我希望能够将图像和视频加载到我的UICollectionView。

这是我的解析查询代码:

var arrayOfDetails = [Details]()
func queryFromParse(){
        let query = PFQuery(className: "currentUploads")
        query.orderByDescending("createdAt")
        query.findObjectsInBackgroundWithBlock { (objects:[AnyObject]?, error:NSError?) -> Void in
            if error == nil
            {
                if let newObjects = objects as? [PFObject] {

                    for oneobject in newObjects {
                        let text = oneobject["imageText"] as! String
                        let username = oneobject["username"] as! String
                        let objID = oneobject.objectId!
                        let time = oneobject.createdAt!
                        let likedBy = oneobject["likedBy"] as! NSArray
                        let comments = oneobject["comments"] as! NSArray


                        if let userImage = oneobject["imageFile"] as? PFFile {
                            let userImage = oneobject["imageFile"] as! PFFile

                            let imageURL = userImage.url
                            let OneBigObject = Details(username: username, text: text, CreatedAt: time, image: imageURL!, objID: objID, likedBy: likedBy, comments: comments)

                            self.arrayOfDetails.append(OneBigObject)

                            dispatch_async(dispatch_get_main_queue()) { self.collectionView.reloadData() }
                        }
                    }
                }
            }
        }
    }

我的结构细节:

struct Details {
    var username:String!
    var text:String!
    var CreatedAt:NSDate!
    var image:String!
    var objID:String!
    var likedBy:NSArray
    var comments:NSArray
    init(username:String,text:String,CreatedAt:NSDate,image:String,objID:String,likedBy:NSArray,comments:NSArray){

        self.username = username
        self.text = text
        self.CreatedAt = CreatedAt
        self.image = image
        self.objID = objID
        self.likedBy = likedBy
        self.comments = comments
    }
}

在我的cellForItemAtIndexPath我使用let post = self.arrayOfDetails[indexPath.row]来获取当前对象,但我在这里遇到了一些问题。在解析中,我将图像存储为文件,名称为“uploaded_image.png”,视频存储为文件,名称为“uploaded_video.mp4”。如果文件是“uploaded_image.png”,如何在UICollectionViewCell中创建UIImageView,如果文件是“uploaded_video.mp4”,我如何在视频播放器中创建?

或其他任何建议?
