使用ASIHTTPRequest库从服务器下载视频文件(以MB大小)

Question

在我的应用程序中,我想从服务器下载视频文件并将该文件存储在IPhone文档目录中.

为了下载我正在使用ASIHTTPRequest库,我已经下载了视频(以KB大小)并存储到Document目录中.

但是,当我下载视频(以MB大小)意味着,请求需要更多的时间来进行视频下载并且没有结果(我已经等了15分钟但是没有下载).

我在我的应用程序中尝试了以下代码,这是从服务器单个下载.

- (IBAction)grabURLInBackground:(id)sender
{
     NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
     NSString *documentsDirectory = [paths objectAtIndex:0];
     NSURL *url = [NSURL URLWithString:@"http://mobile.aghaven.com/Downloads/video/Movie.m4v"];

//NSString *file = [NSString stringWithFormat:@"%@/movie.mov", documentsDirectory];

     ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
     NSString* file = [documentsDirectory stringByAppendingPathComponent:@"Movie.m4v"];

   [request setDelegate:self];
   [request setTimeOutSeconds:60];
   [request setNumberOfTimesToRetryOnTimeout:2];
   [request setDownloadDestinationPath:file];
   [request startAsynchronous];
}

- (void)requestFinished:(ASIHTTPRequest *)request

 {
    [[[[UIAlertView alloc] initWithTitle:@"Message" 
                                 message:@"Success!!!" 
                                delegate:self 
                       cancelButtonTitle:@"OK" 
                       otherButtonTitles:nil] autorelease] show];
 }

此文件(Movie.m4v)具有2.2 MB大小,当我从服务器下载此视频时,没有下载视频.

请建议我如何使用ASIHTTPRequest从服务器下载视频文件(以MB大小)？

我正在使用XCode 4.2和iOS 5 sdk.

如果任何示例代码意味着它对我很有帮助.

谢谢!!!

Answer 1

 -(void)viewDidLoad 

{

    [super viewDidLoad];

     NSURL *url = [NSURL URLWithString:@"http://mobile.aghaven.com/Downloads/video/Movie.m4v"];

     ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
     [request setDownloadDestinationPath:@"/Users/pk/Desktop/my_file.m4v"];
     [request setDelegate:self];
     [request startAsynchronous];

}

 -(void)requestFinished:(ASIHTTPRequest *)request

{

    [[[[UIAlertView alloc] initWithTitle:@"Message" 
                                 message:@"Success!!!" 
                                delegate:self 
                       cancelButtonTitle:@"OK" 
                       otherButtonTitles:nil] autorelease] show];

}

 -(void)requestFailed:(ASIHTTPRequest *)request
{

    NSLog(@"%@",request.error);

}

你会看到该文件在桌面上.
