You can easily write following code to select first row in pickerView as give code below.

 [picker selectRow:0 inComponent:0 animated:YES];

set this code in your done button action.Here picker is pickerView outlet

you can also use delegate method to select row as

picker.delegate=self;

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
    NSLog(@"selected row is %i",row);
}

prefer this link Select first row

no, its not working :( if (self.topUpOperatorView) { [self.topUpPickerView selectRow:0 inComponent:0 animated:YES]; [self myViewDown:self.topUpOperatorView]; [self.topUpOperatorView removeFromSuperview]; } – Zeeshan Shaikh May 18 '13 at 05:54
I am not able to understand your entire code please paste it in pastebin.com and give me the link – Prince Kumar Sharma May 18 '13 at 05:56
are you sure it is getting entered in self.topUpOperatorView condition.Try applying NSLog in this condition. – Prince Kumar Sharma May 18 '13 at 05:58
use this operatorScratchPicker instead of topUpPickerView to select row – Prince Kumar Sharma May 18 '13 at 06:53
where you have declared topUpAmountPickerView and is it added to pickerView UI – Prince Kumar Sharma May 18 '13 at 06:55
