具有多个 TableView 键的 NSArray

Question

我正在开发一个天气应用程序。我获取了预测数据，预测的每一天都有一个 NSArray。该数组如下所示：

(
        {
        apparentTemperatureMax = "73.44";
        apparentTemperatureMaxTime = 1467500400;
        apparentTemperatureMin = "47.12";
        apparentTemperatureMinTime = 1467457200;
        cloudCover = "0.75";
        dewPoint = "43.53";
        humidity = "0.58";
        icon = rain;
        moonPhase = "0.9399999999999999";
        ozone = "276.53";
        precipIntensity = "0.0036";
        precipIntensityMax = "0.0092";
        precipIntensityMaxTime = 1467504000;
        precipProbability = "0.44";
        precipType = rain;
        pressure = "1015.28";
        summary = "Light rain starting in the afternoon.";
        sunriseTime = 1467460332;
        sunsetTime = 1467513207;
        temperatureMax = "73.44";
        temperatureMaxTime = 1467500400;
        temperatureMin = "47.12";
        temperatureMinTime = 1467457200;
        time = 1467439200;
        windBearing = 281;
        windSpeed = "0.54";
    }
)

我把所有的日子合为一个巨人NSMutableArray。我想做的是将 NSMutableArray 作为 UITableView 的来源，但只输入一些天气数据，如 temperatureMin、temperatureMax、precipProbability 等。对我来说，采用包含多个数组的 NSMutableArray 并且只显示每个数组的一些信息的最佳方式是什么？

更新：

这是完整的 NSMutableArray：

Answer 1

table.

源码中数组有两种使用方式

1- 你可以从数组中获取值 - 前-

NSString * temperatureMax_Str = [NSString stringWithFormat:@"%@",[[Array objectAtIndex:indexPath.row] valueForKey:@"temperatureMax"]];

2- 创建一个 NSDictionary 并添加数组中的值 -

NSDictionary *Dic = [Array objectAtIndex:indexPath.row];
 NSString * temperatureMax_Str = [Dic  valueForKey:@"temperatureMax"];

还有其他一些方法，您也可以尝试创建 mutable 字典等

Answer 2

使用此单行代码为您的 cellForRowAtIndexpath、

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {


    sampleTableCell *cell=[tableView dequeueReusableCellWithIdentifier:@"TableCellIdenfier"];
    if (!cell) {
        [tableView registerNib:[UINib nibWithNibName:@"TableCell" bundle:nil] forCellReuseIdentifier:@"TableCell"];
        cell=[tableView dequeueReusableCellWithIdentifier:@"TableCell"];
    }

    // Configure the cell...

    cell.temperatureLabel.text = [[[YourArrayName objectAtIndex:0] objectAtIndex:indexPath.row] objectForKey:@"temperatureMax"];

    return cell;
}

希望对您有所帮助

Answer 3

您应该创建一个模型对象，例如WeatherObject class 并将您的响应解析为此类对象的数组。丢弃您在解析期间想要丢弃的任何字段。在您可以将 WeatherObject 中的 NSMutableArray 设置为您的 table 视图的数据源之后。这将是更加面向对象和人类可读的代码。
