iPhone: Coding a done button in UITableViewCell

I spent a few hours coding a UITableViewCell to look and function as an iphone button in a grouped UITableView and thought others might appreciate the code.

(The button look isn't perfect, I'll probably spend some more time getting the "light" just right on it.)

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {/* other stuff */

        static NSString *DoneButtonCellIdentifier = @"DoneButtonCell"; 

        cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:DoneButtonCellIdentifier];

           
        if (cell == nil) {
                // Create a cell to display an emotion.
                cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:DoneButtonCellIdentifier] autorelease];
                cell.accessoryType = UITableViewCellAccessoryNone;
            }   
   
            //creates the button look
            UIView *view = [[[UIView alloc] initWithFrame:CGRectMake(10, 0, 280, 43)] autorelease];
            CAGradientLayer *gradient = [CAGradientLayer layer];
            [gradient setCornerRadius:9.0f];
            [gradient setMasksToBounds:YES];
            [gradient setBorderWidth:0.8f];
            [gradient setBorderColor:[[UIColor darkGrayColor] CGColor]];
            gradient.frame = view.bounds;
            gradient.colors = [NSArray arrayWithObjects:(id)[[UIColor greenColor] CGColor], (id)[[UIColor colorWithRed:.05 green:.65 blue:.05 alpha:1] CGColor],(id)[[UIColor colorWithRed:.05 green:.65 blue:.05 alpha:1] CGColor], (id)[[UIColor colorWithRed:.05 green:.45 blue:.05 alpha:1] CGColor], nil];
            gradient.locations = [NSArray arrayWithObjects:[NSNumber numberWithFloat:0.10],[NSNumber numberWithFloat:0.49],[NSNumber numberWithFloat:0.51],[NSNumber numberWithFloat:1.0]];

            [view.layer insertSublayer:gradient atIndex:0];                       
            [cell.contentView addSubview:view];
           
            //"button" label
            UILabel *label = [[[UILabel alloc] initWithFrame:CGRectMake( 10, 0.0, 280, 43)] autorelease];
            label.textAlignment = UITextAlignmentCenter;
            label.font = [UIFont boldSystemFontOfSize:20.0];
            label.textAlignment = UITextAlignmentCenter;
            label.textColor = [UIColor whiteColor];
            label.shadowColor = [UIColor lightGrayColor];
            label.autoresizingMask = UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleHeight;
            label.backgroundColor = [UIColor clearColor];
            label.text=@"Done";
            [cell.contentView addSubview: label];
           
            //makes cell transparent
            UIView *backView = [[[UIView alloc] initWithFrame:CGRectZero] autorelease];
            backView.backgroundColor = [UIColor clearColor];
            cell.backgroundView = backView;
           
            return cell;
