If statement between two times of day

Question

What is the easiest way to have an if statement between two times? For example:

if ([timeisBetween=1:00 and 8:40]) {
    NSLog(@"Inside time period");
}
else {
    NSLog(@"Not in time period - after 8:30 in the morning")
}

and

if ([timeisBetween=22:00 and 5:40]) {
    NSLog(@"Inside time period 10:00 at night to 5:40 in the morning");
}
else {
    NSLog(@"Not in time period");
}

What have you tried so far? What data do you have and what is its type (`NSDate`, `NSTimeInterval`, `NSString`)? — rmaddy, Mar 17 '14 at 22:40
There are several ways to do it, but they all require actual programming, if you want a reasonably general solution. — Hot Licks, Mar 17 '14 at 22:50

Convert your NSStrings to NSDates via a NSDateFormatter and then compare them. Make sure your NSDate is between those ranges. These snippets will help point you in the right direction.

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    [formatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];

NSDate *startDate = [formatter dateFromString:@"2014-17-03 6:45:58"];
NSDate *endDate = [formatter dateFromString:@"2014-17-03 8:45:58"];

if ([startDate compare: endDate] == NSOrderedDescending) {
    NSLog(@"start is later than end");

} else if ([startDate compare:endDate] == NSOrderedAscending) {
    NSLog(@"start is earlier than end");

} else {
    NSLog(@"Same Dates");

}

Thanks for the answer. What do I do with times of everyday, rather than a set date?? Thanks, — Seb OH, Mar 19 '14 at 00:46
