在NSString对象中查找子字符串 [英] Finding a substring in a NSString object

问题描述

我有一个NSString对象，我想通过定位一个单词从中创建一个子字符串.

I have an NSString object and I want to make a substring from it, by locating a word.

例如，我的字符串是:狗吃了猫"，我希望程序定位单词"ate"并创建一个子字符串，将其作为猫".

For example, my string is: "The dog ate the cat", I want the program to locate the word "ate" and make a substring that will be "the cat".

有人可以帮我还是给我一个例子?

Can someone help me out or give me an example?

谢谢

推荐答案

NSRange range = [string rangeOfString:@"ate"];
NSString *substring = [[string substringFromIndex:NSMaxRange(range)] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
