Remarks
Layer-based animations are disabled by UIViews except within UIView animation blocks. Layer-based animations within such blocks ignore the blocks' duration and operate at their own specified duration, either the implicit default of 0.25 seconds or an explicit length. This is shown in the following example, in which the UIView animation block's duration is 1.0, but in actuality, the layer-based implicit opacity animation ends in 0.25 seconds and the re-positioning runs for 10 seconds.
UIView.AnimateAsync(1.0, () => {
imgView.Layer.Opacity = 0.0f;
var theAnim = CABasicAnimation.FromKeyPath("position");
theAnim.From = NSObject.FromObject(firstPosition);
theAnim.To = NSObject.FromObject(secondPosition);
theAnim.Duration = 10.0;
imgView.Layer.AddAnimation(theAnim, "AnimateFrame");
});
Constructors
| Name | Description |
|---|---|
| CAAnimation() |
Creates a new CAAnimation with default values. |
| CAAnimation(NativeHandle) |
A constructor used when creating managed representations of unmanaged objects. Called by the runtime. |
| CAAnimation(NSCoder) |
A constructor that initializes the object from the data stored in the unarchiver object. |
| CAAnimation(NSObjectFlag) |
Constructor to call on derived classes to skip initialization and merely allocate the object. |
