Question

I Have two collectionView one is for main items and other is for Sub Items

Main Item we can consider as iPhone

Sub Items we can consider as headphone of apple

so we can say this two items “One Group”

both items are adding at DidSelectMethod and displaying in tableView

i have one option of delete this item

my requirement is if i delete any of one item from this group my all tableview data should be cleared

Here is the Code i am using to delete Product

//Define Button Action in cellForRowAtIndexPath

cell.btnDelete.addTarget(self, action:#selector(ViewController.btnDeleteTapped(_:)), forControlEvents: .TouchUpInside)
cell.btnDelete.tag = indexPath.row

//Button Action

func btnDeleteTapped(sender: UIButton){

  self.arrProductCart.removeObjectAtIndex(sender.tag)
  self.tblCart.reloadData()
}

MainProduct Array

(
    {
    "addtional_price" = 0;
    "barcode_image" = ".png";
    "cart_unique_id" = 6;
    "chicken_product" = all;
    "created_by" = 2;
    "created_date" = "2015-11-19 21:39:24";
    "deleted_date" = "0000-00-00 00:00:00";
    ids = 151;
    isFromMain = 1;
    "is_deleted" = 0;
    "is_has_addtional_price" = 0;
    "parent_product_unique_id" = 6;
    "product_id" = 53;
    "product_name" = "Black Pepper Chicken";
    "product_parent_id" = 0;
    "product_price" = "7.9";

    "update_date" = "2016-06-22 17:54:53";
    "updated_by" = 7;
  "parent_product_unique_id" = 6
}
