You could use GCD event dispatch sources.
Apple's Concurrency Programming Guide includes a sample on how to setup a timer.

Their sample code runs the block on the main queue. If you want it on a background thread, you could pass a queue obtained with dispatch_get_global_queue instead of dispatch_get_main_queue().
