我试图只使用 UIImagePickerController 从影像库中选择多个图像。我对 XCode 我不明白如何允许用户从 UIImagePickerControler 中选择多个图像。这是我目前的代码。请帮助任何人如何从 UIImagePickerController 中选择多个图像。

I am trying to simply enable picking multiple images from photolibrary using the UIImagePickerController.I'm relatively new to XCode and I don't understand how to allow the user to pick multiple images from the UIImagePickerControler. This is my current code.Please help any body how to pick multiple images from UIImagePickerController.

 -(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];

 }

推荐答案

带 UIImagePickerController 你只能得到一张照片。如果您需要选择更多，则需要自定义图像选择器，例如 ELCImagePickerController 。它运作良好！您可以这里下载它。

With UIImagePickerController you are able to get only one picture. If you need to pick more you need a custom image picker, such as ELCImagePickerController. It works well! You can download it here.
