Automatically set the height of a UIScrollView to fit it's content.

UIScrollView-auto-height.mm

CGFloat scrollViewHeight = 0.0f;
CGFloat scrollViewWidth = 0.0f;

for (UIView *view in scrollView.subviews) {
	CGFloat height = (view.frame.size.height + view.frame.origin.y);
	scrollViewHeight = ((height > scrollViewHeight) ? height : scrollViewHeight);
	
	CGFloat width = (view.frame.size.width + view.frame.origin.x);
	scrollViewWidth = ((width > scrollViewWidth) ? width : scrollViewWidth);
}

[scrollView setContentSize:(CGSizeMake(scrollViewWidth, scrollViewHeight))];
