使用NSString将UTF-8编码转换为ISO 8859-1编码 [英] Convert UTF-8 encoding to ISO 8859-1 encoding with NSString

问题描述

我有一个应用程序从服务器读取UTF-8格式的数据，但它必须显示在ISO 8859-1（拉丁语-1）。是否有任何Cocoa API来实现这一点？

I have an application that reads the data in UTF-8 format from the server, but it has to be displayed in ISO 8859-1(Latin-1). Are there any Cocoa APIs to achieve this?

推荐答案

可以使用 NSString 的 getCString：maxLength：encoding： 方法，如下所示：

You can use NSString's getCString:maxLength:encoding: method, like this:

char converted[([string length] + 1)];
[string getCString:converted maxLength:([string length] + 1) encoding: NSISOLatin1StringEncoding];

NSLog(@"%s", converted);

一旦你有了这个，你可以重新初始化一个 NSString 类方法：

Once you have this, you can then re-initialize an NSString instance from that same encoding using the stringWithCString:encoding: class method:

NSString *converted_str = [NSString stringWithCString:converted encoding:NSISOLatin1StringEncoding];
