Discussion
As an example, the following code excerpt creates a set containing three different types of elements (assuming a exits):
NSSet *mySet;
NSData *someData = [NSData dataWithContentsOfFile:aPath];
NSValue *aValue = [NSNumber numberWithInteger:5];
NSString *aString = @"a string";
mySet = [NSSet setWithObjects:someData, aValue, aString, nil];
