Programmatically clearing all app data (NSUserDefaults in particular)

I have an app or two for which I want a "Reset all settings" button.

I have noticed as of Yosemite or so, defaults are cached in some strange ways by OS X and from the terminal executing a defaults delete com.mycompany.myapp does not work consistently at all. I usually also need to issue a defaults write com.mycompany.app dummy dummy

I suspect this has largely to do with SandBoxing...

I want to reliably implement resetting defaults, as well as cleaning up my sandbox and cache directories.

Any ideas?

If you're doing this from within the same app whose settings you want to reset, try:

[[NSUserDefaults standardUserDefaults] removePersistentDomainForName:[[NSBundle mainBundle] bundleIdentifier]];
