NSDictionary allKeys订单

问题描述

我需要在UITableView中显示由API返回的NSDictionary的内容，尊重键的顺序。

I need to display in a UITableView the content of a NSDictionary returned by an API, respecting the order of the keys.

我正在使用：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
        NSString *key = self.data.allKeys[indexPath.section];
        NSArray *list = self.data[key];
        id data = list[indexPath.row];

        PSSearchCell *cell = [PSSearchCell newCellOrReuse:tableView];

        cell.model = data;

        return cell;
}

但我一样 self.data.allKeys ，我正在丢失我的钥匙的顺序。我无法按价值对它们进行排序，因为它与它们无关。

but as I do self.data.allKeys, I'm loosing the order of my keys. I can't sort them by value as it doesn't concern them.

推荐答案

正如大家所说，我可以因为NSDictionary日志中出现了我的密钥，因为没有订购NSDictionary。

As everyone said, I can't order my keys as they appear in my NSDictionary log because a NSDictionary is not ordered.

我要求API中的人返回一个数组：

I asked people from the API to return an array instead:

0 => name : key 1
     value : value 1

1 => name : key 2
     value : value 2

/ ----- -------------------------------------------------- --------------------- /

太糟糕了，没有方法 sortedArrayUsingArray就像这样使用：

Too bad there isn't a method "sortedArrayUsingArray" used like that :

NSArray * arrayOne = [@"key E", @"key A", @"key C"];

NSArray * arrayTwo = [@"key A", @"key B", @"key C", @"key D", @"key E", @"key F"];

NSArray * orderedArray = [arrayOne sortedArrayUsingArray: arrayTwo];
