Answer 1

The answer is in your error message.

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'On iPad, UIImagePickerController must be presented via UIPopoverController'

On an iPad, you can't just use the iPhone method of selecting an image. You need to use a UIPopoverController, you can pass it your UIImagePickerController with:

UIPopoverController* popover = [[UIPopoverController alloc] initWithContentViewController: imagePicker];

Then implement the UIPopoverControllerDelegate protocol in your class.

You can find an example of this here.

Answer 2

for Swift 4

get image from camera

let picker = UIImagePickerController()
picker.delegate = self
picker.allowsEditing = true
picker.sourceType = .camera
self.present(picker, animated: true, completion: nil)

get image from library

let picker = UIImagePickerController()
picker.delegate = self
picker.allowsEditing = true
picker.sourceType = .photoLibrary
self.present(picker, animated: true, completion: nil)

delegate function

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
  var result = false

  if let image = info[UIImagePickerControllerEditedImage] as? UIImage {
      //do something to image here ...

      picker.dismiss(animated: true, completion: nil)
  }
}

In your view controller, don't forget to inherit class UIImagePickerControllerDelegate, UINavigationControllerDelegate

- (void)buttonTap {

    UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle: nil
                                                         delegate: self
                                                cancelButtonTitle: @"Cancel"
                                           destructiveButtonTitle: nil
                                                otherButtonTitles: @"Take a new photo",
                                                         @"Choose from existing", nil];
                                                   [actionSheet showInView:self.view];
}

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {

    int i = buttonIndex;

        switch(i) {

    case 0:
    {

      //Code for camera  

    }
        break;
    case 1:
    {
        UIImagePickerController * picker = [[UIImagePickerController alloc] init];
        picker.delegate = self;
        picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
       self.popover = [[UIPopoverController alloc] initWithContentViewController: picker];
        self.popover.delegate =self;
        [self.popover presentPopoverFromRect:self.view.bounds inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
    }

    default:
        // Do Nothing.........
        break;

    }
}

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

    NSLog(@"Picker returned successfully.");

    UIImage *selectedImage;

    NSURL *mediaUrl;

    mediaUrl = (NSURL *)[info valueForKey:UIImagePickerControllerMediaURL];

    if (mediaUrl == nil) {

    selectedImage = (UIImage *) [info valueForKey:UIImagePickerControllerEditedImage];
    if (selectedImage == nil) {

        selectedImage= (UIImage *) [info valueForKey:UIImagePickerControllerOriginalImage];
        NSLog(@"Original image picked.");

         }
    else {

        NSLog(@"Edited image picked.");

         }    

    }

    [picker dismissModalViewControllerAnimated:YES];


    [self.imageButton setImage:selectedImage forState:UIControlStateNormal];
}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {

    [self dismissModalViewControllerAnimated:YES];
}
