I am creating a test tvOS app. I have an image (outside the tableview) and when "focused" NOT selected, I would like the image to change... I know that apple has added a couple methods for focus. Could someone tell me which methods I would use to change this image for when it is in "focus"? and how would I use it? Would I use this method:
- (BOOL)tableView:(UITableView *)tableView canFocusRowAtIndexPath:(NSIndexPath *)indexPath
or would I use:
- (void)tableView:(UITableView *)tableView didUpdateFocusInContext:(UITableViewFocusUpdateContext *)context withAnimationCoordinator:(UIFocusAnimationCoordinator *)coordinator
Please let me know! Thank you!
If you want to change image when UITableViewCell item get focus, then you should use second method.
- (void)tableView:(UITableView *)tableView didUpdateFocusInContext:(UITableViewFocusUpdateContext *)context withAnimationCoordinator:(UIFocusAnimationCoordinator *)coordinator
{
//You can get focused indexPath like below
NSIndexPath *nextIndexPath = [context nextFocusedIndexPath];
// Now get image from data source, I will assume you have an images array
UIImage *image = [_imagesArray objectAtIndex:nextIndexPath.row];
// Set image to image view, assuming you have a property imageView
_imageView.image = image;
}
