Error Domain=PlugInKit Code=13 "query cancelled" UserInfo={NSLocalizedDescription=query cancelled} with Objective C Xcode 9.3 iOS 11

Question

I'm using UIImagePickerController to get image from device. I've implemented the following steps:

1. Permission is taken: Privacy - Photo Library Usage Description - info.plist

2. Instance of UIImagePickerController is created and presented. Delegate is assigned to self. Camera or Library options are given with UIAlertController.

   -(void) openGallery {
       UIImagePickerController *picker = [[UIImagePickerController alloc] init];
       picker.delegate = self;
       picker.allowsEditing = YES;
   
       UIAlertController *actionSheet = [UIAlertController alertControllerWithTitle:nil message:nil preferredStyle:UIAlertControllerStyleActionSheet];
   
       [actionSheet addAction:[UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {
       }]];
   
       [actionSheet addAction:[UIAlertAction actionWithTitle:@"Camera" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
           // take photo button tapped.
           picker.sourceType = UIImagePickerControllerSourceTypeCamera;
           [self presentViewController:picker animated:YES completion:NULL];
       }]];
   
       [actionSheet addAction:[UIAlertAction actionWithTitle:@"Photo Library" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
           // PhotoLibrary
           picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
           [self presentViewController:picker animated:YES completion:NULL];
       }]];
   
       [self presentViewController:actionSheet animated:YES completion:nil];
   }
   

3. On delegate, image has arrived but, when I tried to upload it to server after converting it into base64, the AFNetworking threw error:

   Error Domain=PlugInKit Code=13 "query cancelled" UserInfo={NSLocalizedDescription=query cancelled} with Objective C Xcode 9.3 iOS 11

   #pragma mark- UIImagePicker Delegate
   
   - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{
       UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
   
       [picker dismissViewControllerAnimated:YES completion:NULL];
   
       [self.view setUserInteractionEnabled:NO];
       [self uploadThemeServiceCall: chosenImage];
   }
   

I tried creating OS_ACTIVITY_MODE to disable in environment variable, but it didn't work. I tried other solutions available but still it din't work. It was working fine but now it's not.

Answer 1

A:) Make sure object chosenImage is not nil. B:) Use NSData *imageData = UIImageJPEGRepresentation(imageObject , 1) to convert chosenImage into NSData . Use this imageData as ur NSUrlRequest body.

Alse show your code for Function uploadThemeServiceCall here.
