IOS create new UITableViewCell with properties of a prototype cell

I am working on an app that has several prototype cells in one view. This worked well for easily altering the appearance of the app while in development using the storyboard. However, now I'm adding search (filtering) capability. I would like the appearance of the tableview to remain unchanged, just filter out some of the results.

My understanding is that I have to create new cells to do this. Is this correct? If it is, is there a way to create a cell with all the properties of my prototype cells. As it is now, the newly created (search result) cells have default settings.

Thanks.

The thing to understand clearly is that the table view that appears when you are doing a search with the UISearchDisplayController conglomerate is not your table view. It is a different table view, and you do not have a UITableViewController managing it - the UISearchDisplayController does that. Thus you must take other measures if you want that different table view to look like your table view.

EDIT: On the whole (and after the little exchange with rdelmar in the comments on his answer), I tend to think the easiest solution is to abandon the use of cell prototypes altogether. If you design the cell in a nib (xib), you can then use that cell both for the real table and for the search results table. In both cases you register the nib with the respective table view - and then dequeue just does the right thing all by itself, in both cases, with no change in the code.

You can see me doing something similar here:

https://github.com/mattneub/Programming-iOS-Book-Examples/blob/master/ch21p632searchableTable/p536p550searchableTable/RootViewController.m

... except that in that case I'm registering the same cell class for both tables, not the same nib. But it all comes down to the same thing. However, note that I do not start with a storyboard, so I never fell into the trap of using a prototype cell in the first place.

You can certainly use copy and paste. Create a xib file (an empty one), and copy the cell you want from your table view in the storyboard, and then paste it into the xib file. In the viewDidLoad method for your table data source, register that nib file:

[self.searchDisplayController.searchResultsTableView registerNib:[UINib nibWithNibName:@"SearchCell" bundle:nil] forCellReuseIdentifier:@"SearchCell"];

Then in the cellForRowAtIndexPath method, you just dequeue a cell with that identifier for your search results table view.
