Question

On an app I’m working on for the iPhone, it has decided to not compile on me when I ask it to give me an outlet to a label on a prototype table cell. I’ve gotten outlets for labels before, but I was using either just a standard view or static cells rather than prototype cells. I’m thinking it probably has to do with the fact that the label belongs to a prototype cell and will be duplicated since they all have the same identifier (Cell), but then again I could be off. I’m not sure what to do with this one, if I use just cell.textLabel.text then my upload button doesn’t show up until after I click on the cell.

The Error:

Couldn't compile connection: <IBCocoaTouchOutletConnection:0x4007cd200  <IBProxyObject: 0x4007de280> => lblServerName2 => <IBUILabel: 0x4009b7d00>>

Does anyone have any suggestions as to how I could go about setting the text on a custom label inside a cell?

For reference, I’ve uploaded my project here. It’s a mess at the moment, but it’s currently just a proof on concept kind of thing. I’m going to go through and do clean up once I get it working.

Any suggestions are appreciated.

EDIT:

This page helped out. I found it almost immediately after posting this question. Basically, I set the tag of my label to 100 and then used this code inside of the cellForRowAtIndexPath method.

UILabel *lblServerName = (UILabel*)[cell viewWithTag:100];
lblServerName.text=[server getName];

and there it was, my label working correctly and my button showing up.

To change the text in a label on an arbitrary UITableViewCell, assign a tag to the label, and then in code do something like the following:

UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:[NSIndexPath indexPathWithIndex:2]];
if (cell != nil) {
    // This assumes that you set the tag to 1 on the label
    UILabel *label = (UILabel *)[cell viewWithTag:1];
    label.text = @"New Text";
}
