ios - UITableView has extra space on top during "pull down to refresh" -

-

i have problem tableview. has space on top this: enter image description here

when open taskstableviewcontroller, problem doesn't show. when open viewcontroller tasktablevc this: 

 filtertaskstableviewcontroller * fttvc = [self.storyboard instantiateviewcontrollerwithidentifier:@"filtertaskstableviewcontroller"]; fttvc.delegate = self; uinavigationcontroller * navvc = [self.storyboard instantiateviewcontrollerwithidentifier:@"popovernavigationcontroller"]; [navvc setviewcontrollers:@[fttvc]]; [self presentviewcontroller:navvc animated:yes completion:nil];

and go tasktablevc, problem occurs. when "pull down refesh", goes normal.

in code tasktablevc: 

- (void)viewwillappear:(bool)animated { //other code [self populate]; }  - (void)viewdidload {   dispatch_async(dispatch_get_main_queue(), ^{     self.refreshcontrol = [[uirefreshcontrol alloc] init];      self.refreshcontrol.attributedtitle = [[nsattributedstring alloc] initwithstring:@" "];      [self.refreshcontrol addtarget:self action:@selector(refresh) forcontrolevents:uicontroleventvaluechanged];      [self setrefreshcontrol:self.refreshcontrol];  });      [self populate]; }  - (void)populate {  taskhandler *handler = [[taskhandler alloc] initwithcontext:_context]; nsarray *alltasks = [handler getall];  _tasks = [self filtertasks:alltasks];  nssortdescriptor *descriptor = [[nssortdescriptor alloc] initwithkey:@"startdate" ascending:no]; nsarray *descriptors = [nsarray arraywithobjects:descriptor, nil]; _tasks = [[nsmutablearray alloc] initwitharray:[_tasks sortedarrayusingdescriptors:descriptors]]; dispatch_async(dispatch_get_main_queue(), ^{     [self.tableview reloaddata];     [self.refreshcontrol endrefreshing]; });  }

i hope can me weird problem.

i solved problem code. thought there wrong refresh control moved out of dispatch_aysnc(dispatch_get_main_queue() , added [self.tableview reloaddata . fixed problem. answering. :)
