The recommended way to have them performed on the main thread is to use a block and GCD dispatch_async (dispatch_get_main_queue (), …). The recommended way to use performSelector these days is, in effect, not to use it. There are situations where it doesn’t satisfy the ARC memory management safety guarantees. In almost all cases, the GCD+block solution is simpler and better. If you must use performSelector, then you can write your own glue method that takes an object parameter and invokes the API that takes the scalar parameter. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
