How to count words within a text string?

Question

On iOS, how can I count words within a specific text string?

Answer 1

One liner accurate solution:

return [[self componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"length > 0"]].count;

This solution handles consecutive spaces correctly.
