Finding a substring in a NSString object

Question

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

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".

Can someone help me out or give me an example?

Thanks,

Answer 1

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

Answer 2

NSString *str = @"The dog ate the cat";
NSString *search = @"ate";
NSString *sub = [str substringFromIndex:NSMaxRange([str rangeOfString:search])];

If you want to trim whitespace you can do that separately.
