如何从2 NSMutableArray比较和删除常见对象（NSDictionaries）？ [英] How to compare and remove common objects( NSDictionaries) from 2 NSMutableArray?

问题描述

我有两个NSMutableArrays，填充字典对象，如

I have two NSMutableArrays, filled with dictionary objects, like

NSMutableArray * bigArray = @[dictionary1,dictionary2,dictionary3];
NSMutableArray * smallArray = @[dictionary1];

我想从大数组中删除公共元素（dictionay1）

I want to remove the common elements (dictionay1) from the big array

注意：小数组是大数组和元素的子集。

Note: small array is subset of big array and elements are distinct

推荐答案

[bigArray removeObjectsInArray:smallArray];

删除 bigArray 中包含的所有对象在 smallArray 。

removes all objects in bigArray that are contained in smallArray.
