如何从相机视图访问图库？

Question

我正在寻找允许用户从相机视图访问图库的方式。

默认情况下，一个具有明确设置源类型UIImagePickerController

self.myPickerController.sourceType = UIImagePickerControllerSourceType.camera 

有没有什么办法让它在路上像机iOS相机应用？注意微小的画面中左下角

你就可以有呈现给用户两种选择，并允许他们从相册选择照片或用相机

 if (optionId == 1) { 
 
      if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) { 
 
       imagePicker = [[UIImagePickerController alloc] init]; 
 
       imagePicker.delegate = self; 
 
       imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera; 
 
       imagePicker.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, kUTTypeImage, nil]; 
 
       imagePicker.allowsEditing = NO; 
 
       
 
       imagePicker.modalPresentationStyle = UIModalPresentationFullScreen; 
 
       
 
       [self presentViewController:imagePicker animated:YES completion:nil]; 
 
      }else { 
 
       UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:@"Error" message:[NSString stringWithFormat:@"Camera not supported."] delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil]; 
 
       [alertView show]; 
 
      } 
 
      
 
     }else if (optionId == 2) { 
 
      imagePicker = [[UIImagePickerController alloc] init]; 
 
      imagePicker.delegate = self; 
 
      if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeSavedPhotosAlbum]) { 
 
       imagePicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum; 
 
      } else { 
 
       imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
 
      } 
 
      imagePicker.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, kUTTypeImage, nil]; 
 
      imagePicker.allowsEditing = NO; 
 
      
 
      imagePicker.modalPresentationStyle = UIModalPresentationFullScreen; 
 
      [self presentViewController:imagePicker animated:YES completion:nil]; 
 
     }
