Created June 3, 2011 18:43
Using `dispatch_after` to update UI regularly
// clang -framework Foundation dispatch_after_example.m -o dispatch_after_example
// Compiling with gcc requires separating declaration of b from assignment,
// but you can omit the -framework flag for GCC.
/* @author Jeremy W. Sherman
* @date 2011-06-03
*
* Demonstrates use of a recursive block to set up a repeating action
* using `dispatch_after()`.
* Assumes 10.6+ or iOS with GCD and blocks (whichever version that was).

Created September 24, 2012 19:08
Converting a std::vector into an NSArray
//clang++ -std=c++11 -stdlib=libc++ -framework Foundation nsarray.mm -o nsarray
/* Note:
* - libstdc++ has been frozen by Apple at a pre-C++11 version, so you must opt
for the newer, BSD-licensed libc++
* - Apple clang 4.0 (based on LLVM 3.1svn) does not default to C++11 yet, so
you must explicitly specify this language standard. */
