<p>ASDisplayNode provides thread-safe access to most of UIView and CALayer properties and methods, traditionally unsafe.</p>
|
|
|
|
<p>Using them will not cause the actual view/layer to be created, and will be applied when it is created (when the view
|
|
or layer property is accessed).</p>
|
|
|
|
<p>After the view is created, the properties pass through to the view directly as if called on the main thread.</p>
|
|
|
|
<p>See UIView and CALayer for documentation on these common properties.</p>

|
<p>If this node was measured, calling this method triggers an internal relayout: the calculated layout is invalidated,
|
|
and the supernode is notified or (if this node is the root one) a full measurement pass is executed using the old constrained size.</p>
|
|
|
|
<p>Note: If the relayout causes a change in size of the root node that is attached to a container view
|
|
(table or collection view, for example), the container view must be notified to relayout.
|
|
For ASTableView and ASCollectionView, an empty batch editing transaction must be triggered to animate to new row / item sizes.</p>

<p>This is like UIView’s contentMode property, but better. We do our own mapping to layer.contentsGravity in
|
|
_ASDisplayView. You can set needsDisplayOnBoundsChange independently.
|
|
Thus, UIViewContentModeRedraw is not allowed; use needsDisplayOnBoundsChange = YES instead, and pick an appropriate
|
|
contentMode for your content while it’s being re-rendered.</p>
