I have the UIImagePickerController as a content View Controller for the UIPopoverController. I need to detect when the popover has just finished presented (has just showed up). UIPopoverController does not have any delegate for this. I can't seem to find a way to detect the UIImagePickerController as well. (This is for iPad)
Any suggestions?
// UIImagePickerController let's the user choose an image.
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
self.popover = [[UIPopoverController alloc] initWithContentViewController:imagePicker];
self.popover.delegate = self;
[self.popover presentPopoverFromBarButtonItem:self.openPhotosButton permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
The UIImagePickerDelegate is also a UINavigationControllerDelegate.
Your class should implement UINavigationControllerDelegate and include the following:
-(void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
// [navigationController setNavigationBarHidden:YES];
[[UIApplication sharedApplication] setStatusBarHidden:YES]; // This one works for me: OP
}
I've tested this and it hides the navigation bar. I am not sure if doing so conflicts with the HIG though.
Thise should help:
UIImagePickerControllerDelegate and imagePickerController:didFinishPickingMediaWithInfo:
UIPopoverControllerDelegate popoverControllerDidDismissPopover
You have delegates for both

I am using AddressBookUI Framework for Adding contact, when I tried to pushing this view controller then cancel and done button not working properly, I don't want to present it
Here is my code
ABNewPersonViewController *abnpvc = [[ABNewPersonViewController alloc] init];
[abnpvc setNewPersonViewDelegate: self];
[self.navigationController pushViewController:abnpvc animated:YES];
I am also tried add as subview rather then pushing it but when I am adding as subview then it was not added
As per comment i have tried like
UINavigationController *navigation = [[UINavigationController alloc] initWithRootViewController:abnpvc];
[self presentViewController:navigation animated:YES completion:nil];
Can anyone help me out why properly not working ?
You can implement that too considering also the other answers and the deprecations to ABNewPersonViewController in iOS 9.
As per your remarks:
cancel and done button not working properly
They are working if you have included the ABNewPersonViewControllerDelegate on interface like this:
#interface ViewController () <ABNewPersonViewControllerDelegate>
Pushing the viewController on navigation stack like this:
ABNewPersonViewController *controller = [[ABNewPersonViewController alloc] init];
controller.newPersonViewDelegate = self;
[self.navigationController pushViewController:controller animated:YES];
And by conforming to the protocol by implementing this method:
- (void)newPersonViewController:(ABNewPersonViewController *)newPersonView didCompleteWithNewPerson:(nullable ABRecordRef)person {
// Trick to go back to your view by popping it from the navigation stack when done or cancel button is pressed
[self.navigationController popViewControllerAnimated:YES];
}
The tricky line is to pop the newPersonController from the navigation stack when either Done or Cancel button are pressed.
Enjoy it
Why can't you just do it as the docs say?
It is recommended that you present a new-person view controller modally.
Use
ABNewPersonViewController *abnpvc = [[ABNewPersonViewController alloc] init];
[abnpvc setNewPersonViewDelegate: self];
[self presentViewController:abnpvc animated:YES completion:nil];
That should work fine.
Edit
On second thought, did you set your delegate correctly and do the implementations get called? I suspect they are not implemented or the delegate is not set correctly.
Apple guideline(IMPORTANT) :: New-person view controllers must be used with a navigation controller in order to function properly. It is recommended that you present a new-person view controller modally.
Add Delegate
#interface ViewController () <ABNewPersonViewControllerDelegate>
Pushing the viewController
ABNewPersonViewController *abnpvc = [[ABNewPersonViewController alloc] init];
[abnpvc setNewPersonViewDelegate: self];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:abnpvc];
[self presentModalViewController:navController animated:YES];
And Now Add Delegate Method
#pragma mark ABNewPersonViewControllerDelegate methods
- (void)newPersonViewController:(ABNewPersonViewController *)newPersonViewController didCompleteWithNewPerson:(ABRecordRef)person
{
[self dismissViewControllerAnimated:YES completion:NULL];
}
That will work fine.
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:
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.
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've a view with UIImagePickerController..
In the whole application I have:
/* white color */
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
But in this case I need to view status bar black, so I set it:
/* black color */
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault];
I've do this in delegate
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated;
But seems ignoring instruction.
Works only for iOS < 8. I've already read this question and other, but I can't make it work.
Just change it from your xib / storyboad if you want to change for particular view means.
Try like this while presenting UIImagePickerViewController:
[self presentViewController:imagePickerController animated:YES completion:^{
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault];
}];
I resolved my problem in this way:
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
if(IS_IOS8_AND_UP) {
imagePickerController.modalPresentationStyle = UIModalPresentationFullScreen;
} else {
imagePickerController.modalPresentationStyle = UIModalPresentationCurrentContext;
}
imagePickerController.delegate = self;
[self presentViewController:imagePickerController animated:YES completion:nil];
And then in delegate I set the default status bar style.
Hope this help!
In iOS 6, I was using the following code to push a UIImagePickerController, of source type UIImagePickerControllerSourceTypeCamera, and to show its navigation bar. I wanted to show the navigation bar because after taking the image, I'm pushing another VC that allows the user to set some attributes in the database.
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
cameraController = [[UIImagePickerController alloc] init];
cameraController.delegate = self;
cameraController.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:cameraController animated:YES completion:NULL];
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault animated:YES];
[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationSlide];
cameraController.topViewController.title = #"Add";
cameraController.navigationBar.translucent = NO;
cameraController.navigationBar.barStyle = UIBarStyleDefault;
[cameraController setNavigationBarHidden:NO animated:NO];
}
In iOS 7 this code no longer shows the navigation bar. Does anyone know if there's a way to to get the navigation bar back for UIImagePickerController, of source type UIImagePickerControllerSourceTypeCamera?
Guess what? When imagePicker presents, it's automatic set to hidden....
All you need to do is setHidden:NO in next runloop. Like:
[self presentModalViewController:imagePicker animated:YES];
[self performSelector:#selector(showNavigationBar:) withObject:imagePicker afterDelay:0];
- (void)showNavigationBar:(UIImagePickerController*)imagePicker {
[imagePicker setNavigationBarHidden:NO];
}
#LeverkusenFan's solution works well. But instead of using a hack such as a run loop, you use the completion handler of presentViewController to achieve that effect.
[self presentViewController:cameraController animated:YES completion:^{
[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];
cameraController.topViewController.title = #"Add";
cameraController.navigationBar.translucent = NO;
cameraController.navigationBar.barStyle = UIBarStyleDefault;
[cameraController setNavigationBarHidden:NO animated:NO];
}];
In fact a better solution that avoids the weird animation when the navigation bar shows up and which works well when you press the back button on the nav bar is as follows:
In the delegate for the UIImagePickerController implement the following function.
- (void) navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
if (navigationController == self.cameraController && navigationController.viewControllers.count == 1) {
// When showing the ImagePicker update the status bar and nav bar properties.
[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];
navigationController.topViewController.title = self.cameraTitle;
navigationController.navigationBar.translucent = NO;
navigationController.navigationBar.barStyle = UIBarStyleDefault;
[navigationController setNavigationBarHidden:NO animated:animated];
}
}
This function will get called when the ImagePicker is shown and we only make the changes for the rootViewController of the ImagePicker (i.e. the camera screen).
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
