Why can't NSDate be compared using < or>?

Question

NSDate *date = [NSDate date];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc]init];
[dateFormat setDateFormat:@\"MM/dd/yyyy\"];
NSLog([@\"today is \" stringBy         


        

Answer 1

in short: because basic operators only work on primitive types for any OBJECT < > != == ... does a basic operation on the POINTER value of this variable

in c++ those operators can be overwritten in objC and java and other languages you need to use the isEqual function of NSObject
