如何在iPhone中的SQLite中一次插入多行？

在我的SQLite数据库中，只有一行效果，但我希望一次有4行效果。我的代码只适用于一行，不适用于其他值保存。如何编写在SQLite中保存多行的代码

我为天气创建应用程序。我通过XML解析获得所有天气状况信息，我解析表视图中的所有值，我看到所有值。这是完全正确的

在XML文件中，我得到了current condition元素和三个forecast condition，它表示当前条件，它显示今天的天气条件，forecast condition显示未来三天的天气条件。我创建了一个名为currentcondition和forecastcondition的类来获取这个数据

在forecastcondition元素中，我拥有与下一个3天相同的名称元素名称表示元素名称相同forecastcondition我将所有预测条件值存储在数组中，以便逐个获取下一个3天值，并在表格单元格中显示其正常工作。我在1单元格中看到当前条件值，在下一个3单元格中看到所有下一个3 ForecastCondition显示我的代码正常工作，但现在我想在sqlite数据库表中一次存储第一个单元格值和下一个3天值单元格，但我如何存储

但我将currentcondition保存在SQLite中，因为我创建了currentcondition类的对象，然后将值传递给SQLite。那么，如何同时解析另一个单元格值呢？我的表是一个，我在附件中给出了所有列名；我只想在此表列中插入值

我为store SQLite编写此代码，请检查代码。这是我的控制器类，在这里我在单元格上显示值，只有我为SQLite编写代码来保存数据
