Need help Cydia App Root Rights

问题:

i tried to download a File with ASIHTPP. I tried on my jailbroken Ipad and see that the Code download a File but no in the Documet Folder. So what is wrong? In Xcode is not a Error only a Warning that the documtensdirectory a unused variable is.

 - (IBAction)grabURLInBackground:(id)sender
{

   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];

}

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"]];

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

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.
