尤里卡通过标签获取SelectableSection

Question

我有这样的代码：

    form +++= SelectableSection<ImageCheckRow<String>, String>("branch_section", selectionType: .MultipleSelection) { section in
        section.header = HeaderFooterView(title: "Branches")
    }

    for branch in sharedBranch.branchList {
        form.last! <<< ImageCheckRow<String>(branch.name){ row in
            row.title = branch.name
            row.baseValue = branch.id
            row.selectableValue = branch.name
            row.value = nil
        }
    }

但我找不到selectedRows，我试过：

    let branch_section = self.form.sectionByTag("branch_section") as? SelectableSection<ImageCheckRow<String>, String>
    print(branch_section)
    print(branch_section.selectedRows())

两种打印nil

Answer 1

为了做到这一点，您需要使用这个

form +++= SelectableSection<ImageCheckRow<String>, String>("branch_section", selectionType: .MultipleSelection)
form.last!.header = HeaderFooterView(title: "Branches")
form.last!.tag  = "branch_section"

而不是

form +++= SelectableSection<ImageCheckRow<String>, String>("branch_section", selectionType: .MultipleSelection) { section in
    section.header = HeaderFooterView(title: "Branches")
}

然后你的代码

let branch_section = self.form.sectionByTag("branch_section") as? SelectableSection<ImageCheckRow<String>, String>
print(branch_section)
print(branch_section.selectedRows())

我希望这对你有帮助
