基于另一个数组的Swift Sort数组

Question

所以我有2个阵列

let knownOrder = ["Headache level", "Headache side", "Nausea", "Aura", "Phonophobia" ,"Photophobia"]

let tmpArray = ["Aura","Headache side","Photophobia"]

• 注意 - tmpArray可以包含全部或部分已知订单＆＃39;数组对象。

现在我要做的是对“tmpArray”进行排序。按照“已知订单”的顺序排列。

我该怎么办？

Answer 1

过滤knownOrder以删除tmpArray中没有的任何元素：

let knownOrder = ["Headache level", "Headache side", "Nausea", "Aura", "Phonophobia" ,"Photophobia"]

let tmpArray = ["Aura","Headache side","Photophobia"]

let ordered = knownOrder.filter { tmpArray.contains($0) }
print(ordered)
