UIPicker selection from NSUserDefaults in double value

Question

I'm beginner developer... I have NSUserDefaults to get UIPicker selection and a double value where to load selection of the UIPicker.

 NSUserDefaults *pickerViewSelectionDefaults = [NSUserDefaults standardUserDefaults];
        [pickerWork selectRow:[pickerViewSelectionDefaults integerForKey:@"pickerSelectionMinWork"] inComponent:0 animated:YES];

double dobMinute = [[NSString stringWithFormat:@"%f", [[minArray objectAtIndex:[pickerWork selectedRowInComponent:0]] floatValue]] doubleValue]*60;

How can I replace selectedRowInComponent: with selectRow:inComponent:animated: because I have this error:

Sending 'void' to parameter of incompatible type 'NSUInteger' (aka 'unsigned long')

Thanks in advance!
