从 firebase 存储 SWIFT 中检索照片

Question

I have a problem since yesterday morning but I can't figure it out how can I resolve this issue.

I'm having a table view which is using prototype cells, 2 labels and 1 photo. For the labels I used Firestore and for the picture firebase storage.

The problems is that the only way I know how to retrieve photos from my firebase storage is this code

 
        let storage = Storage.storage()
        let storageRef = storage.reference()
        let ref = storageRef.child("Mancare/Mancare3.jpg")
        testImage.sd_setImage(with: ref)

I want to retrieve the photos into my table view, but I do not know how can I can accomplish that.

This is what im using for retrieving the labels with Firestore. I'll paste only the necessary parts of the code:

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return labels.count
    }


 func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableViewTest.dequeueReusableCell(withIdentifier: "CountryTableViewCell", for: indexPath) as! CountryTableViewCell
        let storage = Storage.storage()
        let storageRef = storage.reference()
        let ref = storageRef.child("Mancare/Mancare3.jpg")
        
        let label = labels[indexPath.row]
        cell.labelTest.text = label.firstLabel
        cell.labelLaba.text = label.secondLabel
      
        
        
        return cell
        
        
    }

func getDatabaseRecords() {
        
        let db = Firestore.firestore()
        labels = []  //  Empty the array
        db.collection("labels").getDocuments { (snapshot, error) in
            if let error = error {
                print(error)
                return
            } else {
                for document in snapshot!.documents {
                    let data = document.data()
                    let newEntry = Labels(
                        firstLabel: data["firstLabel"] as! String,
                        secondLabel: data["secondLabel"] as! String)
                        
                        
                        
                    self.labels
                        .append(newEntry)
                }
            }
            DispatchQueue.main.async {
                self.tableViewTest.reloadData()
            }
        }
    }

This is how I declared the labels:

struct Labels {
    let firstLabel: String
    let secondLabel: String
   
  
}

 var labels: [Labels] = []

If someone can help me, ill be forever grateful. Thanks

1. First, you need to fix your model so it can help you. Add the bucket name to the model like this:

Struct Labels {
    let firstLabel: String
    let secondLabel: String
    let photoKey: String // This will store the bucket name for this `Labels`
} 

2. Now in your getDatabaseRecords change:

let newEntry = Labels(firstLabel: data["firstLabel"] as! String,
                      secondLabel: data["secondLabel"] as! String),
                      photoKey: data["photoKey"] as! String) // Added Line

3. Then in cellForRow :

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableViewTest.dequeueReusableCell(withIdentifier: "CountryTableViewCell", for: indexPath) as! CountryTableViewCell
    let label = labels[indexPath.row]
    let storageRef = Storage.storage().reference()
    let photoRef = storageRef.child(label.photoKey)
        
    cell.labelTest.text = label.firstLabel
    cell.labelLaba.text = label.secondLabel
    cell.imageView.sd_setImage(with: photoRef) // Assuming the image view in your cell is named this
      
    return cell
}

4. Last, make sure your document structure matches the new Labels Model in the firebase console, and you have images as well in the root of your storage that match with all the photoKey s. Btw, Labels is not a very good model name, I just went with it for consistency
