Have anyone noticed that if you use UIImagePickerController and allowsEditing = YES in iOS 8, your app will crash after the editing view being presented.
*** -[PUUIImageViewController traitCollection]: message sent to deallocated instance 0x7f8d714ab5e0
I can find few information about this PUUIImageViewController. It seems like a new class in iOS 8.
I've spent 2 days on my code and started thinking this may be a bug in iOS 8.
Any ideas?
Here's my code for opening the UIImagePickerController
- (void)picButtonPressed:(id)sender {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
self.imagePickerController = [[UIImagePickerController alloc] init];
self.imagePickerController.delegate = self;
self.imagePickerController.allowsEditing = YES;
self.imagePickerController.mediaTypes = #[(NSString *)kUTTypeImage];
self.imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:self.imagePickerController animated:YES completion:^{
}];
}
}
As for UIImagePickerController's delegate:
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[self dismissViewControllerAnimated:YES completion:^{}];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *image = info[UIImagePickerControllerEditedImage];
[self dismissViewControllerAnimated:YES completion:^{}];
}
The app crashes after the controller dismiss UIImagePickerController.

I have a problem where the delegate of UIImagePickerController not being called when presented with sourceType = UIImagePickerControllerSourceTypePhotoLibrary.
Oddly enough, it works perfectly fine in camera mode.
Interface declaration:
#interface ChatVC : UIViewController <UIActionSheetDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate>
And in implementation:
- (void)takePhotoAction {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
UIImagePickerController* imgPickerController = [[UIImagePickerController alloc] init];
imgPickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
imgPickerController.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
imgPickerController.allowsEditing = YES;
imgPickerController.delegate = self;
[self presentViewController:imgPickerController animated:YES completion:nil];
}
}
- (void)choosePhotoFromLibraryAction {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
UIImagePickerController* imgPickerController = [[UIImagePickerController alloc] init];
imgPickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imgPickerController.allowsEditing = YES;
imgPickerController.delegate = self;
[self presentViewController:imgPickerController animated:YES completion:nil];
}
}
And here's the delegate method implementation in the same view controller:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary<NSString *,id> *)editingInfo {
NSLog(#"Image Picker Controller Picked Image - Deprecated");
[picker dismissViewControllerAnimated:YES completion:nil];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSLog(#"Image Picker Controller Picked Image");
[picker dismissViewControllerAnimated:YES completion:nil];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
NSLog(#"Image Picker Controller Cancelled");
[picker dismissViewControllerAnimated:YES completion:nil];
}
When opened in camera mode, everything works just fine, and I can see the appropriate delegate methods being called.
But when opened in photo library mode and I choose a photo, nothing happens and no delegate method is called. However, I can see -imagePickerControllerDidCancel: delegate method being called when I tap on Cancel button.
I even suspected memory warning somehow invalidates the delegate, but it was not the case here.
Please someone help me figure this out.
Thanks in advance!
I'm using ios 8.4. When debugging an app, and I present a UIImagePickerController, xcode loses connection with the iphone. This wasn't a problem before.
Sometimes it will bring up the image picker... but then when I save an image, there'll be a crash.
Is anyone else experiencing this? How to fix?
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePickerController.editing = NO;
imagePickerController.delegate = self;
imagePickerController.showsCameraControls=YES;
[self presentViewController:imagePickerController animated:YES completion:nil];
try this code
- (IBAction)galleryButtonPressed:(id)sender
{
UIImagePickerController *pickerController = [[UIImagePickerController alloc] init];
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
pickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
pickerController.allowsEditing = YES;
pickerController.delegate = self;
[self presentViewController:pickerController animated:YES completion:NULL];
}
}
#pragma mark - UIImagePickerControllerDelegate
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[self dismissViewControllerAnimated:YES completion:NULL];
UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage];
if (image == nil)
image = [info objectForKey:UIImagePickerControllerOriginalImage];
// Do something with the image
[self.imageView setImage:image];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[self dismissViewControllerAnimated:NO completion:nil];
}
I am trying to select a picture from the device's photo library.
This is my code so far. I am following a tutorial and that should work, but I am getting an error :
"Use of undeclared identifier info", on the second method, line 3.
What am I doing wrong?
- (IBAction)selectPicturePressed:(UIButton *)sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = NO;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker animated:YES completion:NULL];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)img editingInfo:(NSDictionary *)editInfo
{
UIImage *chosenImage = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
self.imgToUpload.image = chosenImage;
[picker dismissViewControllerAnimated:YES completion:NULL];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:NULL];
}
Change info to editInfo will resolve it.
I have a problem with iOS ImagePicker. It works correctly, but when I want to take another photo the camera loads for a very long time (first time: 1-2sec, second time and later: 8-10sec). This is how I use it:
- (void)takePhoto {
_imagePicker = [UIImagePickerController new];
_imagePicker.delegate = self;
_imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
_imagePicker.allowsEditing = NO;
[self presentViewController:_imagePicker animated:YES completion:nil];
}
and this is how I get the image:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo {
[_imagePickerView.imageView setImage:image];
}
I don't see there much place for bugs. Of course I implement protocols UIImagePickerControllerDelegate and UINavigationControllerDelegate.
Do you have any ideas how can I figure out what is causing this?
You may want to dismiss the UIImagePickerController after you picked an item by calling
[_imagePicker dismissViewControllerAnimated:YES completion:nil];
It should be fine, now.
Try changing your first block of code to reuse the same imagePicker you have already initialized:
- (void)takePhoto {
if(_imagePicker == nil)
_imagePicker = [UIImagePickerController new];
_imagePicker.delegate = self;
_imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
_imagePicker.allowsEditing = NO;
[self presentViewController:_imagePicker animated:YES completion:nil];
}
I have a UIPickerController that gets your pictures and allows you to pick some of them though at the moment when I click the button to activate it the app crashes.
Here is the code that I am using for it:
in my ViewDidLoad method:
pickerController = [[UIImagePickerController alloc] init];
pickerController.allowsEditing = NO;
pickerController.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
The function:
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[self dismissViewControllerAnimated:YES completion:nil];
patientPicture = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
UIImageView *pictureView = (UIImageView *)[imageCell viewWithTag:777];
pictureView.image = patientPicture;
[_imgViewAdd reloadInputViews];
}
And it being called:
- (IBAction)addPicture:(id)sender {
[self presentViewController:pickerController animated:YES completion:nil];
}
It is wierd because I have recently changed my app to Ipad only though while it was in IPhone it worked fine. When you click the button in NSLog this error message crops up which I supose is something to do with it:
UIStatusBarStyleBlackTranslucent is not available on this device.
I suspect this is quite a common issue that people have
Thanks in advance
Try presenting in a popover...
pickerController = [[UIImagePickerController alloc] init];
UIPopoverController *popOverController = [[UIPopoverController alloc] initWithContentViewController:pickerController];
popOverController.delegate = self;
and to present...
[popOverController presentPopoverFromRect:yourframe inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
