trimDuration

Declaration

var trimDuration: TimeInterval? { get set }

Discussion

The framework calculates AnimationAction/duration, but you can set this property to override it. This property is nil by default, which indicates that the animation stops after one play that spans AnimationAction/duration.

If you set a non-zero value for this property and both AnimationAction/trimStart and AnimationAction/trimEnd are nil, the animation observes this property as an edited duration.

When you set AnimationAction/repeatMode to make the animation repeat:

• If this property is nil, the animation repeats forever.

• If set to a value greater than AnimationAction/duration, the animation repeats for the specified duration.
