How to find that current date is from a Odd or Even week in Objective C?

Question

I have to validate, questions on the basis of the odd or even week. If there is odd week then I will have to show different questions from even week. I am getting the questions from server from a "GET" method.

try this

NSCalendar *calendar = [NSCalendar currentCalendar];
 NSDateComponents *dateComponent = [calendar components:(NSWeekOfYearCalendarUnit) fromDate:[NSDate date]];
 NSLog(@"%lu",(long unsigned)dateComponent.weekOfYear);

bool isEven = (dateComponent.weekOfYear % 2) == 0

`BOOL isEven = (dateComponent.weekOfYear & 1) == 0;`. Original code from this [answer](http://stackoverflow.com/a/17587863/299924). Note: your code will crash. – trojanfoe Mar 03 '16 at 13:38
Do you know what `NSLog(@"%@", ...)` does? – trojanfoe Mar 03 '16 at 13:41
