#Stay Standalone

A short script to prevent internal links to a "webapp" added to iPhone home screen to open in Safari instead of navigating internally.

Hacking UIView animation blocks for fun and profit

In this article, I'm going to explore a way that we can create views that implement custom Core Animation property animations in a natural way.

As we know, layers in iOS come in two flavours: Backing layers and hosted layers. The only difference between them is that the view acts as the layer delegate for its backing layer, but not for any hosted sublayers.

In order to implement the UIView transactional animation blocks, UIView disables all animations by default and then re-enables them individually as required. It does this using the actionForLayer:forKey: method.

Somewhat strangely, UIView doesn't enable animations for every property that CALayer does by default. A notable example is the layer.contents property, which is animatable by default for a hosted layer, but cannot be animated using a UIView animation block.

To run on ios:

Install XCode (recommended) or XCode command line tools by xcode-select --install
Into XCode settings, go to "Downloads" tab and download iOS 9.2 emulator
Compile native app and run it on simulator via npm run ios

To run on Android:

Set up Android environment
Create emulator via npm run android-emulator-create
Run emulator via npm run android-emulator
Compile native code and run it on emulator via npm run android

	// by the way, you need to logout and log back in for this to take effect. Or at least that's what
	// Quartz Debug says. Who knows, maybe it's lying?

	// P.S. Go to [Apple menu --> System Preferences --> Displays --> Display --> Scaled] after logging
	// back in, and you'll see a bunch of "HiDPI" resolutions in the list to choose from.
