iOS 8 UITableViewRowAction: Swipe Left, Images?

Question

I've just come across this new API on iOS8. I cannot however find any solution on if it is possible to use images instead of text and to allow left and right swipe? Is this even possible? The only implementation I've found is this:

- (NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath {

    UITableViewRowAction *moreAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleNormal title:@"Button1" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath){
        // maybe show an action sheet with more options
        [self.tableView setEditing:NO];
    }];
    moreAction.backgroundColor = [UIColor blueColor];

    UITableViewRowAction *moreAction2 = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleNormal title:@"Button2" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath){
        [self.tableView setEditing:NO];
    }];
    moreAction2.backgroundColor = [UIColor blueColor];

    UITableViewRowAction *deleteAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDestructive title:@"Delete"  handler:^(UITableViewRowAction *action, NSIndexPath *indexPath){
        [self.tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
    }];

    return @[deleteAction, moreAction, moreAction2];
}

Answer 1

No, I don't think it's possible to have a right swipe (with a UITableViewCell, anyway). However, you can use an image for the button by setting its background color using colorWithPatternImage:. The width of the button seems to be determined by the length of the title, so if you want to change the width (and not have any visible title), use a title that consists of as many spaces as you need.

Answer 2

在Swift中它将是：

deleteAction.backgroundColor = UIColor(patternImage: UIImage(named:"sample")!)

Answer 3

将图像添加到滑动视图时，此答案可能会有所帮助。
