Dismissing popover with a button

[mashercakes]

I'm trying to dismiss a popover with a button within the popover. I've tried this:

MainViewController *m = [[MainViewController alloc] init];
[m.myPopOver dismissPopoverAnimated:YES];
[m release];

However this doesn't work as the popover remains. Is what I'm trying to do even possible?

You made a completely new view controller and dismissed its popover. That doesn't make any sense. You need to dismiss the popover you already have.

Ok, that makes sense. So how do I reference the popOver which I am trying to dismiss?

You have to keep a reference to it. If your view controller already has a myPopOver property, put the popover in there before you show it.

MainViewController does have the myPopOver reference, and the popOver is created there ready to be displayed. The problem I'm having is working out how to refer back to it. I've just tried this:

[[(MainViewController*)self.parentViewController myPopOver] dismissPopoverAnimated: YES];

but again, the popover just stays there.

Ok, you're not providing enough structure here to figure this out.

Ok, I have figured this out now but I'll provide some more info for others who may find this post. myPopOver is defined in MainViewController.h:

//...

@interface MainViewController : UIViewController <UINavigationControllerDelegate, UIImagePickerControllerDelegate, UIPopoverControllerDelegate> {
	UIPopoverController *myPopOver;
	//...
}

@property (nonatomic, retain) UIPopoverController *myPopOver;
//...

@end

And gets created in MainViewController.m:

- (void)viewDidLoad {
	//...
	MyPopOverViewController *rc = [[MyPopOverViewController alloc] init];
	myPopOver = [[UIPopoverController alloc] initWithContentViewController:rc];
	[rc release];
	myPopOver.popoverContentSize = CGSizeMake(254, 95);
	myPopOver.delegate = self;

	//...

I have stopped the popover from automatically dismissing with the following in MainViewController.m:

- (BOOL)popoverControllerShouldDismissPopover:(UIPopoverController *)popoverController {
	return NO;
}

The key to getting the myPopOver to be able to dismiss itself was to give the PopOverController a "parent" property of type MainViewController, then set that to "self" when creating the PopOver in MainViewController. Then the following line dismisses the popOver from within myPopOver.m:

[parent.myPopOver dismissPopoverAnimated:YES];

Hello,

I understand the above statement, but I am new to Objective-C, if it is not to much trouble, can you post the code you used to create the "parent" in each .h and .m file. Thanx in advance.
