simplest way nscountedset:

nscountedset* stringset = [[nscountedset alloc] initwitharray:strings]; nsstring* mostcommon = nil; nsuinteger highestcount = 0;  for(nsstring* string in stringset) {     nsuinteger count = [stringset countforobject:string];     if(count > highestcount) {         highestcount = count;         mostcommon = string;     } }
