Features

  • uploading/downloading multiple files concurrently or sequentially
    • grouping tasks with awesome custom operators (||| and -->)
  • supports background uploading/downloading
  • supports progress tracking (single task and group of tasks)
  • enable to resume, pause, cancel, retry the task
  • header configurable
  • request parameters configurable

Quick example

let path = NSBundle.mainBundle().pathForResource("bigfile", ofType: "zip")
let fileUrl = NSURL(fileURLWithPath: path!)!

let task = UploadTask(url: "http://server.com", file: fileUrl)
	.progress { sent, total in
		let per = Double(sent) / Double(total)
		println("uploading: \(per)")
	}
	.completed { response, json, error in
		println("completed")
	}

 
 Transporter.add(task1 ||| task2 ||| task3)                     // concurrent tasks
            .progress { bytes, total in
                let per = Double(bytes) / Double(total)
                println("concurrent tasks: \(per)")
            }
            .completed { alltasks in
                println("task1, task2, task3: completed")
            }
            .add(task4 --> task5 --> task6)                       // sequential tasks 
            .progress { bytes, total in
                println("serial tasks")
            }
            .resume()

Usage

// downloading task

let task = DownloadTask(url: downloadUrl, destination: des)
	.progress { bytes, total in
		let per = Double(bytes) / Double(total)
		println("downloading: \(per)")
	}
	.completed { response, _, error in
		println("completed")
	}


// uploading task
// upload types: File, Data, Stream

let task = UploadTask(url: "http://server.com", data: uploadData)
	.progress { sent, total in
		let per = Double(sent) / Double(total)
		println("uploading: \(per)")
	}
	.completed { response, json, error in
		println("completed")
	}


// using  `|||`  operator to create a group of concurrent tasks

Transporter.add(task1 ||| task2 ||| task3)

// using  `-->`  operator to create a group of sequential tasks

Transporter.add(task1 --> task2 --> task3)


// task

task.headers = ["key": "value"]
task.params = ["key": "value"]
task.pause()
task.cancel()
task.retry

// background handling
// add the following method in the app delegate

func application(application: UIApplication, handleEventsForBackgroundURLSession identifier: String, completionHandler: () -> Void) {
	Transporter.handleEventsForBackgroundURLSection(identifier, completionHandler: completionHandler)
}


// Transporter configurations

Transporter.headers = [key: value]
Transporter.timeoutIntervalForRequest = 30.0
Transporter.timeoutIntervalForResource = 24 * 60 * 60.0
Transporter.HTTPMaximumconnectionsPerHost = 5
