void SendDelegateMessage(NSInvocation*): delegate failed to return after waiting 10 seconds. how to remove this kind of messages

Question

I am loading the data in the NSdata before viewdidload

I got following message

void SendDelegateMessage(NSInvocation*): delegate failed to return after waiting 10 seconds. main run loop mode: kCFRunLoopDefaultMode
If you were not using the touch screen for this entire interval (which can prolong this wait), please file a bug.

I'd suggest not doing something on your main thread which will take 10 seconds at startup. Show some UI, use a background thread to load large data sets.
