iOS Swift - Animations
What does the UIView.AnimationOptions.curveLinear option do in a UIView animation?
AStarts the animation slowly and speeds up at the end.
BAnimates the view at a constant speed from start to finish.
CStarts the animation quickly and slows down at the end.
DRepeats the animation indefinitely.
Step-by-Step Solution
Solution:

  1. Step 1: Understand animation curve types

    Animation curves control the speed of the animation over time. curveLinear means the speed is constant.

  2. Step 2: Match the option to behavior

    curveLinear animates at a steady pace without speeding up or slowing down.

  3. Final Answer:

    Animates the view at a constant speed from start to finish. -> Option B

  4. Quick Check:

    Animation curve linear = constant speed [OK]
Quick Trick: Linear curve means steady speed throughout animation [OK]
Common Mistakes:
  • Confusing linear with ease-in or ease-out curves
  • Thinking linear repeats animation
  • Assuming linear slows down at the end
