NSDate *today = [NSDate date]; // it will give you current date
NSDate *newDate = [dateFormatter dateWithString:@"xxxxxx"]; // your date
NSComparisonResult result;
//has three possible values: NSOrderedSame,NSOrderedDescending, NSOrderedAscending
result = [today compare:newDate]; // comparing two dates
if(result==NSOrderedAscending)
NSLog(@"today is less");
else if(result==NSOrderedDescending)
NSLog(@"newDate is less");
else
NSLog(@"Both dates are same");
