NSOutputStream: delete existing file if stream is incomplete?

Question

I'm using NSUrlConnection and NSOutputStream to write the file. But when the file doesn't exist or there is an error while downloading I want to be able to remove the incomplete downloaded file.

Is there a operation for this? Because otherwise I get a file with 0 bytes content...

Handling Stream Errors like this:

- (void)stream:(NSStream *)stream handleEvent:(NSStreamEvent)eventCode {

NSLog(@"stream:handleEvent: is invoked...");
switch(eventCode) {

    case NSStreamEventErrorOccurred:

    {
       //give alert about error
       // remove current incomplete download data here
       break;
    }

    // continued ....

   }

 }

Which delegate do I need for this method? – user1066006 Aug 21 '12 at 11:35
add NSStreamDelegate in your interface. Plus set yourNSOutputStreamobject delegate= self – Paresh Navadiya Aug 21 '12 at 11:37
