield will never be the current one returning ;) – lukaswelte Aug 14 '13 at 09:54

You just need to know what the next TextField should be and have UITextFieldDelegateProtocol especially the - (BOOL)textFieldShouldReturn:(UITextField *)textField implemented.

In - (BOOL)textFieldShouldReturn:(UITextField *)textField simply figure out the next TextField and do [nextTextField becomeFirstResponder];

So the - (BOOL)textFieldShouldReturn:(UITextField *)textField Method could look like this:

- (BOOL)textFieldShouldReturn:(UITextField *)textField 
{

    if ([textField isEqual:firstTextField]) {
        [secondTextField becomeFirstResponder];
    } 

    //When last textfield dismiss the keyboard
    else if ([textField lastTextField]) {
        [textField resignFirstResponder];
    }

    return NO;
}
