Question

i have and function that convert string to date. and its working very fine but when i try to convert 20130331 the application crashs.
and here my code

NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"yyyyMMdd"];
NSDate *date = [dateFormat dateFromString:dateStr];
NSLog(@"before %@ dateStr %@",date,dateStr);

the log is is following

2013-01-02 17:56:04.402 jana2ez[6067:11303] before 2013-03-28 22:00:00 +0000 dateStr 20130329 
2013-01-02 17:56:04.498 jana2ez[6067:11303] before 2013-03-29 22:00:00 +0000 dateStr 20130330 
2013-01-02 17:56:04.626 jana2ez[6067:11303] before (null) dateStr 20130331

any idea??

After hours of bad results, finally I found a solution inspired from @Echihl’s comment.

I changed the time in the date so the date will be parsed to same date found in dateStr.

    NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
    [dateFormat setDateFormat:@"yyyyMMdd HHmm"];
    NSDate *date = [dateFormat dateFromString:dateStr];
    NSLog(@"before %@ dateStr %@",date,dateStr);

My output becomes

    before 2013-03-31 05:00:00 +0000 dateStr 20130331 0800

Previously 20130329 was parsed to March 28th, 2013, at 10 PM
