How do I call the 'popoverControllerDidDismissPopover' method? - ios

Question

I am having trouble calling the the popoverControllerDidDismissPopover method in as much as I do not know where to put it and how to call it.
I have created a popover as follows -
// SettingsViewController.h
#import <UIKit/UIKit.h>
#import <QuartzCore/QuartzCore.h>
#import "ViewController.h"
#import "SharedData.h"
#import "PlayerPopUpVC.h"
#interface SettingsViewController : UIViewController <UITableViewDataSource, UIPopoverControllerDelegate> {
- (IBAction)popUp:(id)sender;
#property (strong, nonatomic) UIPopoverController *playerPopUpVC;
#property (strong, nonatomic) PlayerPopUpVC *popUp;
// SettingsViewController.m
#import "SettingsViewController.h"
- (IBAction)popUp:(id)sender {
UIButton *editPlayers = (UIButton *)sender;
if(self.playerPopUpVC) {
self.popUp= [[PlayerPopUpVC alloc] initWithNibName:#"PlayerPopUpVC" bundle:nil];
self.popUp=[[UIPopoverController alloc] initWithContentViewController:self.popUp];
}
[self.playerPopUpVC presentPopoverFromRect:[editPlayers frame] inView:[editPlayers superview] permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
I know I have to set the delegate of my PopOver to self in order to call the method but cannot work out what the code is.
I have tried -
self.playerPopUpVC.delegate=self
but Xcode does not like it.
My popOver class looks like this -
// PlayerPopUpVC.h
#import <UIKit/UIKit.h>
#interface PlayerPopUpVC : UIViewController <UITableViewDataSource, UIPopoverControllerDelegate> {
}
// PlayerPopUpVC.m
#import "PlayerPopUpVC.h"
#interface PlayerPopUpVC ()
#end
- (void)viewDidLoad
{
[super viewDidLoad];
self.modalInPopover = NO;
self.contentSizeForViewInPopover = CGSizeMake(240, 400);
}
Any help would be most welcome. I have spent a week now trying to sort it.

First, you need to understand the delegate pattern, which seems that you dont fully understand yet.
The popover will be the one which will call the popoverControllerDidDismissPopover method on the delegate. You only have to implement the UIPopoverControllerDelegate protocol in your class and assign yourself as the delegate of the popover. Why do you say that XCode doesn't like it? please, provide more info.
Furthermore, you are making an incorrect assignment here:
self.popUp=[[UIPopoverController alloc] initWithContentViewController:self.popUp];
Edit: Provided more code to help with the error. Please, review the delegate pattern next time before making these questions.
Your SettingsController.m should have this instead:
- (IBAction)popUp:(id)sender {
UIButton *editPlayers = (UIButton *)sender;
if(!self.popUp) {
self.popUp= [[PlayerPopUpVC alloc] initWithNibName:#"PlayerPopUpVC" bundle:nil];
}
self.playerPopUpVC=[[UIPopoverController alloc] initWithContentViewController:self.popUp];
self.playerPopUpVC.delegate = self;
[self.playerPopUpVC presentPopoverFromRect:[editPlayers frame] inView:[editPlayers superview] permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
- (void)popoverControllerDidDismissPopover:(UIPopoverController *)popoverController {
// Your code here
}
