从后台提取调用时，Alamofire无法正常工作

Question

I'm using background fetch in an iOS app to schedule some notifications and I need to fetch some data from server But when i create an Alamofire request the surver returns the data but alamofire does not calles my compilation handler (responseString)

the exact same code works perfectly while my app is on forground.

Alamofire.request(url, method: method ?? HTTPMethod.get, parameters: parameters,
        encoding: encoding ?? URLEncoding.default, headers: headers)
        .responseString{
        (afResponse : DataResponse<String>) -> Void in
    ....
}

I used AlamofireNetworkActivityLogger to check weather the response is created and fetched and the result was true. but my compilation handler not getting called!

any thing else should I consider while using Alamofire in background?

Answer 1

Have you tested if it is working as suggested in Alamofire network calls not being run in background thread

We may have to start the call from background thread instead of the main thread (as it is the default behaviour).
