Try like this

NSUserDefaults *usrDefaults = [NSUserDefaults standardUserDefaults]; 

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{

    [usrDefaults setInteger:row forKey:@"Index"];
}

[pickerView selectRow:[[NSUserDefaults standardUserDefaults]integerForKey:@"Index"] inComponent:0 animated:NO];
