Verify the existence of a word in an NSString

cocoa, iphone, nsstring, objective-c

Solution

The following should work:

NSString *sentence = @"The quick brown fox";
NSString *word = @"quack";
if ([sentence rangeOfString:word].location != NSNotFound) {
    NSLog(@"Yes it does contain that word");
}

It uses `rangeOfString:` to return an `NSRange` structure, indicating the location of the word, if it can't find it `NSRange.location` will be equal to `NSNotFound`.

Problem

I searched a bit, but couldn't find an answer to this (probably very simple) question. I have an NSString, and I'd like to check if it contains a word. Something like this: ``` NSString *sentence = @"The quick brown fox"; NSString *word = @"quack"; if ([sentence containsWord:word]) { NSLog(@"Yes it does contain that word"); } ``` Thanks.
