Objective-C:从NSString提取子字符串的最佳方法? [英] Objective-C: Best way to extract substring from NSString?

问题描述

我有一个用空格分隔的字符串，例如@"abc xyz http://www.example.com aaa bbb ccc".

I have a space-separated string like @"abc xyz http://www.example.com aaa bbb ccc".

如何从中提取子字符串@"http://www.example.com"?

How can I extract the substring @"http://www.example.com" from it?

推荐答案

我知道这是一个很晚的答复，但是您可以使用以下代码获得子字符串"http://www.abc.com":

I know this is a very late reply, but you can get the substring "http://www.abc.com" with the following code:

[@"abc xyz http://www.abc.com aaa bbb ccc" substringWithRange:NSMakeRange(8, 18)]

当然，您仍然可以使用NSString.

Of course, you can still use an NSString for that.
