在iphone应用程序下载多个文件（目标c） [英] Downloading multiple files in iphone app(Objective c)

问题描述

在我的iPhone应用程序，我想下载多个文件，在IIS上的认证。在按钮上点击我想开始下载过程。

我知道如何使用身份验证下载文件。

  NSURLRequest * request = 
 [NSURLRequest requestWithURL：mMovieURL 
 cachePolicy：NSURLRequestUseProtocolCachePolicy 
 timeoutInterval：60.0]; 
 movieConnection = 
 [[NSURLConnection alloc] initWithRequest：request delegate：self]; 
  

并且我有两个代理方法与上述代码。

$

$ b $ p

解决方案

我之前做过，当我想同时下载10个XML文件（这是速度比排队他们一个接一个下）。我使用了这里找到的库：

http://github.com/leonho/iphone-libs/tree/master

它们很容易实现，有一些示例代码

  self.urls = [NSMutableArray arrayWithObjects：
 @http：// maps .google.com / maps / geo？output = json& q = Lai + Chi + Kok，Hong + Kong，
 @http://maps.google.com/maps/geo?output=json& q = Central，Hong + Kong，
 @http://maps.google.com/maps/geo?output=json&q=Wan+Chai,Hong+Kong，
 nil] ; 
 
 self.downloads = [[MultipleDownload alloc] initWithUrls：urls]; 
 self.downloads.delegate = self; 
  

祝你好运。

In my iPhone app I want to download multiple files which are on IIS with authentication. On a button click i want to start the downloading process.

I know how to download a file with authentication.

    NSURLRequest* request =
               [NSURLRequest requestWithURL:mMovieURL 
                             cachePolicy:NSURLRequestUseProtocolCachePolicy 
                             timeoutInterval:60.0];
    movieConnection =
            [[NSURLConnection alloc] initWithRequest:request delegate:self ];

and i have couple of delegate methods with the above code.

But how to do it with mutliple downlaods going at the same time.

Thanks,

解决方案

I've done this before when I wanted to download 10 XML files at the same time (it was much faster than queuing them to download one after the other). I used the libraries found here:

http://github.com/leonho/iphone-libs/tree/master

They were easy to implement and there's some example code on the front page to get you started.

self.urls = [NSMutableArray arrayWithObjects:
    @"http://maps.google.com/maps/geo?output=json&q=Lai+Chi+Kok,Hong+Kong",
    @"http://maps.google.com/maps/geo?output=json&q=Central,Hong+Kong",
    @"http://maps.google.com/maps/geo?output=json&q=Wan+Chai,Hong+Kong",
    nil];

self.downloads = [[MultipleDownload alloc] initWithUrls: urls];
self.downloads.delegate = self;

Good luck.
