Howdy howdy, NSHipsters!

If you alloc init an NSCalendar, you'll notice that New Year's Eve falls on a Monday this year, a.k.a. "the day NSHipster is published every week". What fun!

So in celebration of the upcoming year++, I thought it'd be fun to compile a list of some of your favorite tips and tricks of the trade. Submit your favorite piece of Objective-C trivia, framework arcana, hidden Xcode feature, or anything else you think is cool, and you could have it featured in the year-end blowout article. Just comment on this gist below!

Here are a few examples of the kind of things I'd like to see:

	/// DO CHANGE
	///
	self = [super init];
	if (self == nil) {
	return nil;
	}

	///
	self = [super init];
	if (self == nil) return nil;

	Ну условно говоря:
	Модеь: АААА! Давление 1960 на 1230!!!
	Viewmodel : состояние лампочки: красное
	View; Окей, отобразим ! красным


	# и в обратную сторону
	(Пользователь жмет педальку)
	View : -> ViewModel
	Слушай, тут пользователь жмякнул педальку.
