PFFile 到 UIImage swift 3？

Question

我正在尝试使用此代码

if let userPicture = object.valueForKey("Image")! as! PFFile {
   userPicture.getDataInBackgroundWithBlock({
      (imageData: Data!, error: Error!) -> Void in
         if (error == nil) {
            let image = UIImage(data:imageData)
            self.ImageArray.append(image)
         }
      })
}

我遇到了这个错误

Cannot convert value of type '(Data!, Error!) -> Void' to expected argument type 'PFDataResultBlock?'

我解决了我的问题

Swift 3 :

if let userPicture = object.valueForKey("Image")! as! PFFile {
userPicture.getDataInBackground({ (imageData: Data?, error: Error?) -> Void in
let image = UIImage(data: imageData!)
if image != nil {
self.imageArray.append(image!)
 }
 })
}
