JGFWinkCamera is an iOS camera framework that will take a photo when you wink.
This is a fun example of the power of AVFoundation.
To use in your own app you need to create an instance of JGFWinkController, then you need to make that instance a child of one of your own view controllers. JGFWinkCamera doesn't come with any UI for capturing photos, you need to build that yourself. However, I believe that that is part of the flexibility of this project. You can create whatever UI you want.
JGFWinkCamera *camera = [JGFWinkCamera cameraWithDelegate:self];
if ( camera != nil )
{
[self addChildViewController:camera];
camera.view.translatesAutoresizingMaskIntoConstraints = NO;
[self.view addSubview:camera.view];
NSDictionary *views = @{ @"camera" : camera.view };
[self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|[camera]|" options:0 metrics:nil views:views]];
[self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|[camera]|" options:0 metrics:nil views:views]];
[self.view addSubview:camera.view];
[camera didMoveToParentViewController:self];
}JGFWinkCamera will let you know when key events have occurred:
#pragma mark - JGFCameraDelegate
// Callback designed for you to provide feedback of an impending photo capture to your users.
- (void)camera:(JGFWinkCamera *)camera willShutterIn:(NSTimeInterval)time
{
if ( time > 0 )
{
[self _animateRemainingTime:time animationDuration:camera.feedbackIntervalWhileWaitingForShutter];
}
else
{
[self _animateShutter];
}
}
// Called when a photo is captured. This is your chance to save the photo.
- (void)camera:(JGFWinkCamera *)camera didCapturePhoto:(UIImage *)photo
{
[self.lastCapture setImage:photo];
}
