iphone - Multiple cell selection In tableview

I want to upload photos to twitter , facebook and twit pic and many more. I took this in Array and displayed in Table view. I am using shareKit . I coded like if I select one cell (for eg.Twitter) then It will upload photo to twitter I want to select more than one cell and perform this sending action on one button(send to selected row item). I am able to mark/unmark cells but how to get selected value of cell. I dont want it to be in table's editing mode..

Code :

-  (void) tableView:(UITableView *)atableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {


    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    if (cell.accessoryType == UITableViewCellAccessoryCheckmark) {
        cell.accessoryType = UITableViewCellAccessoryNone;
    }


    else {

        cell.accessoryType = UITableViewCellAccessoryCheckmark;
    }



}

Let sourceArray be your array which you use to populate the tableview. And selectedObjects be an array of objects that are selected, initialized to contain 0 objects. It should be a (private) class instance variable.

//NSMutableArray *selectedObjects = [[NSMutableArray array] retain];

-  (void) tableView:(UITableView *)atableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    YouObjectType *object = [sourceArray objectAtIndex:indexPath.row]; //This assumes that your table has only one section and all cells are populated directly into that section from sourceArray.
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    if (cell.accessoryType == UITableViewCellAccessoryCheckmark) {
        cell.accessoryType = UITableViewCellAccessoryNone;
        [selectedObjects removeObject:object];
    }
    else {
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
        [selectedObjects addObject:object];
    }
}

Then in the sending action method of the button you described, use the objects in the selectedObjects array to do the required operation.
