Question

如何检查字段中的值并达到不同的目的。

如图所示，如果VIP值为0，则显示"VIP"；无法前往"；

检查VIP值是否为1，然后转到查看

我该怎么做才能实现

这是我当前的代码

let UID = Auth.auth().currentUser?.uid
let db = Firestore.firestore()
let docRef = db.collection("Users").document(UID!)

docRef.getDocument { (document, error) in
if error != nil {


self.showMsg(message: "no")

}else{
let array = document!.get("vip") as! String
switch array {
case "0":
self.showMsg(message: "0")
case "1":
self.showMsg(message: "1")

default:
print("the other city")
}
}
}
}

let UID = Auth.auth().currentUser?.uid
let db = Firestore.firestore()
let docRef = db.collection("Users").document(UID!)
docRef.getDocument { (document, error) in
if error == error {
print ("Error Occurs")
} else {
let array = document.data["vip"] as! String
switch array {
case "0":
self.showMsg(message: "0")
case "1":
self.showMsg(message: "1")

default:
print("the other city")
}
}
}
}
