NSFileManager removeItemAtPath blocks the main thread

Question

I am working on an application that can delete a large number of files. When I call the removeItemAtPath NSFileManager method, the user interface of the application is blocked until the operation is completed (this may take some time).

I tried to fix this by calling using performSelectorInBackground method, but it did not work.

Any ideas?

Thanks in advance.

You can try using GCD to do this in the background thread.

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void) {
  [[NSFileManager defaultManager] removeItemAtPath:path];
});
