Cannot find the right date format (NSDateFormatter) for this

问题

I cannot convert this kind of strings to NSDate, please help me out here. What am I doing wrong below?

dateString = @"201302051614461";
NSDateFormatter *dateFormatter = [NSDateFormatter new];
[dateFormatter setDateFormat:@"YYYYMMddHHmmSSSSS"];
NSDate *date = [dateFormatter dateFromString:dateString];
NSLog(@"dateString: %@", dateString);
NSLog(@"date: %@", date);  

This returns with an empty date.

回答1:

If I break it like this 2013 02 05 16 14 46 1
Then the format string is @"yyyyMMddHHmmssS

回答2:

@"yyyyMMddHHmmssS" -- YYYY will give you the wrong year in many cases, and capitol S is for fractional seconds.
