我對編程任何類型的設備都很新穎,而且學習曲線陡峭,所以請原諒我,如果這樣做沒有太大意義,或者問題中的代碼很糟糕 - 我們都要開始某個地方,並且相信我,我已經閱讀並閱讀!iPhone - 按照字母順序創建桌面視圖
我從plist中創建一個表,這是一個字典數組 - 我需要這種格式,因爲後來我希望能夠更改一些值並將其寫回相關的plist'鍵'。 我希望有人能夠看到這一點,並給我一些指點至於如何...
- 從plist中,務必鍵/值「名」排序的數據表時尚A到Z的分組風格 - 這似乎是好的,但是,它會根據plist數組中字典的數量創建部分的數量,而某些字典應該在同一部分下組合在一起(請參閱以下)
- 根據plist中的項目將表格分成不同的部分。如果我有7個項目,跨越字母表,然後我想要7個部分。
- 在右側有一個索引,只有相關數量的條目 - 如果我沒有'Q'下的任何數據,那麼我不想'Q'顯示在索引中!
很明顯,我很長的一段路要將所有這些排除出去 - 代碼本身有點像'狗晚餐',因爲我一直在嘗試這麼多不同的事情,但沒有太多成功,所以如果你看到你不喜歡的東西請讓我知道!
我一直在試圖對所有相關的部分,如UILocalizedIndexedCollation和sortedArrayUsingDescriptors讀了,但我想我的大腦只是心不是到它...
任何及所有意見(除了「放棄你」對於這個'不夠光明',因爲我從不放棄任何我開始!')將不勝感激!
(有很多未使用的變量在開始時合成 - 爲了簡化我在這裏發佈的內容,代碼編譯沒有問題,並且給出了以下結果: a表格中有27個字母,右邊只標出了AJ的作品(這與表格中生成的部分數量相關 - 只有部分AJ,單元格的內容正是我想要的內容。)

任何意見,將不勝感激 - 目前我一直在這一個工作了一個星期沒有成功,接近放棄,我真的不想要做!
如果最糟糕的事情發生了,我不能完成這個任務,我會願意爲我寫這些功能,當然是一小筆費用!
乾杯,和繼承人希望...
