类型没有成员名称'objectForKey'并使用未解析的标识符

使用swift / parse尝试在下表视图控制器中填充自定义单元格 . pfquery代码似乎没问题，但是当我尝试使用数据来填充cell.something.text以及应该返回的结果时，我收到错误，指示该类型没有名为'objectForKey'的成员并且使用未解决的标识符 . 这些错误特别发生在override func tableView（tableView..cellForRowAtIndexPath ....

    }



    func loadData(){
        timelineData.removeAllObjects()
        //let predicate = NSPredicate(format: PFuser = PFUser.current)
        var findTimelineData:PFQuery = PFQuery(className: "event")
