Currently, I realize that you can't not caught home and lock button simultaneously in iOS app? If my conclusion is wrong, please point at to me how to detect this event.

Thanks,

@0x7fffffff Snap Chat does it by detecting the touches cancelled event...it will only work if the user does it while touching the screen — borrrden, Jan 08 '13 at 02:29
@borrrden Hmm, interesting. Wouldn't that open the door for a lot of false positives? — Mick MacCallum, Jan 08 '13 at 02:31

@borrrden your blog.chpwn.com/post/38491252231 link has no content. Do you have any alternative solution? Thanks a lot. — Tulon, Apr 03 '17 at 06:55

Your app delegate method - (void)applicationWillResignActive:(UIApplication *)application will be called when the user takes a screenshot. If you want to emulate SnapChat then just hide your window in this method (be sure to unhide it in - (void)applicationDidBecomeActive:(UIApplication *)application)

"Your app delegate method - (void)applicationWillResignActive:(UIApplication *)application will be called when the user takes a screenshot" -> I checked and delegate method wasn't called when user takes a screenshot. I have a solution based on borrrden guide. – Soa Nguyen Jan 09 '13 at 04:16
