How to dismissPopoverAnimated on iPad with UIPopoverController in MKMapView (SDK3.2)

Question

I have a MKMapView (also a UIPopoverControllerDelegate) with Annotations. This MapView has, in the MKTestMapView.h file, a UIPopoverController* popoverCo

Answer 1

Here is another simple solution.

I found that we should follow the following steps for clearly dismissing popovers.

1. dismiss a popover.
2. release a view loaded by the popover.

Before iOS8, almost all of us may release a view loaded by a popover first, and then we programmatically dismiss the popover. However, in iOS8, we do the steps in revers.

Before iOS8, my code of dismissing a popover

// creating a popover loading an image picker
picker = [[UIImagePickerController alloc] init];
...
pickerPopover = [[UIPopoverController alloc] initWithContentViewController:picker];
[pickerPopover presentPopoverFromRect:aFrame inView:aView permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];

// dismissing the popover
[picker.view removeFromSuperview]; // (1) release a view loaded by a popover
[picker release], picker = nil;

if( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad ) {
    [pickerPopover dismissPopoverAnimated:YES]; // (2) dismiss the popover
}

In iOS8, the dismissing code part should be changed as below,

if( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad ) {
    [pickerPopover dismissPopoverAnimated:YES];  // (2) dismiss the popover first
}

[picker.view removeFromSuperview]; // (1) and then release the view loaded by the popover
[picker release], picker = nil;

Answer 2

I had the same problem... I had a neat "close" button (X) in the top of my view loaded by the popover, but it didn't work. In my universal app it will be presented as a new view, so that code should stay.

What I did now was that I added the following to my detailedPinView (the view the popover loads):

in the detailedPinView.h file:

@interface detailedPinView : UIViewController {
    [...]   
    UIPopoverController *popover;
    [...]
}

-(void)setPopover:(UIPopoverController*)aPopover;

In the detailedPinView.m file:

- (void)setPopover:(UIPopoverController*)aPopover
{
    popover = aPopover;
}

The X button closes the view using an IBAction, this is what I did there:

In the detailedPinView.m file:

-(IBAction)releaseDetailedView:(UIButton *)sender
{
    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
    {
        if (popover != nil)
        {
            [popover dismissPopoverAnimated:YES];
        }
        else {
            NSLog(@"Nothing to dismiss");
        }
    }
    else{
        [self.parentViewController dismissModalViewControllerAnimated: YES];
    }
}

In the class loading the my map and the popover view I added the following code:

[...]
-(void)mapView:(MKMapView *)theMapView annotationView:(MKAnnotationView *)pin calloutAccessoryControlTapped:(UIControl *)control
{   
    UIViewController *detailController = [[detailedPinView alloc] initWithNibName:@"detailedPinView" 
                                                                           bundle:nil 
                                                                   annotationView:pin];

    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
    {

        UIPopoverController* aPopover = [[UIPopoverController alloc] initWithContentViewController:detailController];
        [aPopover setDelegate:self];
        [aPopover setPopoverContentSize:CGSizeMake(320, 320) animated:YES];

        [detailController setPopover:aPopover];
        [detailController release];

        [mapView deselectAnnotation:pin.annotation animated:YES];

        self.popoverController = aPopover;

        [mapView setCenterCoordinate:pin.annotation.coordinate animated:YES];

        [self.popoverController presentPopoverFromRect:CGRectMake(382,498,0,0) inView:self.view  permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
    }
    else
    {
        [self presentModalViewController: detailController animated:YES];
    }


    [detailController release];
}
[...]

I don't know if the was the answer you were hoping for, I think it might be a bit of a messy way to do it... but giving the time schedule this worked like a charm :)
