Use the -isEqualToString  method to compare the value of two strings  Using the C    operator will simply compare the addresses of the objects   if   category isEqualToString   Some String             Do stuff

You can use case-sensitive or case-insensitive comparison  depending what you need  Case-sensitive is like this   if   category isEqualToString   Some String            Both strings are equal without respect to their case      Case-insensitive is like this   if   category compare   Some String  options NSCaseInsensitiveSearch     NSOrderedSame          Both strings are equal with respect to their case
