swift - Xcode Firebase I更新Firebase数据库值时遇到问题

当我运行程序并更改值并将其发送给Firebase时，出现错误：由于未捕获的异常'InvalidFirebaseData'而终止应用程序，原因：'（updateChildValues：withCompletionBlock :)无法在处存储UITextField类型的对象。只能存储NSNumber，NSString，NSDictionary和NSArray类型的对象。

func updateUsersProfile() {
    //check to see if the user is logged in
    if let userID = Auth.auth().currentUser?.uid {
        //create an access point the Firebase storage
        let storageItem = storageRef.child("profile_images").child(userID)
        //get the image uploaded from photo library
        guard let image = profileImageView.image else { return }
        if let newImage = image.pngData() {
            //upload to Firebase storage
            storageItem.putData(newImage, metadata: nil, completion: {
                (metadata, error) in
                if error != nil {
                    print(error!)
                    return
                }
                storageItem.downloadURL(completion: { (url, error) in
                    if error != nil {
                        print(error!)
                        return
                    }
                    if let profilePhotoURL = url?.absoluteString {
                        guard let newUserName = self.usernameText.text else { return }
                        guard let newDisplayName = self.displayNameText.text else { return }
                        guard let newBioText = self.bioText.text else { return }
                        guard let newDescription = self.descriptionText else { return }

                        let newValuesForProfile =
                            ["photo": profilePhotoURL,
                             "username": newUserName,
                             "displayname": newDisplayName,
                             "mydescription": newDescription,
                             "bio": newBioText]

                        //Update the Firebase database for that user
                        self.databaseRef.child("profile").child(userID).updateChildValues(newValuesForProfile, withCompletionBlock: { (error, ref) in
                            if error != nil {
                                print(error!)
                                return
                            }
                            print("Profile successfully updated")
                        })
                    }
                })
            })
        }
    }

最佳答案

错误：由于未捕获的异常'InvalidFirebaseData'而终止应用程序，原因：'（updateChildValues：withCompletionBlock :)无法将UITextField类型的对象存储在。只能存储NSNumber，NSString，NSDictionary和NSArray类型的对象。


错误指出函数updateChildValues:withCompletionBlock试图存储类型为UITextField的对象而不是文本。因此，您应该检查是否编写了某些文本字段而不是文本字段的文本。

通过检查，您发现您已将descriptionText添加到词典而不是文本中。将行更改为：

guard let newDescription = self.descriptionText.text else { return }
