In my application I have a presentViewController, and inside it I have a button that opens a popover. In this popover I have a barButtonItem to save de data of this popover. I would like that when the user taps outside of the popover, the data could be saved too.
I've tried to use the popoverControllerDidDismissPopover method in the presentViewController view. I have the delegate but when I tap outside of the popover this method is not called.
What can I do?
Thanks!!
Add this line of code while adding popOver:
popover.delegate = self;
Also register popOverDelegate in .h file where u present your popOver COntroller
#interface yourViewController : UIViewController<UIPopoverControllerDelegate>
Please, pay attention to docs!
"Called on the delegate when the user has taken action to dismiss the popover.
This is not called when the popover is dismissed programmatically."
It was my case because my popover was closing on button tap with this method:
dismiss(animated: true, completion: nil)
You probably already solved it, but I just faced the same problem. I'm holding a instance of UIPopoverController in my Viewcontroller and had it this way:
self.popover.delegate = self;
self.popover = [[UIPopoverController alloc] initWithContentViewController:wgtvc];
of course this doesn't work because I'm initializing the UIPopoverController AFTER setting the delegate, which overrides the delegate setting. So the correct way is to FIRST initialize the UIPopovercontroller and THEN setting the delegate
self.popover = [[UIPopoverController alloc] initWithContentViewController:wgtvc];
self.popover.delegate = self;
Maybe you are reinitializing your UIPopoverController somewhere - just set the delegate again after reinitializing.
I had the same problem and I solved it by handling it different for iOS8.
Presentation code
UIViewController *searchViewController = [[UIViewController alloc] init];
[[searchViewController view] addSubview:_searchOptions];
[searchViewController setModalPresentationStyle:UIModalPresentationPopover];
[searchViewController setPreferredContentSize:CGSizeMake(500, 400)];
[_searchOptions setHidden:NO];
[_searchOptions setFrame:[[searchViewController view] bounds]];
[_searchOptions setAutoresizingMask:UIViewAutoresizingFlexibleWidthAndHeight];
if (CRIdiomToolsIsIOS8OrHigher())
{
UIPopoverPresentationController *popOverPresentationController = [searchViewController popoverPresentationController];
[popOverPresentationController setDelegate:self];
[popOverPresentationController setSourceView:[_searchOptionsButton disclosureView]];
[popOverPresentationController setSourceRect:[[_searchOptionsButton disclosureView] bounds]];
[self presentViewController:searchViewController animated:YES completion:nil];
}
else
{
UIPopoverController *popOverControler = [[UIPopoverController alloc] initWithContentViewController:searchViewController];
[popOverControler setDelegate:self];
[popOverControler setPopoverContentSize:CGSizeMake(500, 400)];
[popOverControler presentPopoverFromRect:[[_searchOptionsButton disclosureView] bounds] inView:[_searchOptionsButton disclosureView] permittedArrowDirections:UIPopoverArrowDirectionUp|UIPopoverArrowDirectionLeft animated:YES];
}
Delegate calls
#pragma mark Delegate Methods: UIPopoverControllerDelegate
- (void)popoverControllerDidDismissPopover:(UIPopoverController *)popoverController
{
[self showSearchOptions:NO animated:YES];
}
#pragma mark Delegate Methods: UIPopoverPresentationControllerDelegate
- (void)popoverPresentationControllerDidDismissPopover:(UIPopoverPresentationController *)popoverPresentationController
{
[self showSearchOptions:NO animated:YES];
}
I had the same issue. You will need to retain the popover object, that way the delegate method gets called. Its strange but it works.
#property (nonatomic, retain) UIPopoverController *popupObject;
UIPopoverController *popup = [[UIPopoverController alloc] initWithContentViewController:viewController];
popup.delegate = self;
[popup presentPopoverFromRect:presentationRect inView:self permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
self.popupObject = popup; //Retained
-(void) popoverControllerDidDismissPopover:(UIPopoverController *)popoverController
{
//Do whatever operation you need to perform
self.popupObject = nil;
}
I know this questions is old but hopefully it helps someone out there...
The issue is in the initialization of your popover controller. If you have established the popover segue in the storyboard you need to have a reference to this popover in order for the delegate to be called when it is dismissed.
In your prepare for segue method:
Instead of:
self.popoverController = [[UIPopoverController alloc]initWithContentViewController:segue.destinationViewController];
self.popoverController.delegate = self;
You need:
self.popoverController = [(UIStoryboardPopoverSegue *)segue popoverController];
self.popoverController.delegate = self;
Then make sure to correctly handle if the when the popover should appear in
(BOOL)shouldPerformSegueWithIdentifier:(NSString *)identifier sender:(id)sender

I'm trying to detect when a UIPopoverController gets dismissed, but it seems not to work properly, the methods are not getting called. This is my code for presenting the UIPopoverController:
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePickerController.delegate = self;
UIPopoverController *popoverVC = [[UIPopoverController alloc] initWithContentViewController:imagePickerController];
popoverVC.delegate = self;
[popoverVC presentPopoverFromRect:CGRectMake(self.frame.origin.x,self.frame.origin.y, self.frame.size.width, self.frame.size.height) inView:[home view] permittedArrowDirections:0 animated:YES];
I'm trying to fire this method, but is not getting called:
- (void) popoverControllerDidDismissPopover:(UIPopoverController *) popoverController;
And I'm indeed adding the delegate to the header:
#interface Map : UIView <UIImagePickerControllerDelegate, UINavigationControllerDelegate, UIGestureRecognizerDelegate, UIScrollViewDelegate,UIPopoverControllerDelegate>
I don't know what I'm missing out, is not working at all.
You probably already solved it, but I just faced the same problem. I'm holding a instance of UIPopoverController in my Viewcontroller and had it this way:

Hpoe this helps.
So, I figured out how to make it work.
I made a "global" variable for the class.
self.popoverVC = [[UIPopoverController alloc] initWithContentViewController:imagePickerController];
self.popoverVC.delegate = self;
Because it's an UIImagePickerController inside a UIPopoverController, I needed to listen to the UIImagePickerController for dismission too and combine both methods:
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker;
- (void) popoverControllerDidDismissPopover:(UIPopoverController *) popoverController
So I can now detect when the UIPopoverController gets dismissed.
I'm currently building an iPad app in which I need to implement a pop over view.
I have set up a view controller like I always do:
Create UIViewController wit xib file
set the xib up and do the necessary programming in it's .h & .m files
now in the view controller I'm loading it from (from a UIBarButtonItem), I have this code:
- (void) action
{
ItemContent *newItem = [[ItemContent alloc] initWithNibName:#"ItemContent" bundle:nil];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:newItem];
_popover = [[UIPopoverController alloc] initWithContentViewController:nav];
[_popover setPopoverContentSize:CGSizeMake(557, 700) animated:YES];
_popover.delegate = self;
[_popover presentPopoverFromBarButtonItem:self.navigationItem.rightBarButtonItem permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
}
This properly displays my view- and UINavigationController in a UIPopOverController. So far so good!
In the newItem view controller, I have made a bar button in my navigation bar that says "Done". When that button is pushed, I want the UIPopOverController to disappear. How do I do this:
Set a method for when te button is pushed. In this method I want to call a function on the view controller that loaded the Popover to dismiss it again.. but how do I do this?
Put things shortly
How do I make my UIPopOverController call a method on the view controller that loaded the UIPopOverController?
I have been searching SO for a while but none of the solutions and answers solve my problem. If I missed something please inform me ;)
Thank you so much in advance!
You can do this by delegate...
In NewItem.h declare a protocol
#protocol NewItemDelegate
-(void)onTapDoneButton;
#end
Now create a delegate property like this
#property (nonatomic, assign) id<NewItemDelegate>delegate;
In NewItem.m in doneButtonPuhsed method call this
[self.delegate onTapDoneButton];
Change this method a bit
- (void) action
{
ItemContent *newItem = [[ItemContent alloc] initWithNibName:#"ItemContent" bundle:nil];
newItem.delegate =self;
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:newItem];
_popover = [[UIPopoverController alloc] initWithContentViewController:nav];
[_popover setPopoverContentSize:CGSizeMake(557, 700) animated:YES];
_popover.delegate = self;
[_popover presentPopoverFromBarButtonItem:self.navigationItem.rightBarButtonItem permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
}
Now implement NewItemDelegate method below this action method.
-(void)onTapDoneButton{
//dismiss popover here
}
I had this problem too and solved it using notifications.
In your parent controller, in viewDidLoad method, you have to add an observer:
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(closePopover)
name:#"closePopoverName"
object:nil];
Then, in your viewDidUnload method you remove the observer like this:
[[NSNotificationCenter defaultCenter] removeObserver:self];
Of course, you have to create the function which actually dismisses the popover:
- (void) closePopover
{
[_popover dismissPopoverAnimated:YES];
}
Then, in your ItemContent controller, you just post a notification when you want to close the popover:
[[NSNotificationCenter defaultCenter] postNotificationName:#"closePopoverName" object:self userInfo:nil];
You could define a protocol on ItemContent and use it on your CallerViewController. If you want to close your Popover, just call your delegate method, which you will implement on your CallerViewController
Really simple question i think.
i have a main view and a popover view.
i am trying to make a custom delegate which will enable me to close the popover view at certain times. My code is posted below. The real simple issue i am having is my code dosnt appear to be entering the delegate code. Any ideas as to why? It builds and runs but nothing appears to happen, i have put NSLog statments, the popover nslog appears but the function in
mainview dismissPopover does nothing.
Mainview.h
#interface MainScreen : UIViewController<DismissPopoverDelegate>
Mainview.m
- (void) dismissPopover:(NSNumber *)dataa
{ /* Dismiss you popover here and process data */
[popoverController dismissPopoverAnimated:YES];
NSLog(#"OLOLO");
}
Popover.h
#protocol DismissPopoverDelegate
- (void) dismissPopover:(NSNumber *)yourDataToTransfer;
#end
#interface SelectAgePopOver : UIViewController<UITableViewDataSource,
UITableViewDelegate,UIPopoverControllerDelegate>{
NSArray *items;
id<DismissPopoverDelegate> delegate;
}
#property (nonatomic, assign) id<DismissPopoverDelegate> delegate;
Popover.m
[self.delegate dismissPopover:selrow];
where i want the delegate called.
Thanks
the popover view is called by the following method in main view.m
controller = [[SelectAgePopOver alloc] initWithNibName:#"SelectAgePopOver" bundle:nil];
popoverController = [[UIPopoverController alloc] initWithContentViewController:controller];
[popoverController setDelegate:self];
popoverController.popoverContentSize = CGSizeMake(250, 294);
if ([popoverController isPopoverVisible]) {
[popoverController dismissPopoverAnimated:YES];
} else {
CGRect popRect = CGRectMake((self.AgeRangeTextField.frame.origin.x+50),
(self.AgeRangeTextField.frame.origin.y+50),
(self.AgeRangeTextField.frame.size.width),
(self.AgeRangeTextField.frame.size.height));
[popoverController presentPopoverFromRect:popRect inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
}
On where you instantiate the instance of the SelectAgePopOver, you need to set the delegate of the SelectAgePopOver instance to the MainScreen (self) in the Mainview.m, for example:
controller = [[SelectAgePopOver alloc] initWithNibName:#"SelectAgePopOver" bundle:nil];
;
controller.delegate = self;
Please try to set the controller delegate as shown above.
In the SelectAgePopOver.h class file, you do not need to set UIPopOverControllerDelegate though.
I have two views setup ( inside a TabBar). The DetailView with a button that calls a PopOver with a NavigationController+UITableView (RootView) loading data from CoreData. I have a problem passing data from the UITableView to the DetailView. I have a protocol declared in RootView and used in the DetailView.
Here is the code I use to create the PopOver from the button because I think I have some delegate issues. Any help will be amazing,
- (IBAction)zoneListButtonController
{
if (self.controladorPopOver == nil) {
ipadrootviewController = [[iPadRootViewController alloc] initWithNibName:#"iPadRootView" bundle:[NSBundle mainBundle]];
UINavigationController *ipadnavController = [[UINavigationController alloc]
initWithRootViewController:ipadrootviewController];
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:ipadnavController];
self.controladorPopOver = popover;
popover.delegate = self;
self.title = #"Countries";
popover.popoverContentSize = CGSizeMake(320, 300);
[self.controladorPopOver presentPopoverFromRect:CGRectMake(112, 20, 86, 27) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
[ipadnavController release];
[controladorPopOver release];
}
}
An instance of the SubZone1iPadController doesn't exist when you create the popover in DetailView so you can't set its delegate property directly from the DetailView.
One option is to also add the delegate property to the iPadRootViewController which you can set in the zoneListButtonController method. Then, when ipadrootviewController creates the SubZone1iPadController, pass along the delegate.
So in both ipadrootviewController and SubZone1iPadController, add a delegate property:
#property (nonatomic,assign) id <SubZone1Tap> delegate;
Then, in the zoneListButtonController method, set the delegate property on iPadRootViewController:
ipadrootviewController = [[iPadRootViewController alloc] init...
ipadrootviewController.delegate = self;
Then, where ipadrootviewController creates SubZone1iPadController:
SubZone1iPadController *sz1 = [[SubZone1iPadController alloc] init...
sz1.delegate = self.delegate;
[self.navigationController pushViewController:...
[sz1 release];
Finally, in the DetailView, make sure the delegate method is implemented. For example:
-(void)SubZone1Tap:(NSString *)name
{
NSLog(#"SubZone1Tap, name = %#", name);
//dismiss the popover if that's what you need to do...
[controladorPopOver dismissPopoverAnimated:YES];
}
I used a Popover to display image in it. When the user touch a button, the popover appears with a slideshow inside.
I initialize the Popover like this : `
- (IBAction)showPopover:(UIButton *)sender {
myPopover *content = [[myPopover alloc] init];
detailViewPopover = [[UIPopoverController alloc] initWithContentViewController:content];
detailViewPopover.popoverContentSize = CGSizeMake(600., 400.);
detailViewPopover.delegate = self;
[detailViewPopover presentPopoverFromRect:sender.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
[content release];
}
`
detailViewPopover is a UIPopoverController, I declare it my .h.
I dismiss the Popover like this : `
- (void)popoverControllerDidDismissPopover:(UIPopoverController *)popoverController {
// If a popover is dismissed, set the last button tapped to nil.
[popoverController release];
}`
When I run my app, it works until I got "-[UIPopoverController release]: message sent to deallocated instance 0x1b29b0" and my apps crashes...
I understand I release too much time my UIPopoverController, but I don't know where. Is my implementation good ?
Thanks for your help
Let me know if you need more information, I will edit the post
You shouldn't release your popoverController here.
You need to call release on detailViewPopover in your current view controllers dealloc method
- (void) dealloc
{
[detailViewPopover release];
[super dealloc];
}
