问题描述
我正在尝试解决,如何将 UIPicker ID 保存在 firebase 中。
我的目标是将部门 ID 与导师 ID 相关联,所以我的部门名称保存到 firbase 作为 nood
我对 UIPckier 视图的观察者:
@objc func ObserveDepartmentFromDatabase () {
APIs.Department_APIs.OberveDepartment { (dep) in
self.DepartmentContiner.append(dep)
}
}
@IBAction func SignUp(_ sender: Any) {
Auth.auth().createuser(withEmail: Email.text!,password: Password.text!) { (user,error) in
if error != nil{
print(error?.localizedDescription as Any)
return
} else {
print("user auth successfully")
guard let userID = Auth.auth().currentUser?.uid else {
return
}
// storge Image
let storge : StorageReference!
storge = Storage.storage().reference(withPath: "gs://uquaac-f7b71.appspot.com ").child("Profile_Images").child(userID)
if let profileImage = self.userSelectimageToStorage,let ProfileIMG = profileImage.jpegData(compressionQuality: 0.1){
storge.putData(ProfileIMG,Metadata: nil) { (MetaData,error) in
if error != nil {
print(error?.localizedDescription as Any)
return
}else{
storge.downloadURL { (url: URL?,error: Error?) in
let profileURL = url?.absoluteString
// save DataBase
let ref : DatabaseReference!
ref = Database.database().reference()
let userRef = ref.child("StudentAndTutor")
let newUserREF = userRef.child(userID)
newUserREF.setValue(["name" : self.Name.text,"email" : self.Email.text,"phoneNumber" : self.PhoneNumber.text,"department" : self.Department.text,"password" : self.Password.text,"profilImage" : profileURL,"userType" : self.userType.text]) { (error,ref) in
if error != nil {
print(error?.localizedDescription)
}
let linkeDepartmentWithTutor = Database.database().reference().child("linkeDepartmentWithTutorID")
linkeDepartmentWithTutor.child(self.Department.text!).child(userID).setValue(true) { (error,ref) in
if error != nil {
print(error?.localizedDescription)
}
}
}
let storyboard = UIStoryboard(name: "Main",bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "TabBar")
vc.modalPresentationStyle = .overFullScreen
self.present(vc,animated: true)
}
}
}
}
}
}
}
红线是指 UI 部门键,但在“LinkeDepartmentWithTutorID”中它不显示 ID 它只显示字符串所以我需要知道如何观察当前部门 ID 并将其链接到导师 ID
