Need to add 'live face' detection into my iOS app, so that user cannot use a photo to cheat the app.
I think the detect blink in CIImage won't work it's possible user won't blink for about 5 seconds and the app need to be much more responsive than that.
Thanks in advance!

I have a website to play the game. When user plays the game in my web, the ios device auto sleep and turn off the screen then the game can't play anymore.
Do you know that and any idea for that?
Thanks so much!
I understand that you want to prevent the user's device to go to sleep when your game is open but the user doesn't touch the screen for a period of time.
There is no official support in iOS for this kind of feature.
NoSleep.js tries to offer some "hacky" way to keep the device awake, but according to it's issues it's not very reliable and clearly not future-proof.
If you want to have more control on the device consider the creation of a native app for your game.
I currently have an app that displays the front facing camera atop a video preview layer. By default in iOS 9, the preview layer is interrupted/paused and will not resume until split-view is dismissed. Based on the nature of the app, maintaining the running camera preview layer while multitasking is essential.
Is there any way to force the capture session to continue previewing while in split view?
Update: Seems as if Apple does not allow any sort of camera use while the device has more than one application open. You can, however, invoke UIImagePickerController in order to take a photo while in split-view. Of course this solution only allows you to snap a single photo, and nothing more. Hope this helps someone!
I'm been learning Swift and iOS development and am interested in making an application that uses the camera on the back of the iPhone to shoot slow motion video and then allow the user to use a slider to move through the video normally, but also to move frame by frame. Of course, this would be regulated by a button that transitioned the user from "normal navigation" to frame by frame. Can anyone point me in the right direction? Are there any resources where I can read about using the "slo-mo" feature in a custom app? Thanks.
If you don't want the user to be able to save the slow-mo video, what you could do is take a video shot, then have the app play it back in slow-mo. You can do all this using the AVFoundation framework. Here are some links to help you out:
Taking Control of the iPhone Camera in iOS 8
Objective-C: How to do slow-motion video in iOS (yes, this is for Objective-C, but you can change the code to Swift or just copy and paste it into a new Objective-C file)
I'm trying to create an Xcode Objective-C function that can be called from a button tap, that will record the contents of a UIView and its subviews (or a fixed section of the screen e.g. 320x320 in the center) and then allow the user to save the video to their iPhone camera roll. I also want to include the audio that is being played by the app at the time of the recording e.g background music and sound effects.
I'm having trouble finding any info on this as their seems to be a lot of people trying to record their running app for external purposes like the app store video preview. I need my video captured within the app, to be used as an app feature.
Does anyone know if this can be done or know a website or tutorial where I can learn what's needed? Thanks
I know this post is two years old, but for anybody who comes along who might need to record their iOS app's screens and save them to the phone's camera roll or even a specific URL, take a look at https://github.com/alskipp/ASScreenRecorder
I've tried it and it works! The frames per second aren't 60 so I don't know how well it would work if you were trying to record an action game, but it's still pretty awesome.
You can't do that with just one function, check that project:

I am creating an iPad app that is to be used in a public kiosk, and am playing with different ways of knowing when a user is present, has gone away or a new user has come along. I wondered therefore if this would be possible using a iOS 5 Core Image detection script, but I need to be able to use the camera feed without it actually showing the user. Is this in any way possible?
