我正在从Parse中检索一组图像,使用以下代码使用Swift.

var imageResources : Array<UIImage> = []
override func viewDidLoad(){
    super.viewDidLoad()
    self.loadImages()
}

func loadImages(){

    var query = PFQuery(className: "Images")
    query.orderByDescending("objectId")

    query.findObjectsInBackgroundWithBlock ({(objects:[AnyObject]!, error: NSError!) in
        if(error == nil){            

            for object : PFObject! in objects as [PFObject] {

                   if (error == nil) {
                        let image : UIImage = UIImage(data:imageData)
                        //image object implementation
                        self.imageResources.append(image)
                    }

                })//getDataInBackgroundWithBlock - end

            }//for - end

        }
        else{
            println("Error …
