#FWTOverlayView

FWTOverlayView extends scrollview and make it easy to add a floating overlay view. The overlay view hovers through your scrollview frame and helps tracking the current offset. This component is inspired by Path app and tries to expose a generic and flexible interface. It uses associative reference to add a custom property to a UIScrollView category.

##Requirements

• XCode 4.4.1 or higher
• iOS 5.0

##Features FWTOverlayView is a small collection of objective-c categories.

• UIScrollView (FWTRelativeContentOffset), adds the relative content offset property
• UIScrollView (FWTOverlayView) hides a private helper class and exposes a small set of properties to make the overlay view customization easy
• UITableView (FWTOverlayView) adds a handy property to get the indexPath from the current overlay view position.

##How to use it: configure

####UIScrollView (FWTRelativeContentOffset)

• fwt_relativeContentOffset the point, in the unit coordinate space, at which the origin of the content view is offset from the origin of the scroll view
• fwt_relativeContentOffsetNormalized:(BOOL)normalized returns the relative content offset and if enabled it clamps to [0, 1] values

####UIScrollView (FWTOverlayView)

• fwt_overlayView the custom view to display on top of the scrollview
• fwt_overlayViewEdgeInsets the inset or outset margins for the edges of the available overlay view area
• fwt_overlayViewFlexibleMargin
• fwt_overlayViewHideAfterDelay
• fwt_layoutBlock
• fwt_dismissBlock

####UITableView (FWTOverlayView)

• fwt_overlayViewIndexPath returns the index path identifying the row and section below the overlay view

##Demo The sample project shows how to use the categories and how to create a custom overlay view.

	- (void)loadView
	{
		[super loadView];

		// set and configure the overlay view	
		CGRect frame = CGRectMake(.0f, .0f, 80.0f, 34.0f);
    	self.tableView.fwt_overlayView = [[[OverlayView alloc] initWithFrame:frame] autorelease];
    	self.tableView.fwt_overlayViewEdgeInsets = (UIEdgeInsets){2.0f, 2.0f, 2.0f, 10.0f};
    	self.tableView.fwt_overlayViewFlexibleMargin = UIViewAutoresizingFlexibleLeftMargin;
    }
    
    - (void)scrollViewDidScroll:(UIScrollView *)scrollView
	{
		// update the overlay view displayed values
    	Item *item = [self.data objectAtIndex:self.tableView.fwt_overlayViewIndexPath.row];
    	OverlayView *overlayView = (OverlayView *)scrollView.fwt_overlayView;
    	overlayView.textLabel.text = item.timeString;
    	overlayView.detailTextLabel.text = item.dateString;
	}
