标题：如何在应用终止时处理NSURLSession

swift
func applicationWillTerminate(_ application: UIApplication) {
    let sessionConfig = URLSessionConfiguration.default
    let session = URLSession(configuration: sessionConfig)
    
    let task = session.dataTask(with: URL(string: "https://www.example.com")!) { (data, response, error) in
        // 处理网络请求结果
    }
    
    // 设置task的completionHandler
    task.taskDescription = "com.example.app.backgroundTask"
    task.resume()
}
func applicationDidEnterBackground(_ application: UIApplication) {
    if let task = session.dataTask(with: URL(string: "https://www.example.com")!) {
        task.taskDescription = "com.example.app.backgroundTask"
        task.resume()
