APPaginalTableViewExample[16301:1734273] unexpected nil window in _UIApplicationHandleEventFromQueueEvent, _windowServerHitTestWindow: <UIClassicWindow: 0x7ff5fbd111c0; frame = (0 0; 375 667); userInteractionEnabled = NO; gestureRecognizers = <NSArray: 0x7ff5fbd13ff0>; layer = <UIWindowLayer: 0x7ff5fbe09670>>
