发送带有“正文请求”的NSMutableURLRequest请求在iOS中

我目前正在使用Google日历API并允许用户向与会者发布活动，但现在我应该发送一个POST方法，其中包含“请求正文” 。发送带有“正文请求”的NSMutableURLRequest请求在iOS中

下面是我应该发送请求：

https://www.googleapis.com/calendar/v3/calendars/<MyCalendorID>/events/<MyEventID> 

Request Body : 

{ 
"end": { 
    "date": "2015-05-19" 
}, 
"start": { 
    "date": "2015-05-20" 
}, 
"attendees": [ 
    { 
    "email": "[email protected]" 
    } 
] 
}

我敢肯定，我做错了什么在[request setHTTPBody]但是这是我能想到的唯一的事情。

请帮
