搜索NSString Cocoa？ [英] Searching NSString Cocoa?

问题描述

我有一个字母串，我想搜索一个特定的字母。

I have a string of letters and I want to search it for a specific letter.

NSString *word = @"word";

如何知道字符串是否包含字母w？

How would I find out if the string contained a letter "w"?

推荐答案

您可以使用rangeOfString：

You could do it using rangeOfString:

NSString *word = @"word";
if ([word rangeOfString:@"w"].location == NSNotFound)
    NSLog(@"word does not contain w");
else
    NSLog(@"word contains w");
