If statement with dates

Question

what I am trying to do is make a if statement with dates using greater than less than signs. For some reason only the greater than sign works. Here is my code:

Answer 1

create a NSDate object with the time 8:10 and one with 8:00. Now you can compare the given date with both these dates

if(([date0800 compare:date] == NSOrderingAscending) && [date0810 compare:date] == NSOrderingDescending) )
{
    // date is between the other
}

---

to create the boundaries dates you can do this

NSDate *date = [NSDate date]; // now
NSDateComponents *components = [[NSCalendar currentCalendar] components:( NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit ) fromDate:date];
components.hour = 8;
components.minute = 0;

NSDate *date0800 = [[NSCalendar currentCalendar] dateFromComponents: components];
components.minute = 10;
NSDate *date0810 = [[NSCalendar currentCalendar] dateFromComponents: components];

---

if you insist of using operators like < and >, you can use the timeinterval of the date objects.

if(([date0800 timeIntervalSince1970] < [date timeIntervalSince1970]) && ([date0810 timeIntervalSince1970] > [date timeIntervalSince1970]))
{
    // date lays between the other two
}

but beware of checking == on it, as it could be faulty due to rounding errors.
