快速示例
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) // serial tasks
.progress { bytes, total in
println("serial tasks")
} .resume()
用法
// downloading tasklet 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, Streamlet 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")
}// tasktask.headers = ["key": "value"]
task.params = ["key": "value"]
task.pause()
task.cancel()
task.retry// background handling// add the following method in the app delegatefunc application(application: UIApplication, handleEventsForBackgroundURLSession identifier: String, completionHandler: () -> Void) {
Transporter.handleEventsForBackgroundURLSection(identifier, completionHandler: completionHandler)
}// Transporter configurationsTransporter.headers = [key: value]
