alamofire

问题 I'm using Alamofire to make a call to a webservice which takes a pretty long time to load. If the app goes into the background I get stuck with my loader when I return to the app. I imagine it's because the call never returns anything to my completion handler. How can I address this problem? 回答1: You can use background fetching to solve this problem. It can be done in the following way in Swift 3: var backgroundTask: UIBackgroundTaskIdentifier? // global variable backgroundTask =

问题 i have a json data which gives the following information: let data = [ { "QuestionTitle" : "Entomology is the science that studies", "Id" : 205, "Options" : [ { "Option" : "Insects", "Id" : 810 }, { "Option" : "The origin and history of technical and scientific terms", "Id" : 811 }, { "Option" : "The formation of rocks", "Id" : 812 }, { "Option" : "Behavior of human beings", "Id" : 809 } ] }, { "QuestionTitle" : "A train running at the speed of 60 km\/hr crosses a pole in 9 seconds.

问题 I have the following functions. I'm trying to pass allItems array into the completion block of requestItems , but I get a crash as it says it's nil. I removed the completion to check that item has a value and it does. That means that the completion executes before the for loop. Is there another approach for this? Something like Promises in Javascript that will execute the completion when the for loop has finished. func requestItems(_ data: [String: Any], completion: (Bool, [Item]) -> Void) {

问题 I'm novice programmer and I've been working on movie app and couldn't figure out why Alamofire returns my single parameters from JSON response but doesn't do it in for loop. Here is the code. This function is inside class. class oneMovie: ObservableObject{ @Published var Movie = Movies() private let API : String var url : String init(ID: String){ self.API = "API" self.url = "url.to.somewhere\(ID)" MovieGetter(URL: url) } func MovieGetter(URL: String){ AF.request(URL).responseJSON { (response)

问题 I am using URLSession's dataTask method with a completion handler. The error in response is nil, but the data object returns something, it returns 0 bytes of data. I was using Alamofire library firstly, I thought there is something wrong with it because I started using newer version so I stated using my own implementation of Alamofire just so I don't have to rewrite all the calls I already have in my app. It still returns 0 bytes of data. When I use the same URL in the Playground with a
