Coworking w Krakowie

Update 28.04.2018

Otworzyło się ostatnio tyle nowych coworków, że nie nadążam tego odwiedzać :) Będę się starał stopniowo aktualizować listę, w międzyczasie polecam przeglądnąć komentarze pod postem. (Nie chcę szczerze mówiąc przenosić tego do jakiegoś bardziej zorganizowanego repozytorium, bo chcę, żeby to pozostało takim moim osobistym nieobiektywnym review tych coworków - ciężko byłoby uzgadniać, czy w danym miejscu jest głośno, albo czy jest fajna atmosfera... W razie wątpliwości, post jest dostępny na licencji WTFPL :)

/**
 Provides the ability to verify key paths at compile time.
 
 If "keyPath" does not exist, a compile-time error will be generated.
 
 Example:
    // Verifies "isFinished" exists on "operation".
    NSString *key = SQKeyPath(operation, isFinished);
 
    // Verifies "isFinished" exists on self.

This gist outlines how to resize a view when a keyboard appears using Auto Layout (there are a bunch of code samples out there that manually adjust the view's frame, but that's just so 2013). The method I outline below works universally on both iPhone and iPad, portrait and landscape, and is pretty darn simple.

Setting Up

The first thing to do is to define our containing view controller, the view, and the bottom constraint that we'll use to adjust its size.

Here's HeightAdjustingViewController.h. We don't need to expose any public properties, so it's pretty bare.

This template let's you easily implement a property getter like this:

- (UIView *)myView {
	if (!_myView) {
		_myView = [UIView new];
	}
	return _myView;
}
