How can you combine a custom timing curve with a spring animation to create a bounce effect that starts slowly and ends with a bounce?
AUse UIViewPropertyAnimator with a custom timing curve and spring timing parameters.
BUse UIView.animate with .curveLinear and no spring parameters.
CUse UIView.animate with .curveEaseIn only.
DUse UIView.animate with .repeat and no timing curve.
Step-by-Step Solution
Solution:
  1. Step 1: Understand spring animations

    Spring animations provide bounce effects with damping and initial velocity parameters.
  2. Step 2: Combine with custom timing

    UIViewPropertyAnimator allows combining custom timing curves with spring parameters for precise control.
  3. Final Answer:

    Use UIViewPropertyAnimator with a custom timing curve and spring timing parameters. -> Option A
  4. Quick Check:

    PropertyAnimator + spring = custom bounce timing [OK]
Quick Trick: Use UIViewPropertyAnimator for custom spring timing [OK]
Common Mistakes:
  • Using UIView.animate without spring parameters
  • Ignoring timing curves in spring animations
  • Assuming .repeat creates bounce
