arrays - 基于另一个数组的Swift Sort数组

这个问题已经有了答案：
Sort array by order of values in other array [duplicate]
4个答案
所以我有两个数组

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

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

注意-tmparray可以包含所有或部分“knownorder”数组对象。
现在我要做的是根据“knownorder”对“tmparray”进行排序。
我能做什么？

最佳答案

过滤knownOrder以移除任何不在tmpArray中的元素：

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)
