Core Animation

  • Pros
    • Easy to do simple animation properties (alpha, position) with good options (reversing, repeating, delaying)
    • Great performance
  • Cons
    • Need to know C API to do more powerful things
    • C API isn't ARC - need to understand memory management
  • Performance Considerations
    • Layer creation - CALayer is expensive to new up.
    • UIBezierPath for shadowpaths - compositing alpha channel for shadow generation is expensive, can you create your own shadowPath
    • UIView block-based animation - Setting things in completion block rather than signing up for delegation.
