Ipad PopOverview控制器的框架

我显示了一个

PopoverViewController

，但无法正确设置其帧。当我点击一个按钮时，将显示我的

PopoverViewController

-(IBAction)AddTheTimePicker:(id)sendar {

    if(UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPad)
    {

        UIButton *button = (UIButton *)sendar;
        [button setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];

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

       DatePicker=[[[UIDatePicker alloc]init]autorelease];//Date picker
        DatePicker.frame=CGRectMake(0,44,320, 216);
      DatePicker.datePickerMode = UIDatePickerModeDate;
        [DatePicker setTag:10];

        UIToolbar *pickerDateToolbar = [[[UIToolbar alloc] initWithFrame:[self isViewPortrait]?CGRectMake(0, 0, 320, 44):CGRectMake(0, 0, 320, 44)]autorelease];
        pickerDateToolbar.barStyle = UIBarStyleBlackOpaque;
        [pickerDateToolbar sizeToFit];

        NSMutableArray *barItems = [[[NSMutableArray alloc] init]autorelease];

        UIBarButtonItem *doneBtn = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(dateChanged:)]autorelease];

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

        UILabel *toolBarItemlabel;
        if([self interfaceOrientation] == UIInterfaceOrientationPortraitUpsideDown || [self interfaceOrientation] == UIInterfaceOrientationPortrait)
            toolBarItemlabel= [[[UILabel alloc]initWithFrame:CGRectMake(0, 0, 180,30)]autorelease];
        else
            toolBarItemlabel = [[[UILabel alloc]initWithFrame:CGRectMake(0, 0, 200,30)]autorelease];
        [toolBarItemlabel setTextAlignment:UITextAlignmentCenter];
        [toolBarItemlabel setTextColor:[UIColor whiteColor]];
        [toolBarItemlabel setFont:[UIFont boldSystemFontOfSize:16]];
        [toolBarItemlabel setBackgroundColor:[UIColor clearColor]];


        UIBarButtonItem *buttonLabel =[[[UIBarButtonItem alloc]initWithCustomView:toolBarItemlabel]autorelease];

        [barItems addObject:buttonLabel];

        [barItems addObject:flexSpace];

        UIBarButtonItem *SelectBtn = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(DatePickercancelClick:)]autorelease];
        [barItems addObject:SelectBtn];

        [pickerDateToolbar setItems:barItems animated:YES];

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

        [popoverController setPopoverContentSize:CGSizeMake(320, 264) animated:NO];



        [popoverController presentPopoverFromRect:[sendar frame] inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];


    }
}

ui按钮

的框架是

。我想在这个按钮下面显示一个箭头标记指向按钮的弹出框。但是我得到了这样的结果：

我怎样才能得到它呢？

除了自己制作外，还有很多定制的popover，可以满足您的所有需求。我已经使用了我认为简单而有用的许可证，在计划将其用于您的项目之前，请不要忘记检查许可证。

尝试以下方法：-

   -(IBAction)products:(id)sender{
UIButton* btn = (UIButton *)sender;
[productsPopover presentPopoverFromRect:[btn bounds] inView:btn permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
  }

我该怎么使用这些爆米花呢？
