No one likes limitations. Though Apple has been opening up more and more of their API with each software update, a good chunk of it is still off limits to anyone outside of their own team of developers. Be it because they’re unstable, unproven, or just outright blacklisted, a number of methods exist that no one but Apple is supposed to use.
Of course, people try to use them anyway. Some (like Google) succeed. Others don’t. The practice of playing with verboten methods is heavily frowned upon - but if a newly discovered private method is any indication, Apple’s at least got a sense of humor about it.
