I am not sure that I understand your question but have you read the "Replacing Run-Loop Code" section in the Concurrency Programming Guide? For instance, it suggests using dispatch_sources, and so on, rather than NSTimer methods. In my own code, I think that I have migrated completely to the use of GCD. -- Rick *------------------------------------------------- * Frederick Bartram * PGP key id: 0x63fa758 keyserver: http://keyserver.pgp.com */
