mf - The cameraOverlayView blocks camera buttons
"I am overlaying an image over my UIImagePickerController and I want to
use the default buttons to control flash, cameraDevice (I am testing on an
iPhone 4.0).
The buttons remain visible but they can't be pushed." |

Monte Ohrt - Camera Image Orientation
"When you save the photo, it is possible that this information could get lost,
depending on the way you save it... I ran into a problem when trying to save
the camera image with UIImagePNGRepresentation(). For some reason this
loses the orientation info. I switched to UIImageJPEGRepresentation() and all
is well now." |

MF - Taking more then one picture
"I'm trying to allow the users of my application to take more then one picture
without having to press the "take picture" button on my application again."
...
"Take a look at the AVFoundation framework additions in 4.0 (and even bet-
ter 4.1 if you have access to that). You can take pictures entirely under your
control and without using the standard picker controller." |

so - iPhone AVFoundation camera orientation
| Code: | - (void)deviceOrientationDidChange{
UIDeviceOrientation deviceOrientation = [[UIDevice currentDevice] orientation];
AVCaptureVideoOrientation newOrientation;
if (deviceOrientation == UIDeviceOrientationPortrait){
NSLog(@"deviceOrientationDidChange - Portrait");
newOrientation = AVCaptureVideoOrientationPortrait;
}
else if (deviceOrientation == UIDeviceOrientationPortraitUpsideDown){
NSLog(@"deviceOrientationDidChange - UpsideDown");
newOrientation = AVCaptureVideoOrientationPortraitUpsideDown;
}
// AVCapture and UIDevice have opposite meanings for landscape left and right (AVCapture orientation is the same as UIInterfaceOrientation)
else if (deviceOrientation == UIDeviceOrientationLandscapeLeft){
NSLog(@"deviceOrientationDidChange - LandscapeLeft");
newOrientation = AVCaptureVideoOrientationLandscapeRight;
}
else if (deviceOrientation == UIDeviceOrientationLandscapeRight){
NSLog(@"deviceOrientationDidChange - LandscapeRight");
newOrientation = AVCaptureVideoOrientationLandscapeLeft;
}
else if (deviceOrientation == UIDeviceOrientationUnknown){
NSLog(@"deviceOrientationDidChange - Unknown ");
newOrientation = AVCaptureVideoOrientationPortrait;
}
else{
NSLog(@"deviceOrientationDidChange - Face Up or Down");
newOrientation = AVCaptureVideoOrientationPortrait;
}
[self setOrientation:newOrientation];
}
