Comment on Face detection with Core Image on Live Video by sverre

Cool thanks, I can use this… Have been playing around with putting “stuff” in face just like you, recently. I am planning to use SVGKit ( https://github.com/SVGKit/SVGKit ) to add a vector mask mask (no pun intended), instead of using raster graphics that could look bad when scaled. Just an idea.

Great tutorial! It took me half an hour to fix a problem that I was having, though–I typed the ‘Main nib file base name’/'Main Interface’ field with the .xib file extension, and that didn’t work — it was creating an “internal inconsistency exception — could not load nib”. Just in case someone suffers the same silly problem.

When using XCode 4.3.3, for some reason I was unable to drag an “object” from the library into the “Objects” pane in the nib. However, double-clicking it added it automatically. Very odd. I thought I’d share in case someone else ran into this issue. Great tutorial, thanks! I’m using an older book and although the “single-view application” template is roughly equivalent to the old “view-based application”, it doesn’t work for many of the exercises in the book and I don’t yet know enough to adapt. Creating this template has solved the problem.

Thank you very much! I’m really new to this and found this very helpful! Screencasts are way more easy to understand than simple written instructions.

You should have a look a the original Apple Sample “SquareCam”. It shows how to save the image to the camera roll.

I’m trying to save the current view as an image with this code:

if ([[UIScreen mainScreen] respondsToSelector:@selector(scale)]) {
if ([[UIScreen mainScreen] scale] == 2.0) {
UIGraphicsBeginImageContextWithOptions(self.previewView.bounds.size, YES, 2.0);
} else {
UIGraphicsBeginImageContext(self.previewView.bounds.size);
}
} else {
UIGraphicsBeginImageContext(self.previewView.bounds.size);
}

[self.previewView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

UIImageWriteToSavedPhotosAlbum(viewImage, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);
I just want to save a image of the whole thing that is displaying on the screen, the “live camera” plus the overlay image.

But with this code, I’m getting a completely black image as output.

Can you help me with this? Thank you so much
