按下按钮后更改原型单元中的标签

Question

I have set up a tableview using custom cells as such:-

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{SWHNearYouCell *cell = (SWHNearYouCell *)[tableView
                                  dequeueReusableCellWithIdentifier:@"NearYouCell"];

SWHNearYou *aPointer = [self.thingsNearYou objectAtIndex:indexPath.row];
cell.customNearYouLabel.text = aPointer.restrauntsNearYou;
return cell;
}

I want to change the text of customNearYouLabel upon a button press but work out how to get a pointer to the cell in my -IBAction method.

Thanks

Answer 1

You can just handle that in your tableView:didSelectRowAtIndexPath: method by grabbing the cell.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    cell.customNearYouLabel.text = @"New Text";
}

Answer 2

I presume the button is not on a table cell?

If so, you just need to update the relevant value in the self.thingsNearYou array.

If you then call [tableView reloadData] then the table will reload it's data and the text of customNearYouLabel will change.

Answer 3

Worked it out - needed to add in self before tableview

-(IBAction)cancel:(id)sender{


    SWHNearYouCell *cell = (SWHNearYouCell *)[self.tableView
                                          dequeueReusableCellWithIdentifier:@"NearYouCell"];

cell.customNearYouLabel.text = @"New Text";

 NSLog(@"This is it: %@",cell.customNearYouLabel.text);

}

I'll need to spend some more time on it as [self.tableView reloadData]; will not update the table but I reckon that should be easier to solve.
