NSMutableDictonary为接下来7天的每一天的NSMutableArrays任务
我有一个应用程序，最终目标是允许用户输入他们的所有任务。有两种类型的任务：
•严格的任务 - 任务w。严格的开始时间
•随机任务 - 任务w。没有特定的开始时间
最终目标是应用程序将通过显示一周中接下来7天的分段表视图自动输出所有任务。该应用程序还需要适应＆＃34;你的＆＃34;随机任务＆＃34;进入你的日程表中的空白。
到目前为止，我得到了：
•任务成功保存到SQLite中
•一个抓住＆＃34;严格任务＆＃34;按时间顺序（最快）
•一种抓取所有＆＃34;随机任务＆＃34;的功能
•我认为这个功能可以成功排序并且适合＆＃34;将所有给定的任务放入已排序的最终数组中。
我有点难过的是如何以理想的方式为分段的tableview输出任务（我猜测标准方式是通过NSMutableArrays的NSMutableDictionary为接下来的7天每一天），但我不知道是什么从上面的项目符号排序的最终数组到NSMutableArrays的NSMutableDictionary的最佳方法.Anyone有一个建议吗？如果我觉得这比你需要的更困难，请随意仔细检查我的任何步骤。
