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

Objective-C Language NSString Splitting If you need to split on a set of several different delimiters, use -[NSString componentsSeparatedByCharactersInSet:] . If you need to break a string into its individual characters, loop over the length of the string and convert each character into a new string.
You can split a String by whitespaces or tabs in Java by using the split() method of java. lang. String class. This method accepts a regular expression and you can pass a regex matching with whitespace to split the String where words are separated by spaces.
For those who are trying to remove space in the middle of a string, use [yourString stringByReplacingOccurrencesOfString:@" " withString:@""] .
Creating NSArray Objects Using Array Literals In addition to the provided initializers, such as initWithObjects: , you can create an NSArray object using an array literal. In Objective-C, the compiler generates code that makes an underlying call to the init(objects:count:) method.
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 != ''"]]; I'd suggest a two-step aproach:
NSArray *wordsAndEmptyStrings = [yourLongString componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceCharacterSet]]; NSArray *words = [wordsAndEmptyStrings filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"length > 0"]]; If you love us?
