Ios 使用Swift中的解析创建具有配置文件图片的用户

如何使用Parse创建注册页面，让用户在Swift中输入自己的个人资料图片。

请检查下面的代码，使用Parse.com将照片字段添加到用户表中

 var user = PFUser()

    let imageData = UIImageJPEGRepresentation(userDetails.getPhoto(), 0.05)
    let imageFile = PFFile(name:"image.jpg", data:imageData)
    imageFile.save()

    user.username = usrEntered
    user.password = pwdEntered
    user.email = emlEntered

    user.setObject(imageFile, forKey: "photo")

    user.signUpInBackgroundWithBlock {
        (succeeded: Bool!, error: NSError!) -> Void in
            if error == nil {
               // Hooray! Let them use the app now.
               self.messageLabel.text = "User Signed Up";
            } else {
                // Show the errorString somewhere and let the user try again.
            }
    }
