Here is one way to do that:

NSDateComponents *components = [[[NSDateComponents alloc] init] autorelease];
[components setDay:-1];

NSDate *yesterday = [[NSCalendar currentCalendar] dateByAddingComponents:components toDate:[NSDate date] options:0];

Take a look at the Date and Time programming guide.

Doesn't subtract a negative number makes it adding 1 day? – honcheng Aug 26 '11 at 01:50

The method dateByAddingComponents *adds* – progrmr Aug 26 '11 at 02:40
I changed that variable name to just `components` instead of `componentsToSubtract` since we are actually *adding* here. – progrmr May 21 '14 at 18:48
