在NSData和base64字符串之间转换 [英] Converting between NSData and base64 strings

问题描述

在 NSData 和base64字符串之间进行转换的最简单，最快的代码是什么？我已经在SO上阅读了大量的解决方案，而且大多数都涉及添加另一个类等。我找到了一个很好的解决方案这里但它太复杂了。

What is the easiest and fastest code to do a conversion between NSData and a base64 string? I've read a bunch of solutions at SO and mostly they involve in adding another class etc. I found a great solution here but it's too complex.

推荐答案

向下滚动到结论您链接的页面部分 >并下载提供的NSData + Base64文件。它是迄今为止我见过的最好的解决方案，非常容易使用。如果您可以了解有关Cocoa的任何信息，您可以学习使用该项目。

Scroll down to the Conclusion section on the page you linked and download the provided NSData+Base64 files. Its the best solution I have seen so far and is incredibly easy to use. If you can learn anything about Cocoa, you can learn to use that project.

示例

NSString *originalString = [NSString stringWithFormat:@"test"]; 
NSData *data = [NSData dataFromBase64String:originalString];  
NSLog([data base64EncodedString]); 

以上将在将原始字符串转换为base64并返回正常的未编码字符串后打印出来。

The above will print out the original string after converting it to base64 and back to a normal unencoded string.
