I have this firebase Database Structure:
我有这个firebase数据库结构：
Main
----- Name 1
--------value 1
--------value 2
--------value 3
----- Name 2
--------value 1
--------value 1
--------value 1
I'm trying to get all the key values and storing into an array of a custom class.
我正在尝试获取所有键值并存储到自定义类的数组中。
My custom class has an init:
我的自定义类有一个init：
init(name: String, photo: String) {
self._name = name
self._photo = photo
}
So in my View controller I have:
所以在我的View控制器中我有：
var array = [customClass]()
let ref = Database.database().reference().child("Main")
func getInfo(){
Ref.observeSingleEvent(of: .value) { (snapshot) in
var arrayTemp = [customClass]()
for child in snapshot.children {
let snap = child as! DataSnapshot
let name = snap.key
let custom = customClass(Name: name, photo: "")
arrayTemp.append(custom)
}
self.array = arrayTemp
self.collectionView.reloadData()
}
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
if let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as? Cell {
let custom: Custom!
custom = array[indexPath.row]
cell.configureCell(custom)
return cell
} else {
return UICollectionViewCell()
}
}
and here is the cell:
这是细胞：
class Cell: UICollectionViewCell {
@IBOutlet weak var Thumb: UIImageView!
@IBOutlet weak var NameLbl: UILabel!
var custom: CustomClass!
func configureCell(_ custom: customClass) {
self.custom = custom
NameLbl.text = self.custom.customName.capitalized
var url = URL(string: self.custom.photoUrl)
if url == nil {
url = URL(string: "")
}
Thumb.sd_setImage(with: url)
}
}
}
My issue is that if i print name I have all the values from the Db but when I reload the collection View I see the number of item correct but the name is just the first element repeated x time... Any help?
我的问题是，如果我打印名称我有Db的所有值，但当我重新加载集合视图我看到项目的数量正确，但名称只是重复x时间的第一个元素...任何帮助？
