我需要将我的Alamofire调用包装在dispatch_async中吗？ [英] Do I need to wrap my Alamofire calls inside dispatch_async?

问题描述

func authenticate(completion:(success: Bool) -> Void) {
let qos = Int(QOS_CLASS_USER_INITIATED.value)
dispatch_async(dispatch_get_global_queue(qos, 0)){ () -> Void in
    Alamofire.request(.POST, CONSTANTS.Domain+"/accounts", parameters: ["" : ""]).responseJSON { (req, res, json, error)  in
         dispatch_async(dispatch_get_main_queue()){
               completion(success: true)
         }
    }
}
}

或者，我可以省略调度并保持我的代码简单吗？

Or, can I leave out the dispatch and just keep my code simple?

推荐答案

Alamofire旨在实现异步。另一方面，如果该方法具有回调，则很可能是异步的。
所以，是的，你可以省去dispatch_async调用。

Alamofire is designed to be asynchronous. On another note, if the method has as callback, most likely it is asynchronous. So, yes you can leave out the dispatch_async calls.
