在iOS中是否有用于写入plist的视频? [英] is there a Video for writing to plist in iOS?

问题描述

我并不是说我很懒(我是)，但我想阅读plist中的内容，然后在用户执行某项操作时，将该信息附加到现有的plist中，然后再写回去，这样信息就不会丢失.

I'm not saying I'm lazy (I am), but I want to read what is in the plist, and then when the user does something, to append that info to the existing plist, and write it back, so that info is not lost.

现在这就是我想播放的视频的类型.

Now that's the type of thing I would think there'd be a video on.

因此，我的问题是双重的:

Thus, my question is twofold:

a)关于使用文件处理程序写入plist的好视频(iTunes，Standford Univ，iOS应用程序编程指南)在哪里? b)如何进行搜索并将媒体限制为视频(以便将来可以找到有关这些主题的视频)? 我特别在寻找如何处理臭名昭著的第一次，以及如何通过错误地认为自己是空的来确保我不会覆盖良好的数据.

a) Where's a good video (iTunes, Standford Univ, iOS App Pgming Guide) on writing to a plist using file handlers ?(gulp) b) how can I do a search and restrict the media to videos (so I can find videos on these subjects in the future)? I'm especially looking for how to handle the notorious first time, and how to make sure I don't overwrite good data by wrongly thinking it's empty.
