tableView.reloadData（）在覆盖函数

Question

在底部代码中，tableView.reloadData（）在我在overriden函数中使用时工作，并且在OM_Status的didSet函数中不起作用... 有谁知道问题是什么？！ OM_Status将通过 lptvc var在其他swift文件中的运行时更改... .................................................. .......................................

#imageLiteral(resourceName: "noormakhof") , #imageLiteral(resourceName: "halojenoff")]

var OMStatus : Int? {
    didSet {
        for index in 0..<lampImage.count {
            switch index {
            case 0 , 1 :
                lampImage[index] = OMStatus! & power(2, index) != 0 ? #imageLiteral(resourceName: "loosteron") : #imageLiteral(resourceName: "loosteroff")
