I have a tableView that’s loosely based on the DetailViewController in ye olde SQLiteBooks. It’s created programatically. Each cell displays a single value that when clicked displays a generic editingController that allows the user to edit that value. Pretty standard Cocoa-touch stuff…

Except…I also have a segmented control in the header of said tableView that depending on it’s setting needs to change an attribute (textColor) on a UILabel in ONE of the 8± tableViewCells in the table. I have no IBOutlets for this tableView because I created it entirely in code. So, what do I need to do in my (void)segmentAction:(id)sender method (triggered when segmentedControl changes state) to allow me to access & change this value and display it to the user? When the table was built (cellForRowAtIndexPath) every UILabel was called “value” and then added: [cell.contentView addSubview:value].

I’ve tried setting a property of the viewController itself that is then checked during cellForRowAtIndexPath and does the textColor business there…and then adding [self.tableView setNeedsDisplay] to my segmentAction: method but it doesn’t seem to work?!?

Any ideas?

    In the class that implements cellForRowAtIndexPath you could also store a reference to the UILabel that you want when you build the relevant cell.

    This would then mean you could alter the label and mark it to be repainted.

    Alternately you could hold a local BOOL to show that the cell should be drawn differently – and then use this this in the cellForRowAtIndexPath: to draw it with a background.

    You might find this easier with the 3.0 textLabel object in a UITableViewCell
