I have a root view controller in which I load a sub view that contains three buttons. When I touch one of them a popover is shown. The popover contains an image view and a bar with a Done button. I want to dismiss this popover when the Done button is touched. To accomplish this I am using this code
- (IBAction)btnDone:(UIBarButtonItem *)sender {
[self.view removeFromSuperview];
[APPDELEGATE.parkDetail. popoverController dismissPopoverAnimated:YES];
// [APPDELEGATE.parkDetail.popoverController dismissPopoverAnimated:YES ];
}
and the popover is presented like this
- (IBAction)btnParkMap:(id)sender {
[popoverController dismissPopoverAnimated:YES];
if ([popoverController isPopoverVisible]) {
[popoverController dismissPopoverAnimated:YES];
} else {
parkMap * v = [[parkMap alloc]initWithNibName:#"parkMap" bundle:nil];
v.contentSizeForViewInPopover = CGSizeMake(350, 300);
popoverController = [[UIPopoverController alloc] initWithContentViewController:v];
CGRect popRect = CGRectMake(self.btnShowPopover.frame.origin.x+330,
self.btnShowPopover.frame.origin.y+170,
self.btnShowPopover.frame.size.width,
self.btnShowPopover.frame.size.height);
[popoverController presentPopoverFromRect:popRect inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
}
}
Try this code
[self dismissViewControllerAnimated:YES completion:nil];
Or try #nirav's ans
Try to write below code
[yourPopOverobject dismissPopoverAnimated:YES];
Let me know whether it is working or not..
Happy Coding!!!!!
The PopUpOver can beswitch off the default contextual menu of UIWebView. This is easy because we only need to set the CSS property “-webkit-touch-callout” to “none” for the body element of the web page. We can do this using JavaScript in the UIWebView delegate method “webViewDidFinishLoad:”…
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
[webView stringByEvaluatingJavaScriptFromString:#"document.body.style.webkitTouchCallout='none';"];
}
- (IBAction)btnDone:(UIBarButtonItem *)sender {
[self dismissViewControllerAnimated:YES completion:nil];
}
Try to check below code...
if ([popoverobject isPopoverVisible]) {
[popoverobject dismissPopoverAnimated:YES];
[popoverobject release];
}
}
#pragma mark -
#pragma mark UIPopoverController delegate
-(void)popoverControllerDidDismissPopover:(UIPopoverController *)popoverController {
//if (popoverController == popoverobject) {
[popoverobject release];
// }
}
- (BOOL)popoverControllerShouldDismissPopover:(UIPopoverController *)popoverController {
NSLog(#\"popover about to be dismissed\");
return YES;
}
let me know is it working or not...

I am new to objective C.
I am trying to load new view from current view on button click but when i click on button it executes a code but does nothing i.e. does not load new view controller..
following is my code...
- (void)zxingController:(ZXingWidgetController*)controller didScanResult:(NSString *)resultString {
[self dismissModalViewControllerAnimated:YES];
//Display QRCode in string....
NSLog(#"Result::::%#",resultString);
[_qrCodeParser initWithQRString:resultString];
int i=[_qrCodeParser parseQROCode];
sharedInstance=[SharedInstance sharedInstance];
NSLog(#"%#",sharedInstance._medicineData);
if (i==0) {
_detailView= [[AlarmViewController alloc] initWithNibName:#"AlarmViewController" bundle:nil];
[self presentViewController:_detailView animated:YES completion:nil];
}
}
Tried with removing "dismissModalViewControllerAnimated" controller line like below:
- (void)zxingController:(ZXingWidgetController*)controller didScanResult:(NSString *)resultString {
//[self dismissModalViewControllerAnimated:YES];
//Display QRCode in string....
NSLog(#"Result::::%#",resultString);
[_qrCodeParser initWithQRString:resultString];
int i=[_qrCodeParser parseQROCode];
sharedInstance=[SharedInstance sharedInstance];
NSLog(#"%#",sharedInstance._medicineData);
if (i==0)
{
_detailView= [[AlarmViewController alloc] initWithNibName:#"AlarmViewController" bundle:nil];
[self presentViewController:_detailView animated:YES completion:nil];
}
}
Hope it will be helpful to you.
Cheers!
When I try to dismiss my UIImagePickerController, it crashes the app. the error is: "Terminating app due to uncaught exception 'UIApplicationInvalidInterfaceOrientation', reason: 'preferredInterfaceOrientationForPresentation must return a supported interface orientation!'"
I have the preferred interface orientation set in my view controller.
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return UIInterfaceOrientationIsPortrait(interfaceOrientation);
}
- (BOOL) shouldAutorotate {
return YES;
}
Here is the method I'm calling to bring up the camera, this works fine for adding the camera, but like I said, crashes when I try to remove the camera.
-(IBAction)addCamera:(id)sender
{
self.cameraController = [[UIImagePickerController alloc] init];
self.cameraController.sourceType = UIImagePickerControllerSourceTypeCamera;
self.cameraController.cameraViewTransform = CGAffineTransformScale(self.cameraController.cameraViewTransform,
1.13f,
1.13f);
self.cameraController.showsCameraControls = NO;
self.cameraController.navigationBarHidden = YES;
self.wantsFullScreenLayout = YES;
ar_overlayView = [[UIView alloc] initWithFrame:CGRectZero];
self.view = ar_overlayView;
[self.cameraController setCameraOverlayView:ar_overlayView];
[self presentViewController:cameraController animated:NO completion:nil];
[ar_overlayView setFrame:self.cameraController.view.bounds];
}
-(IBAction)back:(id)sender
{
[ar_overlayView removeFromSuperview];
[cameraController dismissViewControllerAnimated:NO completion:nil];
}
Alright, found the solution, it was really simple, I just changed my back method to:
[self dismissModalViewControllerAnimated:YES];
Now my camera goes away and I can see my original view when I press the back button.
I still haven't figured out what was causing the original problem as I've gone through the info.plist and the methods for supported orientations, but this accomplishes what I wanted.
I'm still curious as to what was causing the error though if anyone has any ideas.
You can try remove this method:
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
It will fix it.but sometimes it will lead to reduce stateBar height.
You cannot remove a UIViewController's main view from its superview.
Instead of this:
self.view = ar_overlayView;
Try this:
[self.view addSubview:ar_overlayView];
Then you will be able to remove it from the superview correctly.
You should be using the didFinishPickingMedieWithInfo method similar to below and use [self dismissModalViewControllerAnimated:YES];
-(void) imagePickerController:(UIImagePickerController *) picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
if (picker.sourceType == UIImagePickerControllerSourceTypeCamera) {
NSLog(#"Camera");
}
else {
NSLog(#"Album");
}
[self dismissModalViewControllerAnimated:YES];
}
I don't think you need to add ar_overlayView to the current view yourself if it's a camera overlay.
Here's what your code is doing now:
Add ar_overlayView to the current view
Add ar_overlayView as the camera's overlay view
Show the camera view (modal)
At this point, ar_overlayView is being displayed twice. When you send it the removeFromSuperview message on dismissing the camera view, it might be getting confused since it's in two view hierarchies at the same time.
Skipping the self.view = ar_overlayView; or [self.view addSubview:ar_overlayView]; lines should fix the problem.
Also, dismissViewControllerAnimated:completion: should be sent to the same object that presentViewController:animated:completion was called on (self in this case):
-(IBAction)addCamera:(id)sender
{
// -- snip -- //
ar_overlayView = [[UIView alloc] initWithFrame:self.cameraController.view.bounds];
[self.cameraController setCameraOverlayView:ar_overlayView];
[self presentViewController:self.cameraController animated:NO completion:nil];
}
-(IBAction)back:(id)sender
{
[self dismissViewControllerAnimated:NO completion:nil];
}
So I have a UITabBarController app and I want to display a login page, and so I did:
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(userDidLogin:) name:UserDidLoginNotification object:nil];
LoginViewController* loginViewController = [[LoginViewController alloc] init];
self.tabBarController.selectedViewController = [self.tabBarController.viewControllers objectAtIndex:0];
[self.tabBarController.selectedViewController presentModalViewController:loginViewController animated:NO];
[loginViewController release];
Inside my LoginViewController I can as well show another modalViewController:
- (void) twitterLogin: (UIViewController *) askingView
{
UIViewController *controller = [SA_OAuthTwitterController controllerToEnterCredentialsWithTwitterEngine: _twitter delegate: self];
if (controller) {
self.askingView = askingView;
[askingView presentModalViewController: controller animated: YES];
}
}
I have the following method where the askingView is the LoginViewController,
when I want to dismiss this I do:
[self.askingView dismissModalViewControllerAnimated:YES];
[[NSNotificationCenter defaultCenter] postNotificationName:UserDidLoginNotification object:nil];
However, this doesn't dismiss the LoginViewController and show the UITabBarController views.. it just dismisses my modalViewController shown from the LoginvVIewController. What am I doing wrong here? I am also getting the following error:
attempt to dismiss modal view controller whose view does not currently appear. self = <LoginViewController: 0x2aff70> modalViewController = <SA_OAuthTwitterController: 0x2d2a80>
2011-09-16 09:45:37.750 VoteBooth[4614:707] attempt to dismiss modal view controller whose view does not currently appear. self = <MainViewController: 0x29fec0> modalViewController = <LoginViewController: 0x2aff70>
In order to dismiss a modal view that is presented over another modal view, you have to call dismissModalViewControllerAnimated: on the parent of the parent. I have used this in some of my apps and it has worked beautifully for me (after many painstaking hours trying to figure it out). Here is exactly what I've used:
[[[self parentViewController] parentViewController] dismissModalViewControllerAnimated:YES];
if ([self respondsToSelector:#selector(presentingViewController)]) {
[self.presentingViewController.presentingViewController dismissModalViewControllerAnimated:YES]; // for IOS 5+
} else {
[self.parentViewController.parentViewController dismissModalViewControllerAnimated:YES]; // for pre IOS 5
}
If you have a dynamic UX and do not know how many parents to go to, you can use this recursive function to figure it out...
- (void) goHome
{
//Dismiss modal back to home page
int numberOfVcsToDismiss = [self findRootViewController:self];
[self dismissToRootVc:numberOfVcsToDismiss];
}
- (int) findRootViewController:(UIViewController*)vc
{
if(vc)
{
return 1 + [self findRootViewController:vc.presentingViewController];
}
return 0;
}
- (void) dismissToRootVc:(int)count
{
if(count == 1)
[self dismissViewControllerAnimated:YES completion:^{}];
if(count == 2)
[self.presentingViewController dismissViewControllerAnimated:YES completion:^{}];
if(count == 3)
[self.presentingViewController.presentingViewController dismissViewControllerAnimated:YES completion:^{}];
if(count == 4)
[self.presentingViewController.presentingViewController.presentingViewController dismissViewControllerAnimated:YES completion:^{}];
if(count == 5)
[self.presentingViewController.presentingViewController.presentingViewController.presentingViewController dismissViewControllerAnimated:YES completion:^{}];
//etc....
}
i have added a UIPopover to my navigationbar when the user touches the rightbarbuttonitem.
I want to know whats the cleanest coding for showing and dismissing the popover. With the code below, it works, but not correct.
If the user touches the rightbarbuttonitem first, the popover appears. Now he can choose a cell,.. works. Or you can touch outside the popover and it disappears. Both ways correctly.
But when touching the rightbarbuttonitem and after that, the same touch on that icon again, you have to touch it twice to bring up that popover again. (Not on the first touch).
How should that correctfunction look like? Thanks for your time..

Comments
Your downloads: method checks for tableViewController value and make decision if UIPopoverController should be displayed or dismissed. But yours selectedTable: method does dismiss popoverController and does not set tableViewController to nil thus it doesn't work as expected by you.
And I also don't see UIPopoverControllerDelegate implementation, especially popoverControllerDidDismissPopover: which will tell you when UIPopoverController was dismissed (by touching outside your UIPopoverController for example).
Memory Management
Read memory management guide. [self.popoverController release] with self.popoverController = nil leads to crash - one release and second release during setting to nil. (I assume your popoverController property retains).
#Chiefly Izzy: Thanks for your help. You point me in the right direction.
Here´s the code i´m using. It works great. Hope that memory management is clean, too. Isn´t it?

I have a MKMapView (also a UIPopoverControllerDelegate) with Annotations. This MapView has, in the MKTestMapView.h file, a UIPopoverController* popoverController defined in the #interface and a #property (nonatomic, retain) UIPopoverController* popoverController; defined outside of the #interface section. This controller is #synthesized in the MKTestMapView.m file and it is released in the - (void)dealloc section. The Annotations in this MapView have rightCalloutAccessoryViews defined to the following:
- (void)mapView:(MKMapView *)mapView2 annotationView:(MKAnnotationView *)aview calloutAccessoryControlTapped:(UIControl *)control{
...
CGPoint leftTopPoint = [mapView2 convertCoordinate:aview.annotation.coordinate toPointToView:mapView2];
int boxDY=leftTopPoint.y;
int boxDX=leftTopPoint.x;
NSLog(#"\nDX:%d,DY:%d\n",boxDX,boxDY);
popoverController = [[UIPopoverController alloc] initWithContentViewController:controller];
popoverController.delegate = self;
CGSize maximumLabelSize = CGSizeMake(320.0f,600.0f);
popoverController.popoverContentSize = maximumLabelSize;
CGRect rect = CGRectMake(boxDX, boxDY, 320.0f, 600.0f);
[popoverController presentPopoverFromRect:rect inView:self.view permittedArrowDirections:UIPopoverArrowDirectionRight animated:YES];
...
}
Now here comes the fun part. First of all, I am not sure if I need maximumLabelSize and the rect to be the same size. I am new to the popovercontroller so I am playing this by ear..
Okay, the popover shows. Now to dismissing it. I can click anywhere on mapView2 and the popover goes away...but I need the user to click a button in the view if they change anything. URGH!
The docs show:
To dismiss a popover programmatically,
call the dismissPopoverAnimated:
method of the popover controller.
Well, here is the problem: By definition of how the popoverController works, you are clicking inside the view of the displayed popover (to click the button) but have to trigger the dismissPopoverAnimated: method of the controller that launched this popover view, in my case, the popoverController inside the MKTestMapView.m file.
Now, having said all that, remember, [popoverController release] doesn't happen until:
- (void)dealloc {
[popoverController release];
[mapView release];
[super dealloc];
}
So, do i just do the following inside the button (messy but may work):
(Assuming my popover view is a TableView) In the:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
MKTestMapView * mKTestMapView = [[MKTestMapView alloc] init];
[[mKTestMapView popoverController].dismissPopoverAnimated:YES];
}
Here is my issue: I cannot figure out whether doing the above gives me a reference (if there is such a thing) to the existing view that is on the screen -- and therefore the view that is the owner of that popoverController. If it is as simple as
[[[self parentView] popoverController].dismissPopoverAnimated:YES];
I will shoot myself cos I don't think that is the correct syntax either!
This should be easy...yet I am lost. (probably just frustrated with so many iPad differences that I am learning).
Can anyone explain more?
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 :)
Here is another simple solution.
I found that we should follow the following steps for clearly dismissing popovers.
dismiss a popover.
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;
