objective c - forwardInvocation vs class_addMethod -

-

in implementation, have choice of using class_addmethod create new methods in runtime, or can rely on forwardinvocation/nsproxy. when both approaches available solutions, way prefer , how determine?

i prefer class_addmethod.

  1. because much faster forwardinvocation (search method list, try forwardtarget, create nsinvocation, last attempt resolve selector)
  2. it more clear add new method rather handle dynamical method call in 1 place.
