我试图用ASIHTPP下载文件。我试过我的越狱Ipad，看到代码下载文件，但没有在Documet文件夹。那怎么了？
在Xcode不是一个错误只有一个警告说，documtensdirectory一个未使用的变量是。

{

   NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
   NSString *documentsDirectory = [paths objectAtIndex:0];
   NSURL *url = [NSURL URLWithString:@" http://db.tt/5WP2pia"];
   ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
   [request setDownloadDestinationPath:@"/var/root/osk.rar"] 
   [request setDelegate:self];
   [request startAsynchronous];

}

推荐答案

将文档文件夹设置为目标路径。您需要在文档文件夹中指定一个文件名作为下载路径，使其正常工作：

You are setting the documents folder as destination path. You need to specify a file name inside the documents folder as download path like this to make it work:

[request setDownloadDestinationPath:[documentsDirectory stringByAppendingPathComponent:@"myfile.extension"]];

将下载的数据保存在文件 myfile.extension 在文件夹中。

This saves the downloaded data in the file myfile.extension inside the documents folder.

您还应设置一个临时下载路径，否则下载的字节存储在内存中，直到下载完成，而不是在文件。

You should also set a temporary download path, otherwise the downloaded bytes get stored in the memory until the download is finished rather than in a file.
