How to separate string by space using Objective-C?

Question

Assume that I have a String like this:

hello world       this may     have lots   of sp:ace or little      space 

I would like to seperate this String to this:

@"hello", @"world", @"this", @"may", @"have", @"lots", @"of", @"sp:ace", @"or", @"little", @"space" 

Thank you.

Answer 1

NSString *aString = @"hello world       this may     have lots   of sp:ace or little      space"; NSArray *array = [aString componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceCharacterSet]]; array = [array filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"SELF != ''"]]; 

Answer 2

I'd suggest a two-step aproach:

NSArray *wordsAndEmptyStrings = [yourLongString componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceCharacterSet]]; NSArray *words = [wordsAndEmptyStrings filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"length > 0"]];
