Case-insensitive iPhone strings

// Nsordereddescending determines the size of the two object values (which are compared alphabetically. astring02 is true if it is smaller than astring01)

// Compare string 2 without case sensitivity

// Nscaseinsensitivesearch: case-insensitive comparison nsliteralsearch: performs a full comparison. case-sensitive nsnumericsearch: compares the number of characters of a string, not the character value.
