如何在目标C中交叉两个数组？ [英] how to intersect two arrays in objective C?

问题描述

我有两个数组。 Array1包含15个对象，Array2包含4个对象。两个数组都有两个常见的对象，我只想得到那两个对象的结果数组。

I have two arrays . Array1 contains 15 objects and Array2 contains 4 objects. There are 2 common objects from both array, I just want to get that resulted array of that 2 objects.

它应该像两个Set的交集，但是如何在Objective C中为数组做什么？请帮忙。谢谢。

It should be like intersection of two Set, but how to do in Objective C for array..? Please help. thanks.

推荐答案

使用NSMutableSet

Using NSMutableSet

NSMutableSet *set1 = [NSMutableSet setWithArray: array1];
NSSet *set2 = [NSSet setWithArray: array2];
[set1 intersectSet: set2];
NSArray *resultArray = [set1 allObjects];
