如何在 SwiftUI 或 Swift 5 中从 Firebase 存储下载或检索图像

Question

我必须在 else 正文中编写什么才能从 firebase 存储中检索图像并将其显示在 UI 中？

public func downloadFile(url: String){

    var img: Image?

    let storage = Storage.storage()
    let storageRef = storage.reference()
    let imageRef = storageRef.child("Wallpapers/Cars/Wallpaper1.jpg")
    imageRef.downloadURL { (url, err) in
        if let err = err{
            print("Error! Unable to download")
        }
        else{

        }
    }

}

对于 swift 5，你可以使用这个：

let Ref = Storage.storage().reference(forURL: yourUrl)
Ref.getData(maxSize: 1 * 1024 * 1024) { data, error in
    if error != nil {
        print("Error: Image could not download!")
    } else {
        yourImageView.image = UIImage(data: data!)
    }
}

希望能帮助到你...
