在iOS + Swift中将音频转换为Base64字符串 [英] Convert Audio to Base64 string in iOS + Swift

问题描述

var fileLocation = NSString(string:NSBundle.mainBundle().pathForResource("test", ofType: "mp3")!)
let plainData = fileLocation(NSUTF8StringEncoding)
let base64String = plainData?.base64EncodedStringWithOptions(.allZeros)
println(base64String!)

推荐答案

您必须从文件位置获取NSData，在这里您丢失了该位置.检查以下代码:

You have to get NSData from the location of your file, which is you missing here. Check below code:

var error: NSError?

var fileLocation = NSString(string:NSBundle.mainBundle().pathForResource("test", ofType: "mp3")!)
let fileData = NSData(contentsOfFile: fileLocation, options: NSDataReadingOptions.DataReadingMappedIfSafe, error: &error)

let base64String = fileData?.base64EncodedStringWithOptions(.allZeros)
println(base64String!)

在这里您可以获取音频文件的NSData(无论文件格式是什么)，然后将这些数据转换为base64.

Here you can get NSData of audio file (whatever file format is) and then convert this data to base64.
