Hacking UIView animation blocks for fun and profit

In this article, I'm going to explore a way that we can create views that implement custom Core Animation property animations in a natural way.

As we know, layers in iOS come in two flavours: Backing layers and hosted layers. The only difference between them is that the view acts as the layer delegate for its backing layer, but not for any hosted sublayers.

In order to implement the UIView transactional animation blocks, UIView disables all animations by default and then re-enables them individually as required. It does this using the actionForLayer:forKey: method.

Somewhat strangely, UIView doesn't enable animations for every property that CALayer does by default. A notable example is the layer.contents property, which is animatable by default for a hosted layer, but cannot be animated using a UIView animation block.

public class BaseActivity extends AppCompatActivity 
{
	public DrawerLayout drawerLayout;
    public ListView drawerList;
    private ActionBarDrawerToggle drawerToggle;
	
    protected void onCreate(Bundle savedInstanceState)
    {
    	// R.id.drawer_layout should be in every activity with exactly the same id.
    	drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

Rails naming conventions

General Ruby conventions

Class names are CamelCase.

Methods and variables are snake_case.

Methods with a ? suffix will return a boolean.

var i = 0;
function unroll_me_unsubscribe() {
	// Bail if share modal (indicating free limit reached) is encountered.
	if ( jQuery( '#fb-root' ).length > 0 ) { return; }
	var unsub_link = jQuery( '.LetterList a.uicon-set-unsubscribe:first' );
	if ( unsub_link.length > 0 ) {
		document.getElementById( unsub_link.attr( 'id' ) ).click();
		if ( i++ < 6000 ) { /* Upper limit in case something goes wrong. */
			setTimeout( unroll_me_unsubscribe, 1500 );
		}
