It blocks UI if I pick many photos about qbimagepicker

This won't help. Because, the program will run the main thread code until
info is complete.
That is to say, you pick a lot of photos, then you click OK. Nothing
happens (the user can still do other operations) until the background
thread finish processing assets.

• (void)assetCollectionViewController:(QBAssetCollectionViewController *)assetCollectionViewController didFinishPickingAssets:(NSArray *)assets{
  if([self.delegate respondsToSelector:@selector(qbImagePickerControllerWillFinishPickingMedia:)]) {
  [self.delegate qbImagePickerControllerWillFinishPickingMedia:self];
  }

  if([self.delegate respondsToSelector:@selector(qbImagePickerController:didFinishPickingMediaWithInfo:)]) {
  dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, NULL), ^{
  NSMutableArray *info = [NSMutableArray array];
  for(ALAsset *asset in assets) {
  [info addObject:[self mediaInfoFromAsset:asset]];
  }
  dispatch_async(dispatch_get_main_queue(), ^{
  [self.delegate qbImagePickerController:self didFinishPickingMediaWithInfo:info];
  });
  });

  }}

Would be a non thread blocking way.

I already saw and removed the post. Its late :-P about the only thing you
can do is trigger a delegate call for each image spit out. But that gets
really annoying to handle. I limit selection to 8 on my own because it
uploads after selection.
