Ios PFO对象未保存在数据库中

我试图在Items类中保存一个项目，在images类中保存几个图像。在此之后，我想在项目中的列图片之间创建一个关系，并指向我刚才添加的图像。我尝试了以下内容，但它没有添加任何内容。似乎没有调用saveInBackgroundBlock

@IBAction func addToServer(sender: UIBarButtonItem) {


    var imageCell: ImageViewCell = tableView?.cellForRowAtIndexPath(NSIndexPath(forRow: 1, inSection: 0)) as ImageViewCell
    var adressCell: AdressViewCell = tableView?.cellForRowAtIndexPath(NSIndexPath(forRow: 0, inSection: 0)) as AdressViewCell
    var contentCell: ContentViewCell = tableView?.cellForRowAtIndexPath(NSIndexPath(forRow: 2, inSection: 0)) as ContentViewCell



    if imagePicked?.count > 0 && adressCell.adressField.text.length() > 0 && contentCell.priceField.text.length() > 0 && contentCell.contentField.text.length() > 0 && catBool == true {


        var address = adressCell.adressField.text + ", Denmark"



        var geocoder = CLGeocoder()
        geocoder.geocodeAddressString(address, {(placemarks: [AnyObject]!, error: NSError!) -> Void in


            if let placemark = placemarks?[0] as? CLPlacemark {

                var price = contentCell.priceField.text.toInt()
                var categoryObject: PFObject = self.objectArray?.objectAtIndex(self.currentIndex!) as PFObject

                var itemObject:PFObject = PFObject(className: "Items")
                let coordinates = placemark.location.coordinate as CLLocationCoordinate2D
                let geoPoint = PFGeoPoint(latitude: coordinates.latitude, longitude: coordinates.longitude)
                itemObject.setObject(geoPoint, forKey: "location")
                itemObject.setObject(contentCell.contentField.text, forKey: "description")
                itemObject.setObject(price, forKey: "price")
                itemObject.setObject(categoryObject, forKey: "category")



                var relation:PFRelation = itemObject.relationForKey("pictures")


                for var i = 0; i < self.imagePicked?.count; i++ {

                var image:UIImage = self.imagePicked?.objectAtIndex(i) as UIImage

                    var imageObject = PFObject(className: "Images")

                    var imageData:NSData = UIImageJPEGRepresentation(image, 1.0)
                    var theFile = PFFile(data: imageData)
                    imageObject.setObject(theFile, forKey: "image")



                    imageObject.saveInBackgroundWithBlock {
                        (success: Bool!, error: NSError!) -> Void in
                        println("lol1")
                        if (success != nil) {
                            relation.addObject(imageObject)
                            itemObject.saveInBackground()

                        }
                    }

                }





            }

        })



    } else {
        println("Please fill in all informations")
    }
}

你试过设置断点并验证它是否被调用了吗？没有，但是因为printlnlol1没有被调用，我猜它没有被调用。那么你应该进行一些调试并确定该行是否被调用。缺少的打印文本表示未执行闭包，因此可能也未调用save方法。在循环中设置断点，如果它从未停止，请尝试使用外部断点，等等。代码不起作用可能有几个原因，因此首先尝试缩小范围，直到找到可以说是这一行代码的内容。没有这一点，很难找出问题所在。
