Ios 如何使用uitoolbar上的“完成”按钮在故事板中创建pickerview作为popover

我已经使用代码创建了上面的示例，但我想知道是否可以使用故事板实现同样的效果

我是ios的noob，我想知道怎么做。
提前谢谢

不带情节提要和“完成”按钮的代码：

UIViewController* popoverContent = [[UIViewController alloc] init]; //ViewController

UIView *popoverView = [[UIView alloc] init];   //view
popoverView.backgroundColor = [UIColor blackColor];

UIDatePicker *datePicker=[[UIDatePicker alloc]init];//Date picker
datePicker.frame=CGRectMake(0,44,320, 216);
datePicker.datePickerMode = UIDatePickerModeDateAndTime;
[datePicker setMinuteInterval:5];
[datePicker setTag:10];
[datePicker addTarget:self action:@selector(Result) forControlEvents:UIControlEventValueChanged];
[popoverView addSubview:datePicker];

popoverContent.view = popoverView;
popoverController = [[UIPopoverController alloc] initWithContentViewController:popoverContent];
popoverController.delegate=self;
[popoverContent release];

[popoverController setPopoverContentSize:CGSizeMake(320, 264) animated:NO];
[popoverController presentPopoverFromRect:tempButton.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];//tempButton.frame where you need you can put that frame
