Compare two dates [duplicate]

Question

How can I compare two different dates to find out which is the later date? For example, in date1 I will store one date after downloading some data, and in date2, I will store the current date. Then I need to check which one is greater/later: something like if(date1>date2).

Answer 1

Something like:

    NSDate* timeNow = [NSDate date];

    // If less than 30 seconds, do something
    if ([timeNow timeIntervalSinceDate:anEarlierTime] < 30.0f)
    {
        // Do something
    }
