In simulator i will get the obj files from bundle:
NSArray *myArray = [[NSBundle mainBundle] pathsForResourcesOfType:@"obj" inDirectory:nil];
In simulator the obj files are printed alphabetical order:
/Users/name/Library/Application Support/iPhone Simulator/6.0/Applications/10FF2D60-7B33-4AE9-9CA2-95A951A55C49/3DModels.app/**banana.obj**,
/Users/name/Library/Application Support/iPhone Simulator/6.0/Applications/10FF2D60-7B33-4AE9-9CA2-95A951A55C49/3DModels.app/**plane3.obj**,
/Users/name/Library/Application Support/iPhone Simulator/6.0/Applications/10FF2D60-7B33-4AE9-9CA2-95A951A55C49/3DModels.app/**wolverine.obj**,
/Users/name/Library/Application Support/iPhone Simulator/6.0/Applications/10FF2D60-7B33-4AE9-9CA2-95A951A55C49/3DModels.app/**Wteapot.obj**,
/Users/name/Library/Application Support/iPhone Simulator/6.0/Applications/10FF2D60-7B33-4AE9-9CA2-95A951A55C49/3DModels.app/**XBODY.obj**,

)
But ipad the obj files are not printed alphabetical order.
/Users/name/Library/Application Support/iPhone Simulator/6.0/Applications/10FF2D60-7B33-4AE9-9CA2-95A951A55C49/3DModels.app/**wolverine.obj,**

What is the problem?
I think some of your obj file name starting character is in capital letter. just change those file names starting character is in small letter.
