  You can't compare objects using == operator. There's a section on comparing NSDates in the docs: https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/nsdate_Class/Reference/Reference.html

  I think I understand what you're asking. You're trying to get a random display about the current date. I would recommend using a switch statement triggered off an arc4random value. Then from each case in the switch statement, use the NSDateFormatter to display the date with different outputs. here is an example for three different outputs:
  
  
NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
NSDate *today = [NSDate date];

int random = arc4random() % 3;

switch (random) {
case 0:
[dateFormatter setDateFormat:@"MMM dd"];
NSString *formattedDate = [dateFormatter stringFromDate:today];
NSLog(@"Hey, it's %@", formattedDate);
break;
case 1:
[dateFormatter setDateFormat:@"EEEE"];
formattedDate = [dateFormatter stringFromDate:today];
NSLog(@"What! It's %@", formattedDate);
break;
case 2:
[dateFormatter setDateFormat:@"dd"];
formattedDate = [dateFormatter stringFromDate:today];
NSLog(@"Today is lucky number %@", formattedDate);
break;
}

  
  You can add as many cases as you want. Like baja said, checkout the NSDate class reference to see how to use other formats.
