swift：从照片库中拍摄图片并上传到firebase

到目前为止我没有找到适合自己的作品..我尝试将我的照片库（最近拍摄的照片保存在库中）中的图片上传到Firebase存储。下面swift：从照片库中拍摄图片并上传到firebase

代码是图像的保存和增加它的图书馆：

// 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) 
    } 
}

任何帮助，将不胜感激。

我曾尝试下面的代码，只给我的错误：致命错误：意外发现零而展开报名后一个可选值!:

// . . . 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]) 
     } 

    } 
}

请将您的代码添加为文本而不是图片，否则复制和修改它会困难得多。 – EmilioPelaez

对不起，我会编辑它。谢谢 – 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) 
     } 
    }) 
}
