如何连接code的NSData为base64？ （iPhone / iPad的） [英] How to encode NSData as base64? (iPhone/iPad)

问题描述

我想要一个UIImage添加到 HTML 电子邮件，但我有一个问题。我在很多其他职位环顾四周，他们说我需要我的的NSData 到的base64转换，但是所有州他们都建议方法似乎不存在了（除非我失去了一些东西？！）。

I'm trying to add a UIImage to an HTML email, however I'm having an issue. I have looked around at lots of other posts and they all state that I need to convert my NSData to base64, however the method they all suggest doesn't seem to exist anymore (unless I'm missing something?!).

下面是code我到目前为止有：

Here is the code I have so far:

UIImage *mapImage = [mapViewController convertMapToImage];
NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(mapImage)];
NSString *base64String = // [imageData base64EncodedString];   --- this method isn't recognised

请有人可以帮我吗？

推荐答案

您要使用没有按附带默认框架的方法。您可以在 NSData的类别添加到项目中。

The method you are trying to use doesn come with default framework. You can add the NSData category to your project.
