swift：從照片庫中拍攝圖片並上傳到firebase

到目前爲止我沒有找到適合自己的作品..我嘗試將我的照片庫（最近拍攝的照片保存在庫中）中的圖片上傳到Firebase存儲。下面swift：從照片庫中拍攝圖片並上傳到firebase

代碼是圖像的保存和增加它的圖書館：

// MARK: - Save image 

@IBAction func savePhoto(_ sender: Any) { 
    UIImageWriteToSavedPhotosAlbum(licensePhoto.image!, self, #selector(image(_:didFinishSavingWithError:contextInfo:)), nil) 
} 


//MARK: - Add image to Library 

func image(_ image: UIImage, didFinishSavingWithError error: Error?, contextInfo: UnsafeRawPointer) { 
    if let error = error { 
     // we got back an error! 
     let alert = UIAlertController(title: "Error", message: error.localizedDescription, preferredStyle: .alert) 
     alert.addAction(UIAlertAction(title: "OK", style: .default)) 
     present(alert, animated: true) 
    } else { 
     let alert = UIAlertController(title: "Saved!", message: "Image saved successfully", preferredStyle: .alert) 
     alert.addAction(UIAlertAction(title: "OK", style: .default)) 
     present(alert, animated: true) 
    } 
}

任何幫助，將不勝感激。

我曾嘗試下面的代碼，只給我的錯誤：致命錯誤：意外發現零而展開報名後一個可選值!:

// . . . upload license photo to firebase 


    var data = NSData() 
    data = UIImageJPEGRepresentation(licensePhoto.image!, 0.8)! as NSData 
    // set upload path 
    let filePath = "\(FIRAuth.auth()!.currentUser!.uid)/\("userPhoto")" 
    let metaData = FIRStorageMetadata() 
    metaData.contentType = "image/jpg" 
    DataService.Instance.storageRef.child(filePath).put(data as Data, metadata: metaData){(metaData,error) in 
     if let error = error { 
      print(error.localizedDescription) 
      return 
     }else{ 
      //store downloadURL 
      let downloadURL = metaData!.downloadURL()!.absoluteString 
      //store downloadURL at database 
      DataService.Instance.dbRef.child("users").child(FIRAuth.auth()!.currentUser!.uid).updateChildValues(["userPhoto": downloadURL]) 
     } 

    } 
}

請將您的代碼添加爲文本而不是圖片，否則複製和修改它會困難得多。 – EmilioPelaez

對不起，我會編輯它。謝謝 – LizG

我找到了答案：

// . . . upload license photo to firebase 

    let storage = FIRStorage.storage().reference() 
    let tempImgRef = storage.child("tmpDir/tmpImage.jpg") 

    var data: NSData = NSData() 
    data = UIImageJPEGRepresentation(licensePhoto.image!, 0.8)! as NSData 

    let metaData = FIRStorageMetadata() 
    metaData.contentType = "image/jpeg" 

    tempImgRef.put(data as Data, metadata: metaData, completion: { (metaData, error) in 
     if error == nil { 
      print("success") 

     } else { 
      print(error?.localizedDescription as Any) 
     } 
    }) 
}
