objective c - how to find out is a long string contatins a word obj c, iphone -

-

i have long string has running list of "words entered" in text box. want able check long string against 1 word string see if long string contains word in short string.

any ideas?

i've tried , few other things, newstring long string , currenttextrightnow short string. 

textrange =[newstring rangeofstring:currenttextrightnow]; nslog(@"currenttextright %@", currenttextrightnow); if(textrange.location != nsnotfound)  {      nslog(@"does contatin substring");  }

i had same problem did. doing right (if textrange of type nsrange) problem nsnotfound doesn't work expected (might bug). instead can do

if (range.length > 0) {     //it found } else {     // didn't find }

hope helps.
