 You might be calling  show  with background code , Call it at the main thread like this:  
  UIAlertView * alert = [[UIAlertView alloc] initWithTitle: @ "Hello!" Message: @ "Hello!" Representative: cancel itselfTuttonite: @ "finished" other button titles: zero]; [Warning Exhibitor ChoosesMindThread: @Selector (Show) with object: Wait until zero: no]; [Warning issued];
