Eureka Swift-位置行的设置值
我有一个表单,用户可以从包含坐标数据的多个对象中进行选择,我希望将坐标数据加载到LocationRow中 我尝试了几种不同的方法来尝试设置Location行值,但它要么崩溃(在展开可选值时意外地发现nil),要么没有用正确的数据重新加载表。i、 e My LocationRow eureka代码:Eureka Swift-位置行的设置值,swift,eureka-forms,Swift,Eureka Forms,我有一个表单,用户可以从包含坐标数据的多个对象中进行选择,我希望将坐标数据加载到LocationRow中 我尝试了几种不同的方法来尝试设置Location行值,但它要么崩溃(在展开可选值时意外地发现nil),要么没有用正确的数据重新加载表。i、 e My LocationRow eureka代码: $0.rowRight = LocationRow(){ $0.title = "Location" $0.tag =
$0.rowRight = LocationRow(){
$0.title = "Location"
$0.tag = "location"
if let page = selectedPage {
if let pageLocationLatitude = page.locationLatitude.value,
let pageLocationLongutude = page.locationLongitude.value {
print("testing for row update")
$0.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,我可以看到您正在将此位置行置于
拆分行中
:
// rowRight is a property of SplitRow
$0.rowRight = LocationRow(){
因此,表单并不真正了解位置行。它只知道拆分行。您应该首先使用其标记获取拆分行,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()
//在此处使用拆分行的标记!
让splitRow=self.form.rowBy(标记:“splitRow”)
作为!SplitRow//将SomeRow替换为拆分行左侧的行类型
让locationRow=splitRow.rowRight
locationRow.value=CLLocation(纬度:locationLatitude,经度:LocationLength)
locationRow.updateCell()位置
