UITableViewCell selectedBackgroundView example in Objective C (iOS).

UITableViewCell selectedBackgroundView

The view used as the background of the cell when it is selected.

@property(nonatomic, retain) UIView *selectedBackgroundView

Discussion of [UITableViewCell selectedBackgroundView]
The default is nil for cells in plain-style tables (UITableViewStylePlain) and non-nil for section-group tables UITableViewStyleGrouped). UITableViewCell adds the value of this property as a subview only when the cell is selected. It adds the selected background view as a subview directly above the background view (backgroundView) if it is not nil, or behind all other views. Calling setSelected:animated: causes the selected background view to animate in and out with an alpha fade.

UITableViewCell selectedBackgroundView example.

    self.backgroundColor = [UIColor blackColor]; // Gives black background for you

    // Set selected background view
    UIView *backgroundView = [[UIView alloc]initWithFrame:self.bounds];
    backgroundView.layer.borderColor = [[UIColor colorWithRed:0.529 green:0.808 blue:0.922 alpha:1]CGColor];
    backgroundView.layer.borderWidth = 10.0f;
    self.selectedBackgroundView = backgroundView;
    [backgroundView release];

    // Set the content view
    CGRect frame  = CGRectMake(self.bounds.origin.x+5, self.bounds.origin.y+5, self.bounds.size.width-10, self.bounds.size.height-10);
    UIImageView *imageView = [[UIImageView alloc] initWithFrame:frame];
    self.imageView = imageView;
    [imageView release];
    self.imageView.contentMode = UIViewContentModeScaleAspectFill ;
    self.imageView.clipsToBounds = YES;
    [self.contentView addSubview:self.imageView];

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
        cell.selectedBackgroundView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"SelectedCellBackground.png"]] autorelease];
    }
