ios - 重新加载视图时，Xcode Swift IOS Eureka LabelRow 不更新标题

Question

返回到包含以下代码的视图时，LabelRow $0.title 未更新。

从更改全局变量的“推送”视图返回后，如何让 LabelRow 更新其标题？

form +++

        Section("Current Person")
        <<< LabelRow {
            $0.title = currentPersonName  // "currentPersonName" is a global variable
            $0.tag = "Person"
        }.cellUpdate { cell, _ in
            cell.row.title = currentPersonName // set title to "currentPersonName"
            print("cellUpdate shows \(currentPersonName)") // verify "currentPersonName" change
        }.onCellSelection { _, _ in
            // the following view controller sets "currentPersonName" to something new
            let PersonPicker = PersonPicker()
            self.navigationController?.pushViewController(PersonPicker, animated: false)
            print("onCellSelection shows \(currentPersonName)") // verify "currentPersonName" change
        }

这是我为“修复”它所做的：

override func viewDidAppear(_ animated: Bool)
{
    if let row = self.form.rowBy(tag: "Person")
    {
        row.title = currentPersonName
        row.reload()
    }
}

但这是最好的解决方案吗？
