Checking if one NSDate is greater than another

Question

if (datStartDate > datEndDate) {

This doesn't seem to work. I know there's a isEqual, etc., but how do I perform "is greater than"?

There are both NSDate.

Answer 1

The easiest method i'm aware is:

if( [firstDate timeIntervalSinceDate:secondDate] > 0 ) {

The other answers cover compare:, wanted to add some flavour ;).

Answer 2

To compare dates use -compare: method:

Return Value If:

• The receiver and anotherDate are exactly equal to each other, NSOrderedSame
• The receiver is later in time than anotherDate, NSOrderedDescending
• The receiver is earlier in time than anotherDate, NSOrderedAscending.
