xcode

The following tools is provided by Apple

dlopen
dlsym
objc_getClass
sel_registerName
objc_msgSend

Those are listing Objective-C selectors, or strings. Objective-C selectors are stored in a special region of the binary, and therefore Apple could extract the content from there, and check if you've used some undocumented Objective-C methods.

How to utilize these tools to find undocumented Objective-C methods?

EDIT: Recently, one of my App rejected due to using one undocumented methods.

-[UIDevice setOrientation]

Since, selectors are independent from the class you're messaging, even if my custom class defines -setOrientation: irrelevant to UIDevice, there will be a possbility of being rejected.
