How does typedef-ing a block works

Question

In C/Obj-C, we do a typedef like this typedef int MYINT; which is clear.

Doing typedef for a block -typedef void (^MyBlock) (int a);

No

Answer 1

Also from "Blocks Programming Topics", creating a type for blocks should be like this:

typedef returnType (^blockName)(argument1, argument2, ...)

Below is a very simple practical example:

typedef float (^MyBlockType)(float, float);
MyBlockType AddTwoFloat = ^(float a, float b) {return a + b;};
MyBlockType MultiplyTwoFloat = ^(float a, float b) {return a * b;};
float c = AddTwoFloat(1, 2); //c = 3
float d = MultiplyTwoFloat(1, 2); //d = 2
