弹出所选单元格后，使用RSSelectionMenu库更新按钮标题

Question

我发现用弹出的RSSectionMenu库看here后，用我所选择的单元格的值更新UI按钮的文本，我可以执行以下操作：

selectionMenu.setSelectedItems(items: simpleSelectedArray) { (text, isSelected, selectedItems) in

    // update your existing array with updated selected items, so when menu presents second time updated items will be default selected.
    self.simpleSelectedArray = selectedItems
}

我尝试在我的代码中执行此操作，但它不起作用。当我打印simpleSelectedArray时它是空的。那么请问我如何收集选定的单元格值并更新我的标题按钮。我是Swift的初学者，谢谢！

这是我如何使用POD包括第一条评论中给出的建议。

 @IBAction func CategoryTapped(_ sender: Any) {

            let simpleDataArray = cat //I COLLECT cat for category and catID for category ID from my API

            let simpleDataArrayID = catId

            let selectionMenu =  RSSelectionMenu(dataSource: simpleDataArray) { (cell, object, indexPath) in
                cell.textLabel?.text = object
                cell.tintColor = .orange
            }
            selectionMenu.setSelectedItems(items: simpleSelectedArray) { (text, isSelected, selectedItems) in
        self.simpleSelectedArray.append(contentsOf: selectedItems)
        self.simpleSelectedArrayID.append(contentsOf: simpleDataArrayID)

for j in 0 ..< self.simpleSelectedArray.count {
         self.categoryupdate = self.simpleSelectedArray[j]

         self.EditCategory.setTitle(self.categoryupdate,for: .normal)

       self.categoryupdateID = self.simpleSelectedArrayID[j]

}
   self.updateAdcat(Category: self.categoryupdateID ) // Here I want to update my category by sending the ID of the selected category to the server. updateAdcat(id: Int) is my update function
            }

        selectionMenu.show(style: .Push, from: self)
        }

现在的问题是我无法更新按钮标题并收集正确的相应ID。所选标题和Id不对应。
