如何在Core Data中为二进制数据启用外部存储 [英] How to enable External Storage for Binary Data in Core Data

问题描述

我想使用iOS 5中的核心数据的新的外部二进制数据。我已经看过关于它的文章，例如： http://bluecrowbar.com/blog/2011/08/coredata-external.html

除了告诉您勾选[允许外部储存空间]方块以外，其他所有项目都不会显示如何启用。

我有一个实体设置了一些属性作为二进制数据，但我找不到任何地方的复选框。有人可以解释我能找到它吗？感谢

解决方案

确保您的属性设置为二进制数据类型，然后使用侧面板。

同时确保您使用Xcode 4.2

I would like to use the new External Binary Data for Core Data that came with iOS 5. I have had a look at articles about it such as: http://bluecrowbar.com/blog/2011/08/coredata-external.html

None of them actually show how to enable it other than telling you to check the box for "allow external storage".

I have an entity set up with some of its attributes as binary data but I can't find the checkbox anywhere. Could someone please explain where I can find it? Thanks

解决方案

Make sure your attribute is set to the type 'Binary Data' and then use the side panel.

Also make sure you are using Xcode 4.2
