The LoadFromFile function is deprecated, you should use other functions for loading from file.
Can you open the xcode log and see exactly what crashes it?

i don’t run by xcode . because i stuck this problem(http://answers.unity3d.com/questions/22275/xcode-build-and-archive-error-no-such-file-or-dire.html)

you said loadfromfile is deprecated.
please say other file loading method for ios.
thanks… T_T

You could use for example System.IO.File.ReadAllBytes.
Make sure you are using .Net 2.0 or higher (that function requires .Net 2.0).

Ok, but make sure that you use the .bytes extension, not .txt or similar. Otherwise unity will scramble the zip data (described more here: http://arongranberg.com/astar/docs/save-load-graphs.php)
