迅速。从对象内获取对象

Question

如何从对象内部访问对象：

 public List<Tasks> multipleFilter(String PriorityFilter,String startDateFilter,String endDateFilter,List<Tasks> listAllTasks)
{
    List<Tasks> listTasksAfterFiltering = new ArrayList<>();
    for(Tasks task_obj : listAllTasks)
    {
        String PriorityTask = task_obj.getPriority();
        String startDateTask = task_obj.getStartDate();
        String endDateTask = task_obj.getEndDate();

        if(PriorityFilter.equals(PriorityTask) || PriorityFilter.isEmpty())
            if(startDateFilter.equals(startDateTask) || startDateFilter.isEmpty())
                if(endDateFilter.equals(endDateTask) || endDateFilter.isEmpty())
                    if(!PriorityFilter.isEmpty() || !startDateFilter.isEmpty() || !endDateFilter.isEmpty()){
                        listTasksAfterFiltering.add(task_obj);
                    }
    }

    return listTasksAfterFiltering;

}

Answer 1

我认为您想要的是let test = Array(marketDailyData.timeSeriesDaily.values)[0]

Answer 2

错误消息对此进行了解释：TimeSeriesDaily是由String而不是int键入的字典

试试

let test = marketDailyData.timeSeriesDaily["2019-01-28"]
