Getting a popOver from a popover for an ios application

Question

My scenario is like this. I have a tableview cell which has a button.If fire it menu will popout like below

for the above menu popover the source is the button that is appearning extreme right of each cell.

I have another table view called diplayAccounts. on click of the popover menu's cell (i.e. view hierarchy) the displayAccounts View controller needs to be displayed as a popover. My doubt is that what should be the source for it.

    override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
menuTapped(self)
} 

the method menuTapped is as follows

func menuButtonTapped(sender: AnyObject)
{
    let storyboard : UIStoryboard = UIStoryboard(name: "Storyboard", bundle: nil)
    let vc = storyboard.instantiateViewControllerWithIdentifier("HierarchyTableViewController") as! HierarchyTableViewController
    vc.modalPresentationStyle = UIModalPresentationStyle.Popover
    let popover: UIPopoverPresentationController = vc.popoverPresentationController!
    popover.sourceView = sender as? UIView
    popover.delegate = self
    presentViewController(vc, animated: true, completion:nil)
}

And the error that I'm getting

Please help me.

Answer 1

Its not good idea to present pop over inside another popover(From Apple Mobile Human Interface Guidelines)

The best thing you can do is like

In pop over view controller class

• Implement a delegate protocol in the view controller class that displays the list of items as you shown in the attachment.
• Inside that delegate protocol, add a call back method with the params to contain the details of the selected cell.
• Add delegate property in the view controller of the popover class.
• Call the delegate method from the cell selection event.

In cell class that displays the button from which popover is presented

(i.e. the cell displaying 44087 and 111 in the picture above)

• Initialise the delegate object before presenting pop over
• Implement the delegate method declared in the delegate protocol to get the selection event.

• Show the other pop over you wanted.

  UPDATE

This will be the popover view controller that displays list of items as you shown above

PopOverWithListItemsViewController.h file

#import <UIKit/UIKit.h>

@protocol PopoverWithListItemsViewDelegate <NSObject>

- (void)didSelectedListItemAtIndex:(NSInteger)index;

@end

@interface PopOverWithListItemsViewController : UIViewController

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

@end

In table view selection event, add the delegate call like

NSInteger indexOfSelectedItem =  4;// jus for demo setting index as 4
[self.delegate didSelectedListItemAtIndex:indexOfSelectedItem];

And in the class from which you presenting list popover, add the following

Step1

The class from which you present the pop over should confirm to the delegate like follows

@interface ViewController () <PopoverWithListItemsViewDelegate> // let ViewController is the class from which you presenting the pop over

Step2

// Let this be the cell's button tap event from which you presenting the pop over
- (IBAction)buttonTapEvent:(id)sender
{
  // Presenting pop over sections
  PopOverWithListItemsViewController *listItemsPopOverVC = [[PopOverWithListItemsViewController alloc] init];
  listItemsPopOverVC.delegate = self;
  // pop over presenting with listItemsPopOverVC as popover's view controller
}

Step3

// Delegate method implementation.
- (void)didSelectedListItemAtIndex:(NSInteger)index
{
  // Here we get the index of the selected cell in the popover.
  // Present the new popover from here, after customizing the new pop over contents.
}
