ios - 在 UIViewController 中创建没有箭头并居中的 PopOver

Question

我正在尝试在横向方向的 ipad 中心显示一个 PopOver。我现在可以使用下面的代码来完成它，但它没有与 Storyboard上链接的“popOverViewController”相关联的属性。我希望它成为 Storyboard上的一个 View ，以便我能够处理和编辑它。以及能够将其大小更改为 ipad 全 View 的 50% 或 75%，并且没有箭头...

拜托，任何事情都会有所帮助。 *更新代码....现在可以设置大小。但是仍然没有看到“popOverViewController”的内容。

self.popOverViewController = [[PopOverViewController alloc]init];
self.popOver = [[UIPopoverController alloc]
                            initWithContentViewController:self.popOverViewController];
CGSize size = CGSizeMake(400.0,300.0);
[self.popOver setPopoverContentSize:size];
CGRect rect = CGRectMake(self.view.frame.size.width/2, self.view.frame.size.height/2, 1, 1);
[self.popOver presentPopoverFromRect:rect inView:self.view permittedArrowDirections:0 animated:YES];

只需复制粘贴下面的代码

UIViewController *popovercontroller=[[UIViewController alloc] init];
UIView *popoverView=[[UIView alloc] initWithFrame:CGRectMake(312,390, 400, 344)];
popoverView.backgroundColor=[UIColor whiteColor];

popovercontroller.contentSizeForViewInPopover=CGSizeMake(400, 300);



UIDatePicker *pickerView = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 44, 400, 0)];
[pickerView setTintColor:[UIColor blackColor]];
[pickerView addTarget:self action:@selector(dueDateChanged:) forControlEvents:UIControlEventValueChanged];

pickerView.datePickerMode = UIDatePickerModeDate;
pickerView.hidden = NO;
NSString *bs ; //= [NSString alloc];
//    //NSDate *newDate = [NSData alloc];
bs =  CurrentSelectedDate;
if (bs.length >= 1) {
    NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init] ;
    //        //[dateFormatter setDateStyle:NSDateFormatterLongStyle];
    //        [dateFormatter setTimeStyle:NSDateFormatterNoStyle];
    [dateFormatter setDateFormat:@"dd-MMM-yyyy"];
    // NSDate *myDate = [dateFormatter dateFromString: txtText.text];
    pickerView.date = [dateFormatter dateFromString: CurrentSelectedDate];

}
else
{
    pickerView.date = [NSDate date];
}
[popoverView addSubview:pickerView];



// pickerView.date = [dateFormatter dateFromString:txtText.text];
UIToolbar *pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 400, 44)];
pickerToolbar.barStyle = UIBarStyleDefault;
pickerToolbar.barTintColor=[UIColor colorWithRed:150.0f/255.0f green:91.0f/255.0f blue:129.0f/255.0f alpha:1.0f];

[pickerToolbar sizeToFit];
self.navigationController.toolbar.barTintColor = [UIColor colorWithRed:150.0f/255.0f green:91.0f/255.0f blue:129.0f/255.0f alpha:1.0f];
NSMutableArray *barItems = [[NSMutableArray alloc] init];

UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:self action:nil];
[barItems addObject:flexSpace];

UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(doneButtonPressed:)];
doneBtn.tintColor=[UIColor whiteColor];
[barItems addObject:doneBtn];

UIBarButtonItem *cancelBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(cancelButtonPressed:)];
 cancelBtn.tintColor=[UIColor whiteColor];
[barItems addObject:cancelBtn];

[pickerToolbar setItems:barItems animated:YES];


[popoverView addSubview:pickerToolbar];
popovercontroller.view=popoverView;

pickerViewPopup = [[UIPopoverController alloc] initWithContentViewController:popovercontroller];

[pickerViewPopup presentPopoverFromRect:CGRectMake(312, 212, 400, 344) inView:self.view permittedArrowDirections:0 animated:YES];
