问题描述

我有疑问

private var query = PFQuery(className: "Ideas")
query.orderByDescending("createdAt")
query.findObjectsInBackgroundWithBlock { (data: [AnyObject]?, error) -> Void in
    var objects = data as! [PFObject]
    for tmp in objects {
        self.ideas.insert(CIdea(parseObject: tmp), atIndex: 0)
    }
}

我尝试从后台获取PFObject数组，从其实例获取CIdea并插入CIdea数组，但是遇到了在

I try to get array of PFObject from background, instance from it CIdea and insert in CIdea array, but got issue that found nil in

var objects = data as! [PFObject]

推荐答案

if let objects = Object as? [PFObject]{
        for tmp in objects {
        self.ideas.insert(CIdea(parseObject: tmp), atIndex: 0)
    }
 }
