$ b $核心数据支持二进制数据类型 - 当您使用二进制数据字段定义模型时，它将使用NSData字段创建模型类。您可以将图像移动到NSData字段，CoreData将为您保存。

然后可以使用UIImage initWithData：从NSData字段加载图像。 / p>

希望这有助于！

I want to store image for every employee while updating their records. How can I do that? I have a dictionary storing name, id and department of employees. Now i want the image to be saved together.

Please help

解决方案

Core Data supports the "Binary Data" type - When you define a model with a Binary Data field, it creates your model class with an NSData field. You can move an image into the NSData field, and CoreData will save it for you.

You can then use UIImage initWithData: to load the image from the NSData field.

Hope this helps !
