Void SendDelegateMessage (NSInvocation *): The delegate could not return after waiting 10 seconds. how to delete such messages

Question

I load data into NSdata before viewdidload

I got the 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. 

Answer 1

I would advise you not to do something on your main thread, which will take 10 seconds at startup. Show some user interface, use the background thread to load large data sets.
