PF文件？不可转换为 'StringLiteralConvertible' 'AnyObject' 不可转换为 'String'

Question

我刚刚更新：

xcodeVersion 6.3 (6D570)

Swift 1.2 昨晚把我的话搞砸了，显然他们在 Swift 或 Parse 中做了一些更改。

我很困惑，我只是不知道如何解决这个问题...需要帮助。如果其他人遇到过相同的情况并已修复，请帮助我。

import UIKit
import Parse

class ProfileViewController: UIViewController, UITextFieldDelegate, UINavigationControllerDelegate, UIImagePickerControllerDelegate {

    // MARK: Variables declaration
    @IBOutlet weak var uploadPhotoBtn: UIButton!
    @IBOutlet weak var profilePhotoImageView: UIImageView!
    @IBOutlet var welcomeMessageLabel: UIView!
    @IBOutlet weak var greetings: UILabel!

    var imagePicker = UIImagePickerController()
    var existingImage : UIImage?
    var user = PFUser.currentUser()




    // The view has loaded this is the function that will be run at first before anything else
    override func viewDidLoad() {
        super.viewDidLoad()

        // MARK: make a circle image
        profilePhotoImageView.layer.cornerRadius = profilePhotoImageView.frame.size.width/2
        profilePhotoImageView.clipsToBounds = true

        //show my status 
        var mood = self.user["status"] as! String //=> 'AnyObject' is not convertible to 'String'

        self.greetings.text? = ( "\(mood)" )

        //get image if existing
        self.user[ "avatar" ] as? PFFile //=> 'PFFile? is not convertible to 'StringLiteralConvertible'

        if let userImageFile = self.user["avatar"] as? PFFile {PFFile? is not convertible to 'StringLiteralConvertible'

            userImageFile.getDataInBackgroundWithBlock({ (imageData:NSData!, error: NSError!) -> Void in

                if error == nil {

                    self.existingImage = UIImage(data: imageData)
                    self.profilePhotoImageView.image = self.existingImage
                }else {

                    let alert = UIAlertView(title: "Oops!", message: "Unable to get your profile photo", delegate: self, cancelButtonTitle: "Ok!")
                    alert.show()

                }
            })
        }

Answer 1

通过反复试验.. 这对我有用 Parse 1.7.1 和 Swift 1.2

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath, object: PFObject?) -> PFTableViewCell?

对象？["bax"]作为？细绳对象？["abc"] 作为！ PF文件？ -> 但是我的图像现在没有显示...仍在尝试解决它。

Answer 2

PFUser.CurrentUser returns 可选值，如果您确定，您的用户已登录并创建了 PFSession，那么试试这个：

var user = PFUser.currentUser()!

如果这不能解决问题，请告诉我。
