如何帖子和信息的时间转换为NSDate

如果执行requestForGrpahPath:@"me/inbox，然后就会这样：

"data": [
          {
            "id": "XXXXXXXXXXXXXXXXX",
            "from": {
              "name": "XXXXXXXXXXXX",
              "id": "XXXXXXXXXXXXXXX"
            },
            "message": "yeup!",
            "created_time": "2012-12-03T10:28:21+0000"   //将此时间转换为NSdate
          }, 

`

根据问题描述

NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy'-'MM'-'dd'T'HH:mm:ssZ"];
NSDate* date = [dateFormatter dateFromString:dateString];
