How to cancel all requests in Alamofire's shared manager

How to cancel all requests in Alamofire's shared manager?

This is my function:

class func cancelAllRequests() {
    Alamofire.Manager.sharedInstance.session.getTasksWithCompletionHandler { (dataTasks, uploadTasks, downloadTasks) in
        self.each(dataTasks, function: self.cancel)
        self.each(uploadTasks, function: self.cancel)
        self.each(downloadTasks, function: self.cancel)
    }
}

class func cancel(index: Int, element: AnyObject) {
    if let task = element as? NSURLSessionTask {
        task.cancel()
    }
}

class func each<T>(array: [T], function: (Int, T) -> ()) {
    for (index, t) in enumerate(array) {
        function(index, array[index])
    }
}

Can it works?

Solution

  • Use NSURLSession's invalidateAndCancel method:

    manager.session.invalidateAndCancel
