我对任何类型的设备都非常陌生,并且处于陡峭的学习曲线上,所以如果这没有太多意义或问题中的代码很糟糕,请原谅我 - 我们都必须从某个地方开始,相信我,我读过读过读过!

我正在从一个字典数组的 plist 创建一个表 - 我需要这种格式的表格,因为稍后我希望能够更改一些值并写回相关的 plist 'key'。我希望有人能够看到这个并给我一些关于如何...

  1. 使表格以分组样式以 A 到 Z 的方式对 plist 中的键/值“名称”下的数据进行排序 - 这似乎没问题,但是,它会根据plist 中的数组,而某些字典应组合在同一部分下(见下文)
  2. 根据 plist 中的项目将表格分成几个部分,即。如果我有 7 个项目,跨越字母表,那么我想要 7 个部分。
  3. 在右侧有一个索引,只有相关数量的条目 - 如果我在“Q”下没有任何数据,那么我不希望“Q”显示在索引中!

显然,我距离整理所有这些还有很长的路要走 - 代码本身现在有点像“狗晚餐”,因为我一直在尝试很多不同的事情但没有取得多大成功,所以如果你看到一些你不喜欢的东西请告诉我!

我一直在尝试阅读所有相关部分,例如 UILocalizedIndexedCollat​​ion 和 sortedArrayUsingDescriptors,但我想我的大脑无法满足它......

任何和所有的建议(除了'放弃它你不够聪明'因为我从不放弃我开始的任何事情!)将不胜感激!

(在开始时合成了许多未使用的变量 - 为了简化我在此处发布的内容,我删除了相关代码,代码编译没有问题,并且工作给了我以下结果:索引 27 个字母的表在右侧只有 AJ 起作用(这与表中生成的部分数量相关 - 只有 AJ 部分。单元格的内容正是我想要的。)

任何建议都将不胜感激 - 目前我已经为此工作了大约一个星期,但没有成功,几乎要放弃了,我真的不想这样做!

如果最坏的情况发生在最坏的情况下并且我无法完成这项工作,是否有人愿意为我编写功能,当然需要支付少量费用!

干杯,希望...
