iOS Date Formatter Returns Null

Question

I have searched the internet for a solution but have not been able to solve my problem.

I have a date that I am formatting but it always returns null.

    NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.sss.ZZZZ"];
    NSString *dueDateString = [NSString stringWithFormat:@"2014-07-11T15:21:42.207+0200"];
    NSDate *dateFromApi = [dateFormatter dateFromString:dueDateString];
    [dateFormatter setDateFormat:@"yyyy/MM/dd"];
    NSString *finalDateString = [dateFormatter stringFromDate:dateFromApi];
    NSLog(@"dueDateString %@", dueDateString);
    NSLog(@"dateFromApi %@", dateFromApi);
    NSLog(@"finalDateString%@", finalDateString);

I do not know what I am doing wrong but the format above seems to work if I use this format 0001-01-03T00:00:00.000+0200 I get an output of 0001/01/02. As soon as it changes like this 2014-07-11T15:21:42.207+0200 it does not work and always returns null?
