Eureka Swift - 设置 LocationRow 的值

Question

我有一个表单，用户可以在其中从包含坐标数据的多个对象中进行选择，我想将这些数据加载到 LocationRow 中。

我尝试了几种不同的方法来尝试设置 Location Row 值，但它要么崩溃（在展开可选值时意外发现 nil），要么没有用正确的数据重新加载 table。即 https://i.imgur.com/2XkeHbu.png

我的 LocationRow 尤里卡代码：

[=11=].rowRight = LocationRow(){
                    [=11=].title = "Location"
                    [=11=].tag = "location"
                    if let page = selectedPage {
                        if let pageLocationLatitude = page.locationLatitude.value,
                            let pageLocationLongutude = page.locationLongitude.value {
                            print("testing for row update")
                            [=11=].value = CLLocation(latitude: pageLocationLatitude, longitude: pageLocationLongutude)
                        }
                    }

                }

以及当我想更新 LocationRow 时调用的函数

 private func setSelectedPage(pageName : String) {
        print("setting location of page: \(pageName)")
        if pageName == username {
            return
        }
        selectedPage = userPages?.filter("name == \"\(pageName)\"").first
        if let locationLongitude = selectedPage?.locationLongitude.value,
            let locationLatitude = selectedPage?.locationLatitude.value {

        print("lat and lon: \(locationLatitude) \(locationLongitude)")

        /*PURELY FOR TESTING
        let titleRow = self.form.rowBy(tag: "title") as! TextRow
        titleRow.value = "TEST WORKS OK"
        titleRow.updateCell()
        PURELY FOR TESTING */

        let locationRow = self.form.rowBy(tag: "location") as! LocationRow
        locationRow.value = CLLocation(latitude: locationLatitude, longitude: locationLongitude)
        self.form.rowBy(tag: "location")?.updateCell()
    }


   self.tableView.reloadData()
}

从您的代码中，我可以看到您将此位置行放在 SplitRow:

// rowRight is a property of SplitRow
[=10=].rowRight = LocationRow(){

因此，表单并不真正了解位置行。它只知道拆分行。您应该首先使用 its 标签获取拆分行，然后访问 rowRight.

// use the tag of your split row here!
let splitRow = self.form.rowBy(tag: "splitRow") 
                    as! SplitRow<SomeRow, LocationRow> // replace SomeRow with the type of row on the left of the split row
let locationRow = splitRow.rowRight
locationRow.value = CLLocation(latitude: locationLatitude, longitude: locationLongitude)
locationRow.updateCell()
