Próbuję po prostu włączyć wybieranie wielu obrazów z photolibrary przy użyciuUIImagePickerController. Jestem stosunkowo nowyXCode i nie rozumiem, jak zezwolić użytkownikowi na wybranie wielu obrazów zUIImagePickerControler. To jest mój obecny kod. Pomóż jakiemukolwiek organowi wybrać wiele obrazówUIImagePickerController.

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

 {
      switch(buttonIndex)
      {
          case 0:

              [self takeNewPhotoFromCamera];
              break;

              case 1:
              [self choosePhotoFromExistingImages];
              default:

              break;
      }

 }

 - (void)takeNewPhotoFromCamera

 {
      if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera])
      {
          UIImagePickerController *controller = [[UIImagePickerController alloc] init];
          controller.sourceType = UIImagePickerControllerSourceTypeCamera;
          controller.allowsEditing = NO;
          controller.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:
 UIImagePickerControllerSourceTypeCamera];
          controller.delegate = self;
          [self.navigationController presentViewController: controller animated: YES completion: nil];
      }

 }

 -(void)choosePhotoFromExistingImages

 {
      if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypePhotoLibrary])
      {
          UIImagePickerController *controller = [[UIImagePickerController alloc] init];
          controller.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
          controller.allowsEditing = NO;
          controller.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:
 UIImagePickerControllerSourceTypePhotoLibrary];
          controller.delegate = self;
          [self.navigationController presentViewController: controller animated: YES completion: nil];
      }

 }


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

 {
      [self.navigationController dismissViewControllerAnimated: YES completion: nil];
      UIImage *image = [info valueForKey: UIImagePickerControllerOriginalImage];
      NSData *imageData = UIImageJPEGRepresentation(image, 0.1);

 }

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

 {
      [self.navigationController dismissViewControllerAnimated: YES completion: nil];
