Recently I am enthusiastic for developing iPhone app which can capture posters and take panorama photo!
And now its prototype can track optical flow that is distance of moving of camera view.

You can get the hierarchy of subviews on UIImagePickerController with this code.

// Recursive enumerate subviews to get hierarchy of camera view.
- (BOOL)enumSubviews:(UIView*)view withNest:(int)idx
{
	Class cl = [view class];
	char sp[255];
	memset(sp, ' ', 255);
	sp[idx*4] = 0;

	NSLog(@"%s%@\n", sp, NSStringFromClass(cl));

	for (int i = 0; i < [view.subviews count]; i++)
	{
		if ([self enumSubviews:[view.subviews objectAtIndex:i] withNest:idx+1])
			return YES;
	}

	return NO;
}

And here is a result.

PLCameraView
    PLPreviewView
        PLCameraFocusView
    UIImageView
    PLCropOverlay
        OverlayView
        PLCropOverlayBottomBar
            UIImageView
                PLCropOverlayBottomBarButton
                    UIImageView
                    UIButtonLabel
                PLCropOverlayBottomBarButton
                    UIImageView
                    UIButtonLabel
            UIImageView
                PLCameraButton
                    UIView
                        UIImageView
                PLCropOverlayBottomBarButton
                    UIImageView
                    UIButtonLabel
    UIImageView

One of UIImageView has photo taken. Keep exploring..

なぜかimap_headerinfo()の戻り値にはContent-Typeが含まれないので、
直に取得する力技で解決。

When you try to get charset of a mail on IMAP, imap_headerinfo() doesn’t include ‘Content-Type’ in the return value.
Below is a function to get type of charset from a mail header directly by calling imap_fetchheader.
