FireBase照片上傳修正流程

let bookItemRef = self.ref!.child(values.booktitle.lowercased())
let storageImageRef = Storage.storage().reference().child("BookRentImage").child("\(values.booktitle).jpg")

let uploadTask = storageImageRef.putData(self.ImageData!,metadata:nil){(data,error) in
	if error != nil{
		print(error.localizedDescription)
		return
		}
	// KVO應用
	uploadTask.observe(.success, handler:{(snapshot) in 
		// 下載剛剛上傳圖片的URL
		storageImageRef.downloadRef{(url,error) in 
			// 要先讓error 被指派為error，才能使用error
			if let error = error{
					print("失敗",error.localizedDescription)
			}else{
				// absoluteString完整的網域名稱
			if let imageFileURL = url?.absoluteString{
					// 確認是否為正確的網址
					print("photoImageUploadSuccess:",imageFileURL)
			}
	// 新增bookImage的url上去，因為如果按下上傳 要傳url要等到上傳結束
	bookItemRef.child(values.booktitle).setValue(bookItem.ImagetoDictionary(),withCompletionBlock:{ (error,ref) in 
		if error = nil{
			let alertController = UIAlertControler(title:"Upload Image Success!",message:"Congradulation",preferredStyle: .alert)
			let alertAction = UIAlertAction(title:"OK", style:.cancel, handler:nil)
			alertController.addAction(alertAction)
			self.present(alertControler,animated:true, completion: nil)
			}
	})
	
	
	bookItem = Book(booktitle: values.booktitle, bookauthors: values.bookauthors, bookISBN: values.bookISBN, bookimage: self.uploadURL)
	// 新增Book的等等資訓
	bookItemRef.setValue(bookItem.toDictionary(),withCompletionBlock:{ (error,ref) in
	if error == nil {
	let alertController = UIAlertController(title: "Upload Success", message: "Congradulation", preferredStyle: .alert)
	let alertAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
            
	alertController.addAction(alertAction)
	self.present(alertController, animated: true, completion: nil)
