Get form values ​​from multivalued sections of an Eureka form

Ask this question because it is not yet covered in the docs and they track and respond to this tag. I am using Eureka to create a multivalued form. This is my code:

    +++ MultivaluedSection(multivaluedOptions: [.Reorder, .Insert, .Delete],
        header: "Options",
        footer: "footer") {
                            $0.addButtonProvider = { section in
                                return ButtonRow(){
                                    $0.title = "Add New Option"
                                }
                            }
                            $0.multivaluedRowToInsertAt = { index in
                                print(self.form.values())
                                return NameRow() {
                                    $0.placeholder = "Your option"
                                }
                            }
                            $0 <<< NameRow() {
                                $0.placeholder = "Your option"
                            }
    }

Now I want to extract all the values ​​in the NameRows at the end. There can be any number of lines (based on user input). This is what I tried:

self.form.values()

but this results in [ : ]

.

How do I get all the values?

For those with a similar problem:

form.values()

empty because there were no labels for the lines. To get values ​​from form

, give tags to strings and you will get a dictionary of values ​​with keys like these tags. Ad hoc



+++ MultivaluedSection(multivaluedOptions: [.Reorder, .Insert, .Delete],
                           header: "header",
                           footer: "footer") {
                            $0.addButtonProvider = { section in
                                return ButtonRow(){
                                    $0.title = "Button Title"
                                }
                            }
                            $0.multivaluedRowToInsertAt = { index in
                                return NameRow("tag_\(index+1)") {
                                    $0.placeholder = "Your option"
                                }
                            }
                            $0 <<< NameRow("tag_1") {
                                $0.placeholder = "Your option"
                            }
    }

Values ​​will now be returned as ["tag_1" : "value 1", "tag 2 : "value 2" ....]

for any number of rows inserted by the user.
PS: Used tag index

within tag because duplicate tags are not allowed and the meaning index

is different for different strings.

Form.value () returns a Dictionary and the dictionary has no ordering information.
Thus, you cannot get overridden values ​​from form.values ​​().

I got the orderd data like below:
(form.allRows returns Array and has order information.)



// Dictionary doen't have order info.
let values: Dictionary = form.values()
NSLog("LogA : %@", values)

// Array has order info, and this can return all tags.
let allRow: Array<BaseRow> = form.allRows
for i in 0..<allRow.count {
    let tmp: BaseRow = allRow[i]
    NSLog("LogB : %d : %@", i, tmp.tag ?? "")
}

// So make ordered data by from.values() and form.allRows like this.
var results: Array = [String]()
for i in 0..<allRow.count {
    let tag: String = allRow[i].tag ?? ""
    if(tag != ""){
        let val: String = values[tag] as! String
        results.append(tag + ":" + val)
    }
}
NSLog("LogC = %@", results)

As described here, just give a tag to each line;

<<< NameRow() {
$0.tag = "NameRow"
$0.title = "Name:"
$0.value = "My name" }

It's much easier

First of all, add a tag to the entire MultivaluedSection object.

    +++ MultivaluedSection(multivaluedOptions: [.Reorder, .Insert, .Delete],
    header: "Options",
    footer: "footer") {

                        $0.tag = "someTag" // added this line

                        $0.addButtonProvider = { section in
                            return ButtonRow(){
                                $0.title = "Add New Option"
                            }
                        }
                        $0.multivaluedRowToInsertAt = { index in
                            print(self.form.values())
                            return NameRow() {
                                $0.placeholder = "Your option"
                            }
                        }
                        $0 <<< NameRow() {
                            $0.placeholder = "Your option"
                        }
}

and then you can get the values ​​by

let values = (self.form.values()["someTag"]!! as! [Any?]).compactMap { $0 }
