    <p>UIImageView is just fine for animating about the display (UIViews are lightweight wrappers around CALayers, which are just textures stored on the graphics card), but you do need to use the begin / commit animation block to get smooth animation. Using that, you can retrieve the current position of the view by accessing the backing layer of the UIView and obtaining its presentation layer. Dustin Bachrach has a <a href="http://dbachrach.com/blog/2008/04/07/instantaneous-frame-of-moving-core-animation-views/" rel="nofollow noreferrer">post</a> that describes just how to do this. Basically, the presentation layer is Core Animation's closest approximation to where the actual layer is at any given time, so its frame is the frame of your UIView at that instant.</p> <p>I'm not sure that touch events will find their way to the view as it's moving across the screen, so if you need to have the UIImageView respond to touches you may need to replace it with a CALayer, insert it as a sublayer of your main UIView's layer, and call the hitTest method on the presentationLayer of that main layer. That should return the presentationLayer of your moving layer if it was clicked on, or the background layer if not.</p> <p>Honestly, I wouldn't go with OpenGL unless you absolutely had to for performance reasons, because it is a lot harder to code for than what Core Animation provides you with UIViews and CALayers. I've been able to animate 50 moving translucent layers at 60 FPS (100 at 30 FPS) using just UIViews and CALayers.</p>

    1. COThanks for the hint. I eventualy managed to get the UIView frame at "animation time".

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
