iOS Parse UISearchBar - ios

Question

I am new to iOS. I am making an app in which i am getting data from Parse back-end all are working fine.
I did UISearchbar and it works well. But when a search produces more than 6 results (main table have 6 rows, but I search for another Parse class) , this leads to an error.

Please help me! I can not solve the problem for several days. :'(

Try
dispatch_async(dispatch_get_main_queue(), ^{
[self.searchResults removeAllObjects];
[self.searchResults addObjectsFromArray:goodsList];
[self.searchController.searchResultsTableView reloadData];
});
to ensure editing your datasource and reloading your tablew view are done in the same dispatch queue.
