So, with th...
Why would iterating over a List be faster than indexing through it?

What's going on here is you're asking the controller for the C function pointer for the method corresponding to the controller. All NSObjects respond to methodForSelector:, but you can also use class_getMethodImplementation in the Objective-C runtime (useful if you only have a protocol reference, l...
Why is the JVM stack-based and the Dalvik VM register-based?
