How can i compare two dates?

Question

I am trying to compare two dates whether which one is the new or old, my dates are in following format:

2013-06-03 09:30:35

(YYYY-MM-DD HH:MM:SS)

Please give me some ideas, both are currently in string format?

So is that possible to convert ad check?

Convert that strings into NSDate using dateFormatter. You can check this link Here is good discussion of your problem How to compare two NSDates: Which is more recent?

If you think a question is a duplicate, please mark it is a duplicate rather than answering with a link to the other question and answer. – Abizern Jun 04 '13 at 10:17

It's under the link for closing. It gives you options for why you are recommending closure. One of the reasons is that it is a duplicate. You can paste the link to the duplicate in there. – Abizern Jun 04 '13 at 10:21

try this

NSString to NSDate

NSString *dateString = @"01-02-2010";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
// this is imporant - we set our input date format to match our input string
// if format doesn't match you'll get nil from your string, so be careful
[dateFormatter setDateFormat:@"dd-MM-yyyy"];
NSDate *dateFromString = [[NSDate alloc] init];
// voila!
dateFromString = [dateFormatter dateFromString:dateString];
[dateFormatter release];

NSDate convert to NSString:

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"dd-MM-yyyy"];
NSString *strDate = [dateFormatter stringFromDate:[NSDate date]];
NSLog(@"%@", strDate);
[dateFormatter release];

Please read this

enter link description here

if ([yourFirstDate compare:secondDate] == NSOrderedDescending) {
    NSLog(@"yourFirstDate is later than secondDate");        

} else if ([yourFirstDate compare:secondDate] == NSOrderedAscending) {
    NSLog(@"yourFirstDate is earlier than secondDate");

} else {
    NSLog(@"dates are the same");

}

same as @DIVYU 's Link

If it's the same as the duplicate link, then just mark the question as a duplicate. It's the way this site is supposed to work. Duplicate questions just make it harder to have proper answers to proper questions. – Abizern Jun 04 '13 at 10:33
