Objective-C中的urldecode [英] urldecode in objective-c

问题描述

我正在处理Objective-C中的Urlencoded字符串.是否有实际上可以反转urlENCODING的基础函数?

I'm dealing with an urlencoded string in objective-c. Is there a foundation function that actually reverse the urlENCODING?

收到的字符串类似于:K％FChlschrank，但应在解码Kühlschrank之后

The string received is like: K%FChlschrank but should be after decoding Kühlschrank

推荐答案

Apple已弃用stringByReplacingPercentEscapesUsingEncoding: 从iOS9开始.请使用stringByRemovingPercentEncoding.

Apple has depreacted stringByReplacingPercentEscapesUsingEncoding: since iOS9. Please use stringByRemovingPercentEncoding.

新方法，通过将所有百分比编码的序列替换为匹配的UTF-8字符，返回由接收者生成的新字符串.

The new method, Returns a new string made from the receiver by replacing all percent-encoded sequences with the matching UTF-8 characters.

示例:

NSString *encodedLink = @"hello%20world";
NSString *decodedUrl = [encodedLink stringByRemovingPercentEncoding];
NSLog (@"%@", decodedUrl);

输出:

hello world
