Take a look at the UIApplicationDelegate protocol. I haven't played with it, but: - - applicationProtectedDataWillBecomeUnavailable: looks like a promising direct notification that the phone is going to be locked (provided the device is using content protection and a passcode). It's a bit of a misappropriation of the notification, but other options (such as -applicationWillResignActive:) are going to have side effects because they can be triggered by other events. - -- Conrad Shultz Synthetiq Solutions www.synthetiqsolutions.com -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.14 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk5yWHwACgkQaOlrz5+0JdVXiwCfXCh1RiGWkbz6pOJBVAkqgM/n UfgAn1Enl23LuGAI8a2XgaI3s1zitF6W =X2vs -----END PGP SIGNATURE----- _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
