iPhone：在Core Data中存储视频和音频？ [英] iPhone: Storing video and audio in Core Data?
问题描述
我需要为使用Core Data的现有应用程式新增影片和音讯录音功能。我一直在想我应该将它们保存到文件系统，并使用Core Data引用它们，但我想知道我是否可以将它们放入Core Data作为Transformable属性，并忽略文件系统？
I need to add video and audio recording functionality to an existing app that uses Core Data. I've been thinking that I should save them to the file system and reference them using Core Data but I wondered if I can put them into Core Data as Transformable attributes and ignore the file system altogether?
我的直觉是，这是一个真正的坏主意™。我喜欢使用核心数据的轻松和增值。但我试图搜索iphone核心数据视频，但只是返回堆的核心数据教程。
My gut feeling is that this is a Really Bad Idea™. I do like the ease and value-add of using Core Data however.. I've tried searching for 'iphone core data video' but that just returns heaps of core data tutorials.
推荐答案
当使用coredata保存二进制数据时，Coredata有一个允许外部存储选项，将自动存储大于1mb的文件磁盘。
Coredata has a 'allow external storage' option when saving binary data with coredata which will automatically store files larger than 1mb to the disk.
但是，此问题与以下问题非常相似：
However, this question is very similar to these questions:
Storing large (e.g. image/movie) files in Core Data on the iPhone
与所选择的答案，Core Data应该能够保持良好的性能，只要没有大量的视频或照片。
In contrast to the selected answer, Core Data should be able to maintain good performance as long as there isn't a huge amount of videos or photos.
