Swift Eureka ios：如何通过if声明更改0.5美元的期权

我需要根据用户选择的另一行更改一行的选项

我使用这个代码，它没有改变

<<< PushRow<String>(kEncryption) {
                $0.title = "Encryption"
                if let r1 : PushRow<aType> = form.rowBy(tag: kProxyFormType), let a = r1.value?.isA, let b = r1.value?.isB {
                        print(a)
                        if (a) {
                            $0.options = ["1","2","3"]
                        }
                        else if (b) {
                            $0.options = ["4","5","6"]
                        }
                    }

反过来，在
PushRow
的
onChange
关闭中更改
PushRow
的选项，类似于

<<< PushRow<aType>(kProxyFormType) { 
   ...
}.onChange { row in 
    if let encryptionRow = self.form.rowBy(tag: kEncryption) as? PushRow<String> {
       if row.value?.isA {
           encryptionRow.options = ["1","2","3"]
       } else if row.value?.isB {
           encryptionRow.options = ["4","5","6"]
       }
    }
}

           encryptionRow.options = ["1","2","3"]
       } else if row.value?.isB {
           encryptionRow.options = ["4","5","6"]
       }
    }
