Search through the array in the searchbar - ios

Question

I took advantage of this article to create a search in my application. Slightly changed the code for yourself. But if I add to the array of multiple values (1-5), the search is working perfectly, but if you add an array of say 15 value, then an error takes off

Answer 1

I may understood your problem (or may not...). Check if you wrote the cell identifier (SearchResultsTableViewUITableViewCell) in your SearchResultsTableViewUITableViewCell.nib file (or SearchResultsTableViewUITableViewCell.m file instead).
I think that you didn't reused cells at all. For 5 cells you didn't need that, because the UITableView needed to create 5 cells anyway (the dequeue method create (tableHeight / cellHeight) cells, and all other cell are reused).
Another option, if you registered your class but not your nib file:
add
[self.yourTableView registerNib:[UINib nibWithNibName:#"SearchResultsTableViewUITableViewCell" bundle:nil]
forCellReuseIdentifier:#"SearchResultsTableViewUITableViewCell"];
