Custom Delegate, dismiss popover from another view

I could use some help with custom delegates. I'm trying to make a protocol that sends a message to its delegate to dismiss the popover view. Here is what I'm trying.

In the popoverViewController.h

#import <UIKit/UIKit.h>


@protocol MyPopoverDelegate <NSObject>
-(void) didSelectLanguage;
@end



@interface Popover : UITableViewController{

    id <MyPopoverDelegate> delegate;
    NSMutableArray *languageData;

}

@property (nonatomic, assign) id <MyPopoverDelegate> delegate;

@end

.m

@synthesize delegate;

...

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSLog(@"You selected %@", [languageData objectAtIndex:[indexPath row]]);
    [self.delegate didSelectLanguage];

}

...

And in the ViewController that presents the popover

#import <UIKit/UIKit.h>
#import "popoverViewController.h"




@interface ChoicesChoices : UIViewController <UIPopoverControllerDelegate, MyPopoverDelegate>{

    UIPopoverController *popover;




}
- (IBAction)facebook:(id)sender;
- (IBAction)twitter:(id)sender;
- (IBAction)sms:(id)sender;
- (IBAction)copy:(id)sender;
- (IBAction)email:(id)sender;
- (IBAction)home:(id)sender;
- (IBAction)mute:(id)sender;
- (IBAction)note:(id)sender;


@property (nonatomic, retain) UIPopoverController* popover;


@end

and .m

@synthesize popover;

...

- (void)didSelectLanguage{
[popover dismissPopoverAnimated:YES];
NSLog(@"didSelectLanguage fired");
}

When I select a row in the table of the popover, didSelectLanguage does not get called. Any ideas on what I might be doing wrong? Thanks for your help.

Make sure you are setting your delegate to the be the view controller that is presenting your popover. Something like this in ChoicesChoices.m:

- (void)presentPopover
{
  // assuming ARC for all allocations
    Popover *myController = [Popover new];
    myController.delegate = self;
    self.popover = [[UIPopoverController alloc] initWithContentViewController:myController];
    [self.popover presentPopover...];  // two flavors here, FromRect: and FromBarButtonItem:, that's left up to you to choose which one is correct.
}

Make sure you set the delegate in the presenting view controller when you create the instance of your custom class. 

popover.delegate = self

Also, it looks like your property is a standard popover controller instead of an instance of your custom view controller.
