* Use NS_DECL_RUNNABLEMETHOD_ macros to declare a runnable class for the given
* method of the given class. There are three macros:
* NS_DECL_RUNNABLEMETHOD(Class, Method)
* NS_DECL_RUNNABLEMETHOD_ARG1(Class, Method, Arg1Type)
* NS_DECL_RUNNABLEMETHOD_ARG2(Class, Method, Arg1Type, Arg2Type)
* Note Arg1Type and Arg2Type must be types which keeps the objects alive.
*
* Use NS_DISPATCH_RUNNABLEMETHOD_ macros to create an instance of declared
* runnable class and dispatch it to main thread. Availabe macros are:
* NS_DISPATCH_RUNNABLEMETHOD(Method, Object)
* NS_DISPATCH_RUNNABLEMETHOD_ARG1(Method, Object, Arg1)
* NS_DISPATCH_RUNNABLEMETHOD_ARG2(Method, Object, Arg1, Arg2)
