IOS 把model数组中相同元素放到tableView的同一个

NSArray *dataArray = responseObject[@"data"];

[self . dateArray removeAllObjects];

[self.allArray removeAllObjects];

if (self.isLoading == NO) {

[self.allArray removeAllObjects];

}

for (NSDictionary *dic in dataArray) {

GoOutModel *model = [[GoOutModel alloc] init];

[model setValuesForKeysWithDictionary:dic];

NSArray * arra = [dic[@"publishTime"] componentsSeparatedByString:@" "];

NSString * str = arra[0];

[self.dateArray addObject:str];

[self.allArray addObject:model];

}

/////////关键字数组

NSMutableArray * tmpArray = [NSMutableArray array];

self . tmpDic = [NSMutableDictionary dictionary];

NSMutableArray * tmpArr2 =[[NSMutableArray alloc]initWithArray:self.dateArray];

//--------------这是用来保存model的数组

NSMutableArray * tmpArray00 = [NSMutableArray array];

NSMutableArray * tmpArr200 =[[NSMutableArray alloc]initWithArray:self.allArray];

for (int i =0;i<tmpArr2.count;i++) {

NSString * key =  tmpArr2[i];

/*

1.先对model里的关键字进行读取

2.看关键字是否在数组中存在

3.如果不存在就新创建一个数组 把关键字对应的i值所对应的model添加到数组里

如果存在就获取到key所在的数组 并把新的相同关键字的model添加进去

4.👌了
