image picker not dismissing when picture tapped - iphone

Question

when the bar button item is tapped the popover view shows fine but it does not dismiss when a photo is selected. Am I missing something? What should i do?
-(IBAction)addPhoto:(UIBarButtonItem *)sender
{
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
popover = [[UIPopoverController alloc] initWithContentViewController:imagePicker];
[popover presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)selectedImage editingInfo:(NSDictionary *)editingInfo
{
// Delete any existing image.
NSManagedObject *oldImage = imageClass.image;
if (oldImage != nil)
{
[imageClass.managedObjectContext deleteObject:oldImage];
}
// Create an image object for the new image.
NSManagedObject *myImage = [NSEntityDescription insertNewObjectForEntityForName:#"Image" inManagedObjectContext:imageClass.managedObjectContext];
imageClass.image = myImage;
// Set the image for the image managed object.
[image setValue:selectedImage forKey:#"image"];
[popover dismissPopoverAnimated:YES];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[[picker parentViewController] dismissViewControllerAnimated:YES completion:nil];
}

Answer 1

The issue is that you are trying to dismiss the image picker controller but you need to dismiss the popover that it is in. Things need to be dismissed based on how they were presented.
Change:
[self dismissViewControllerAnimated:YES completion:nil];
to:
[popover dismissPopoverAnimated:YES];
Calling dismissViewControllerAnimated:completion: would be used if you have called presentViewController:animated:completion:.

Answer 2

To dismiss UIPopoverViewController on the selection of a photo from gallery, you need to add following lines in didFinishPickingMediaWithInfo method after picking an image.
- (void)imagePickerController:(UIImagePickerController *)imagePicker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[popover dismissPopoverAnimated:YES];
[imagePicker dismissModalViewControllerAnimated:YES];
}

Answer 3

You've not set delegate of imagePicker to self. Plus you need to take popover as instance variable to dismiss in delegate method.

Answer 4

1) in you .h you must add <UIImagePickerControllerDelegate>
2) add imagePicker.delegate=self; so your addPhoto method should look as below:
-(IBAction)addPhoto:(UIBarButtonItem *)sender {
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate=self; //add this line to your code
popover = [[UIPopoverController alloc]
initWithContentViewController:imagePicker];
[popover presentPopoverFromBarButtonItem:sender
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
}

Answer 5

just give the delegate UIPopoverControllerDelegate and UIImagePickerControllerDelegate in .h file

Answer 6

you must add UIImagePickerControllerDelegate to your corresponding .h file and also Check this Code
-(IBAction)addPhoto:(UIBarButtonItem *)sender
{
UIImagePickerController *imagePicker3 = [[UIImagePickerController alloc] init];
imagePicker3.delegate = self;
imagePicker3.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker3.allowsEditing = YES;
imagePicker3.mediaTypes = [NSArray arrayWithObject:#"public.image"]
[self presentModalViewController:imagePicker3 animated:YES];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[self dismissModalViewControllerAnimated:YES];
_imageselected.image=[info valueForKey:UIImagePickerControllerEditedImage];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[self dismissModalViewControllerAnimated:YES];
}

Answer 7

In case someone is still experiencing this infamous error when using UIImagePickerController:
Assigning to 'id <UINavigationControllerDelegate,UIImagePickerControllerDelegate>' from incompatible type 'DetailViewController *const __strong'
try to move
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
to the
- (void)viewDidLoad{
//do your stuff
}
and don't forget to include the delegate protocol definitions (<UINavigationControllerDelegate,UIImagePickerControllerDelegate>) in the corresponding .h file.
This solved my problem, hope it's gonna help someone else. Don't know if its the best solution, but worked for me in a similar case.
