dateFromString give error when string is 20130331

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

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

NSCalendar* gregCalendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
[dateFormat setCalendar:gregCalendar];
