Record iOS screen contents to .mp4 video file

ASScreenRecorder

ASScreenRecorder is a screen recorder for iOS. It allows you to easily create demo videos of your iOS apps. It doesn't use any private APIs and is pretty easy to use. By default the video will be saved to the camera roll, though you can save to a specified file URL if you prefer.

Some sample videos can be found here. Make sure you select HD playback to see the full quality video.

Which files are needed?

• ASScreenRecorder.h
• ASScreenRecorder.m

How to use it

To instantiate the screen recorder, use [ASScreenRecorder sharedInstance], a sharedInstance singleton is convenient because you can begin recording in one view controller, navigate through your app and stop recording in a different view controller without having to pass ASScreenRecorder instances from one controller to another.

If you want to record a demo video of your app, I'd recommend adding a UIGestureRecognizer to your view. You can then start and stop recording without needing to add extra buttons to your User Interface.

Add a UIGestureRecognizer (in viewDidLoad etc):

UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(recorderGesture:)];
tapGesture.numberOfTapsRequired = 2;
tapGesture.delaysTouchesBegan = YES;
[self.view addGestureRecognizer:tapGesture];

Respond to UIGestureRecognizer:

- (void)recorderGesture:(UIGestureRecognizer *)recognizer
{
    ASScreenRecorder *recorder = [ASScreenRecorder sharedInstance];
    
    if (recorder.isRecording) {
        [recorder stopRecordingWithCompletion:^{
            NSLog(@"Finished recording");
        }];
    } else {
        [recorder startRecording];
        NSLog(@"Start recording");
    }
}

The included example project demonstrates the use of a UIViewController category to simplify adding ASScreenRecorder to your view controllers.
