Build Failed, after putting that block of code.

  • (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];

    if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) { // A photo was taken/selected! self.image = [info objectForKey:UIImagePickerControllerOriginalImage]; if (self.imagePicker.sourceType == UIImagePickerControllerSourceTypeCamera) { // Save the image! UIImageWriteToSavedPhotosAlbum(self.image, nil, nil, nil); }

    [self dismissViewControllerAnimated:YES completion:nil];
    

    } }

// this is giving me a build failed after i wrote this code.

Build Failed, Undefined symbols for architecture x86_64: "_kUTTypeImage", referenced from: -[CameraViewController imagePickerController:didFinishPickingMediaWithInfo:] in CameraViewController.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

someone could help me with this bug. i wrote the code exactly as in the video.
