我被困了几个小时，但我无法弄清楚。我对编程还是新手也许你可以帮助我
我已经创建了一个函数，可以上传 firebase Storage 中的所有内容
//this is to call the other class
var discover = MainViewController()
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
let image = info[UIImagePickerController.InfoKey.originalImage] as! UIImage
imageCam.image = image
MainViewController.stuffImages.append(image)
MainViewController.Stuff.append("yes")
picker.dismiss(animated: true, completion: nil)
}
/// this is how it looks in the collection view
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return MainViewController.Stuff.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as! DiscoverCollectionViewCell
cell.titleLable.text = MainViewController.Stuff[indexPath.item]
cell.imageView.image = MainViewController.stuffImages[indexPath.item]
return cell
}
如何在 firebase 中调用我的存储并将其放置在 cell.imageView.image
最佳答案
我通常会创建一个单独的数据源文件，如下所示。
class DiscoverCollectionDataSource: NSObject, UICollectionViewDataSource {
private var stuffs: [String]
private var stuffImages: [UIImage]
init(stuffs: [String], stuffImages: [UIImage]) {
self.stuffImages = stuffImages
super.init()
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return self.stuffImages.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as! DiscoverCollectionViewCell
cell.gamerShopControllerDelegate = self.gamerShopControllerDelegate
let stuffTitle = self.stuffs[indexPath.row]
let stuffImage = self.stuffImages[indexPath.row]
cell.titleLable.text = stuffTitle
cell.imageView.image = stuffImage
return cell
}
}
之后，您可以在 Collection View 中链接数据源。
class DiscoverCollectionView: UICollectionViewController {
// Properties
var stuffs: [String]
var stuffImages: [UIImage]
lazy var dataSource: DiscoverCollectionDataSource = {
return DiscoverCollectionDataSource(stuffs: self.stuffs, stuffImages: self.stuffImages)
}()
override func viewDidLoad() {
super.viewDidLoad()
// Collection View
collectionView?.dataSource = dataSource
}
}
最后，您可以从 DiscoverCollectionView 中的 API 获取数据，也可以将数据传递到 DiscoverCollectionView 中。
希望有帮助。
