iPhone: Once I have redirected NSLog to a file, how do I revert it to the console?

Solution
This doesn't explicitly answer your question, but if all you need to redirect is NSLog's output, then I would consider using a wrapper around NSLog() and deciding there whether to send to file or to regular NSLog/stderr based on a flag that you keep around that the user can control.
(It feels like a surprising design to me to fundamentally redirect the stderr stream to accomplish this-- and with a wrapper above the NSLog level, you could just as easily choose to send the output to both places if you ever wanted.)
Problem
I'm using: ``` #if TARGET_IPHONE_SIMULATOR == 0 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *logPath = [documentsDirectory stringByAppendingPathComponent:@"console.log"]; freopen([logPath cStringUsingEncoding:NSASCIIStringEncoding],"a+",stderr); #endif ``` .. to redirect NSLog to a file, which works great incidentally. I want to make logging to file something the user of my app can turn on and off.. so does anyone know how I go about redirecting NSLog/stderr back to the console? Thanks!
