I'm calling [picker dismissViewControllerAnimated:YES completion:NULL]; when user either chooses a picture from the library or cancels.
I'm also setting delegate to nil just to be sure but that doesn't help either.
Am I missing something?
-(void)callImagePickerDelegate:(CameraView *)sender{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
[self presentViewController:picker animated:YES completion:NULL];
self.imageFromLibrary.frame = CGRectMake(0, self.imageFromLibrary.frame.origin.y, self.imageFromLibrary.frame.size.width, self.imageFromLibrary.frame.size.width);}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:NULL];
[self.cameraView.session startRunning];
picker.delegate = nil;}
I think you have declared your picker as strong property that is why it is not releasing it's memory.
Declare your picker as weak property and then try .
Hope it helps.
You nil only delegate of picker not actual picker object. so set picker = nil, if you have't used ARC then also write picker = nil;[picker release];

I pushed modally to a new view controller using:
[self presentViewController:picker];
and then from within that new view controller I did;
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.delegate = self;
[self presentViewController:picker animated:YES completion:nil];
But the camera won't even show, why?
I had the same problem on iPad and below code worked for me...
[[NSOperationQueue mainQueue] addOperationWithBlock:^{
//present your view controller here...
}];
Good Luck !! :)
This might be due to couple of reasons:
1) Create a method of Camera Opening code:
-(void) openCamera {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.delegate = self;
[self presentViewController:picker animated:YES completion:nil]; }
And call it like this Wherever you want,
[self performSelector:#selector(openCamera) withObject:nil afterDelay:0.1];
OR
2) Write code inside this method,
[[NSOperationQueue mainQueue] addOperationWithBlock:^{
//... Camera Code ....
}];
On iOS 7 only, the navigation bar in my app does not respond to any touches after a UIImagePickerController is used and then dismissed (whether a pic has been selected or not). The screen below the navigation bar functions as normal, but it is now impossible to navigate Back in the app; the user is stuck on this screen.
I am launching the UIImagePickerController from code, though the rest of the app is laid out in storyboards.
UIImagePickerController *mediaUI = [[UIImagePickerController alloc] init];
mediaUI.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
mediaUI.mediaTypes = [NSArray arrayWithObject:(NSString *) kUTTypeImage];
mediaUI.allowsEditing = NO;
mediaUI.delegate = self;
[controller presentModalViewController: mediaUI animated: YES];
Thanks in advance for any help.
I hope you are performing these steps correctly!
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[picker dismissViewControllerAnimated:YES completion:NULL];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:NULL];
}
And when you are calling
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:NULL];
Cheers!
I noticed that the log was showing "Unbalanced calls to begin/end appearance transitions for" the launching controller. I was launching the image picker controller immediately from another controller when it appeared. This works OK on iOS 8 but there needs to be a delay on iOS 7. I fixed it by calling my method after a brief delay:
[self performSelector:#selector(takePicture) withObject:nil afterDelay:.1];
I want to launch camera when my view controller loads. I tried calling takePhoto method in viewdidload but nothing happens, what did I do wrong? I am getting the following error msg:
"Attempt to present on whose view is not in the window hierarchy!"
When I inspect element UIImagePickerController, it is nil... Interestingly, I can place a button that calls this method and when I tap the button it works fine, but not when I call it in view did load...
- (IBAction)takePhoto {
UIImagePickerController *uiipc=[[UIImagePickerController alloc]init];
uiipc.delegate=self;
uiipc.mediaTypes=#[(NSString *)kUTTypeImage];
uiipc.sourceType=UIImagePickerControllerSourceTypeCamera|UIImagePickerControllerSourceTypePhotoLibrary;
uiipc.allowsEditing=YES;
[self presentViewController:uiipc animated:YES completion:NULL];
}
Try this: Call the camera from the view did appear method:
// makeCameraOff= YES; call this in didFinishPickingMediaWithInfo method
-(void)viewDidAppear:(BOOL)animated{
if (makeCameraOff==NO){
[self performSelector:#selector(takePic) withObject:nil afterDelay:0];
}
}
-(void)takePic{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate =self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:nil];
}
I have an app which has a toolbar at the bottom with one of the options as Upload. On clicking on it, a PopOverController occurs which displays the list of photos to choose from.
After choosing a photo, I want to display a view (inside the PopOverController itself)which contains the photo alongwith the button called as Upload. On choosing my photo, currently my PopOverController is not getting dismissed. I have used the following lines of code :
-(IBAction)photolibrarypressed:(id)sender{
NSLog(#"hi");
UIImagePickerController *picker= [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
picker.delegate = self;
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:picker];
self.popoverController = popover;
popoverController.delegate = self;
[popoverController presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
imageView = [[UIImageView alloc] initWithFrame:[window bounds]];
[window addSubview:imageView];
imageView.hidden = YES;
[window makeKeyAndVisible];
}
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingImage:(UIImage *)image
editingInfo:(NSDictionary *)editingInfo
{
imageView.image = image;
NSLog(#"hellow");
[self dismissModalViewControllerAnimated:YES];
// need to show the upload image button now
upload.hidden = NO;
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[picker dismissModalViewControllerAnimated:YES];
exit(0);
}
Can Someone help me to sort out the issue ??
Instead of calling
[self dismissModalViewControllerAnimated:YES];
call the same cancel method as int eh cancel method to handle dismissing it's modal view
[picker dismissModalViewControllerAnimated:YES]; // Dismisses modalView
Hi In my app I have a button so when you click it a UIPopover comes up with an add contact view in it. It all workers except when you press save. It doesn't Dismiss.
-(IBAction) addcontact
{
ABNewPersonViewController *contacts = [[ABNewPersonViewController alloc] init];
// imagePicker.delegate = self;
// UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:contacts];
UINavigationController *addContactNavController = [[UINavigationController alloc] initWithRootViewController:contacts];
popover = [[UIPopoverController alloc] initWithContentViewController:addContactNavController];
popover.popoverContentSize = CGSizeMake(320, 1000);
[popover presentPopoverFromRect:CGRectMake(935, 270, 175, 300)
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionRight
animated:YES];
[popover retain];
[addContactNavController release];
[contacts release];
}
Implement the ABNewPersonViewControllerDelegate protocol and assign the delegate in your method above –
contacts.newPersonViewDelegate = self;
You can then dismiss the popover in the delegate function –
- (void)newPersonViewController:(ABNewPersonViewController *)newPersonView
didCompleteWithNewPerson:(ABRecordRef)person {
[popOver dismissPopoverAnimated:YES];
}
- (void)popoverControllerDidDismissPopover:(UIPopoverController *)popoverController {
[popOver release];
}
well,
[self dismissModalViewControllerAnimated:YES];
respecively
[popover dismissPopoverAnimated:YES];
should do it?
Edit: to be more concrete:
....
popover = [[UIPopoverController alloc] initWithContentViewController:addContactNavController];
addContactNavController.delegate = self;
now on saving, do something like:
-(IBAction) saveStuff {
... saving...
[delegate closePopup];
}
and in your File with -(IBAction) addcontact you do:
-(void) closePopup {
[self dismissModalViewCotroller...];
}
makes sense?
and yes, you should add a delegate-propery to your controller if not done yet
