Question

I am making a bookmarks page for my web browser and the problem is that everytime I add a new object, I have to set the properties since I created a custom cell (I must set the text of two labels) and so I need a way to only edit the newly added object…I’m familiar with indexes but not able to come up with any solutions to this problem…For example when I bookmark the first page its fine, but once I bookmark 2 pages the 2 cells are the exact same…Any Ideas?

Heres My Code:

// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

static NSString *CellIdentifier = @"CustomCell";

CustomCell *cell = (CustomCell*)
[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:nil options:nil];
    cell = (CustomCell *) [nib objectAtIndex:0];

}

// Set up the cell...

     NSString *theTitle=[webView stringByEvaluatingJavaScriptFromString:@"document.title"];
NSString *currentURL = webView.request.URL.absoluteString;
      cell.websiteTitle.text = theTitle;
cell.websiteURL.text = currentURL;
universalURL = currentURL;




return cell;
}

When setting up the cell I need to point to the newest cell!

Thank You In Advance!

Your approach cannot work. You cannot use the cells as the store for the titles and URLs, because cells are reused (and because it is bad design). A table view allocates only cells for the visible rows and reuses a cell for a different row when you scroll the table view.

Instead you should store the titles and URLs in a separated data source, for example an NSMutableArray *bookmarks where each item in the array is a NSDictionary with “title” and “URL” keys.

To add a bookmark to your table, you just append a new entry to the array and call reloadData on the table view.

The tableView:cellForRowAtIndexPath: method can then use the bookmarks array with the row number indexPath.row to fill all elements of the cell.
