正确的编码为ID3标签iOS中 [英] Correct encoding for ID3 Tags in iOS

问题描述

我想从我的项目一堆MP3文件得到ID3标签。

I'm trying to get ID3 tags from a bunch of mp3 files in my project.

AudioFileGetProperty(audioFile, kAudioFilePropertyInfoDictionary, &size, &metadataDictionary);

如果标签不包含西里尔符号，输出看起来在设备上确定。不过我有时会收到类似这样的值：

If the tag doesn't contain cyrillic symbols, the output looks OK on the device. However I sometimes get values like this one:

album = "\U00ce\U00f2\U00ea\U00f0\U00fb\U00f2\U00ee\U00e5 \U00d0\U00e0\U00e4\U00e8\U00ee 102.5FM";
"approximate duration in seconds" = "260.623";

和它导致扭曲的符号显示（ http://d.pr/i/X9wG ）

and it leads to distorted symbols display (http://d.pr/i/X9wG).

有什么方法脱code这些符号成可读的形式？我已经试过

Is there any way to decode these symbols into a readable form? I've already tried

NSString* value = [metadataDictionary objectForKey: key];
NSData* data = [value dataUsingEncoding: NSASCIIStringEncoding];
NSString* string = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];

但结果保持不变。

but the result stays the same.

任何帮助将大大AP preciated！

Any help will be greatly appreciated!

[更新]

我倾向于尝试在这种SO回答，但是否有其他方法吗？

I tend to try a solution provided in this SO answer, but are there any other ways?

推荐答案

这是一种取消code这些符号成可读的形式：

That's way to decode these symbols into a readable form:

NSString *value = [metadataDictionary objectForKey:@"artist"];
const char *cString = [value cStringUsingEncoding:NSWindowsCP1252StringEncoding];
NSString *artist = [NSString stringWithCString:cString encoding:NSWindowsCP1251StringEncoding];
