Question

我通过集成8段的分段控件，以编程方式创建了动态表的自定义单元格。

它运行良好但是一旦我点击其中一个片段，我希望在单元格附近出现带有选项的弹出菜单，而不是在tableview的低端。

我认为这是因为我将segue锚定到tableview。我想避免为每个段分配一个到弹出菜单的segue。

是否有可能根据所选的段自动重新定位弹出菜单？

以下是主视图控制器.m文件中的相关代码

-(void)segmentSelectedAtRow: (UISegmentedControl *)sender{
if (self.flipsidePopoverController) {
    [self.flipsidePopoverController dismissPopoverAnimated:YES];
    self.flipsidePopoverController = nil;
} else {
    [self performSegueWithIdentifier:@"segueToChangeValues" sender:sender];
}

UITableViewCell *theParentCell = [[sender superview]superview];
NSIndexPath *indexPathOfSegment = [self.spreadSheetView indexPathForCell:theParentCell];

...
}

...

- (void)flipsideViewControllerDidFinish:(POTFlipsideViewController *)controller {

[self.flipsidePopoverController dismissPopoverAnimated:YES];
self.flipsidePopoverController = nil;
}

- (void)popoverControllerDidDismissPopover:(UIPopoverController *)popoverController {
self.flipsidePopoverController = nil;
}

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue identifier] isEqualToString:@"segueToChangeValues"]) {
    [[segue destinationViewController] setDelegate:self];
    UIPopoverController *popoverController = [(UIStoryboardPopoverSegue *)segue popoverController];
    self.flipsidePopoverController = popoverController;
    popoverController.delegate = self;
}
}

@end

这是翻转.h文件

@class POTFlipsideViewController;

@protocol POTFlipsideViewControllerDelegate
- (void)flipsideViewControllerDidFinish:(POTFlipsideViewController *)controller;
@end

@interface POTFlipsideViewController : UIViewController

@property (weak, nonatomic) id <POTFlipsideViewControllerDelegate> delegate;

- (IBAction)done:(id)sender;
....
 @end

这是flipside .m文件的相关代码

#import "POTFlipsideViewController.h"

@interface POTFlipsideViewController ()

@end

@implementation POTFlipsideViewController

- (void)awakeFromNib
{
self.contentSizeForViewInPopover = CGSizeMake(320.0, 480.0);
 [super awakeFromNib];
 }

 - (void)viewDidLoad
{
    [super viewDidLoad];

}
return YES;
}

 - (IBAction)done:(id)sender
 {
    [self.delegate flipsideViewControllerDidFinish:self];
}

@end
