从网址字符串中获取最后一个'/'(斜杠)之后的所有字符 [英] Get all characters after the last '/' (slash) from url string

问题描述

如何从网址字符串中获取最后一个'/'(斜杠)之后的所有字符?

How to get all characters after the last '/' (slash) from url string?

在对某些站点进行Webview请求时，我从URL方案中收到了json字符串.例如:

I receive a json string from my URL scheme when making webview request for certain site. For example:

app://ga/ecommerce/％7B％22product％22:％22playstation4％22 ...}]

app://ga/ecommerce/%7B%22product%22:%22playstation4%22...}]

我想在最后'/'(斜杠)之后获取子字符串.

I would like to grab the substring after the last '/'(slash).

如何实现?我可以知道正则表达式的格式是什么吗?

How can I achieve it? May I know what is the format of Regex?

避免使用

NSRange lastDotRange = [sURL rangeOfString:@"/" options:NSBackwardsSearch];

因为我可能在json中转义了"/" .

because I might have escaped '/' in my json.

谢谢.
