使用Firebase Storage Swift中的图像引用数据库中的Firebase用户

Question

通常情况下,我可以在网上找到这个问题的答案,但由于它如此新,我一直遇到麻烦.

当我让用户登录应用并为他们的个人资料选择4-5张图片时,如何将这些图片存储在Firebase存储中并将这些图像引用到Firebase数据库中的该用户？

谢谢

您首先将它们上传到Firebase存储,然后将该网址存储在Firebase数据库中

let storage = FIRStorage.storage()
let data: NSData = myImageData
let userProfilePic = storageRef.child("users/abc/profileimage.jpg")

let uploadTask = userProfilePic.putData(data, metadata: nil) { metadata, error in
  if (error != nil) {
    // Uh-oh, an error occurred!
  } else {
    let downloadURL = metadata!.downloadURL
    // store downloadURL in db
    storeUserProfileInDB(downloadURL)
  }
}

func storeUserProfileInDB(profileImgUrl: NSURL) {
    let ref = FIRDatabase.database().reference()
    let key = ref.child("users").childByAutoId().key

    let dictionaryUser = [ "userName"    : name! ,
                           "imageUrl" : profileImgUrl.absoluteString,
                           ]

    let childUpdates = ["/users/\(key)": dictionaryTodo]
    ref.updateChildValues(childUpdates, withCompletionBlock: { (error, ref) -> Void in
        //save
    })

}
