How to dismiss the UIPopoverController?

Question

I have created a UIPopoverController and added it to a view controller when clicking an UIButton as follows

- (void)viewDidLoad
{
    [super viewDidLoad];
    controller = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:[NSBundle mainBundle]];
    popoverController = [[UIPopoverController alloc] initWithContentViewController:controller];
}

- (IBAction)showPopover:(UIButton *)sender
{
    if ([popoverController isPopoverVisible]) {
        [popoverController dismissPopoverAnimated:YES];
    } else {
               CGRect popRect = CGRectMake(self.btnShowPopover.frame.origin.x,
                                self.btnShowPopover.frame.origin.y,
                                self.btnShowPopover.frame.size.width,
                                self.btnShowPopover.frame.size.height);
          [popoverController presentPopoverFromRect:popRect
                                       inView:self.view
                     permittedArrowDirections:UIPopoverArrowDirectionAny
                                     animated:YES];
    }
}

btnShowPopover is the UIButton in the viewcontroller, popoverController is the UIPopoverController.

The popovercontroller appears fine while clicking the button.

But it won't get dismissed when I click the UIButton in the secondviewcontroller

I used the following code for that

-(IBAction)y:(id)sender{
    fs =  [[Firstviewcontroller alloc] initWithNibName:@"FIrstscreen" bundle:[NSBundle mainBundle]];
    [fs.popoverController dismissPopoverAnimated:TRUE];
}

But it didn't work.

How to dismiss the popovercontroller when clicking the button in a viewcontoller that was added to the popovercontroller?

Solution 1

You are allocating a new instance of Firstviewcontroller, so it won't dismiss the previous instance's popover.

You need to pass the old instance when you are displaying the popover like:

- (void)viewDidLoad
{
    [super viewDidLoad];
    controller = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:[NSBundle mainBundle]];
    popoverController = [[UIPopoverController alloc] initWithContentViewController:controller];
    [controller setFs:self]
}

And dismiss like:

-(IBAction)y:(id)sender
{
    [fs.popoverController dismissPopoverAnimated:TRUE];
}

Solution 2

Apple docs:

The popover controller does not call this method in response to programmatic calls to the dismissPopoverAnimated: method. If you dismiss the popover programmatically, you should perform any cleanup actions immediately after calling the dismissPopoverAnimated: method.

So the didDimiss delegate's method won't be called by itself.

Try:

[self.popover dismissPopoverAnimated:YES];
[self.popover.delegate popoverControllerDidDismissPopover:self.PopUp];

it's not the case here, he is initializing new instance for dismissing the old popover

[Nazik]

[controller setFs:self], it gives an error, How to pass the old instance when displaying the popover

[Midhun MP]

@NAZIK: still have issues ?

[Nazik]

@ Midhun MP, yes,error - popovercontroller not found on object of type 'PopOverViewController *'- what to do now?

[Midhun MP]

@NAZIK: please check your code once again, I think you made a mistake. Check whether you are passing [... setFS:self] and check the typr of fs, it should be Firstviewcontroller

[Midhun MP]

declare the fs in your SecondViewController class's @interface and create a property @property (nonatomic, assign) Firstviewcontroller *fs; if you are using non-arc and synthesize it

[Midhun MP]

@NAZIK: my mistake, please check above comment. Type of fs is Firstviewcontroller

[Nazik]

U said " Check whether you are passing [... setFS:self] and check the typr of fs" where to write this and what is 'setFS'

[Nazik]

When writing [controller setFS:self]; it gives an error- No visible @interface for 'PopoverViewController' declares the selector 'setFS:'

[Midhun MP]

your controller is of type SecondViewController is it ?

[Midhun MP]

I told you to put @property (nonatomic, assign) Firstviewcontroller *fs; this code on your SecondViewController's @interface. Did you do that ?

[Nazik]

yes I did it, and [fs.popoverController dismissPopoverAnimated:TRUE]; throws no error but it didnot dissmiss the popover

[Nazik]

what is [controller setFs:self]

[Midhun MP]

controller is the instance of your SecondViewController and you are setting the firstviewcontroller instance to fs using the setter method

[Midhun MP]

@NAZIK: Ok, please share that

[Nazik]

Hi Midhun, take a look at my question, pl answer if you can.

[Midhun MP]

@NAZIK: I added a comment in your question, please check. It'll work. I think you already got that answer

[Nazik]

Thanks for info, I got the solution.
