iOS去除数组中重复的model数据

    // 去除数组中model重复
    for (NSInteger i = 0; i < self.selectedModelArray.count; i++) {
        for (NSInteger j = i+1;j < self.selectedModelArray.count; j++) {
            AssistantModel *tempModel = self.selectedModelArray[i];
            AssistantModel *model = self.selectedModelArray[j];
            if ([tempModel.assistantId isEqualToString:model.assistantId]) {
                [self.selectedModelArray removeObject:model];
            }
        }
    }

解释:

1.selectedModelArray是数据源数组;

2.两层循环判断model重复,因为数组中model地址都是不同的,只能通过model中唯一标示assistantId判断;

3.相等则移除即可.

4.循环结束,selectedModelArray数据源数组保存的是没有重复的model数据.
