Note

Apple will reject apps that are using private url schemes (Ugh, Apple....) if they are pretty much obvius. Some apps are rejected and others are not, so, be aware of this issue before implementing any of those URL's in your app as a feature.

Updates

• [UPDATE 4] iOS 10 update: apparently settings now can be reached using App-Pref instead of prefs
• [UPDATE 3] For now you just can use url schemes to open your apps's settings with Swift 3.0 (Xcode 8). I'll keep you informed when OS preferences can be reached
• [UPDATE 2] The openURL() method of UIApplication is now deprecated. You should use application(_:open:options:) instead
• [UPDATE 1] Not yet tested in iOS 10. It will fail because of policies changes in URL scheme handling.

Generic 1,2,3 Noise

float rand(float n){return fract(sin(n) * 43758.5453123);}

float noise(float p){
	float fl = floor(p);
  float fc = fract(p);
	return mix(rand(fl), rand(fl + 1.0), fc);

1. The Layer Tree

Core Animation's original name is Layer Kit

Core Animation is a compositing engine; its job is to compose different pieces of visual content on the screen, and to do so as fast as possible. The content in question is divided into individual layers stored in a hierarchy known as the layer tree. This tree forms the underpinning for all of UIKit, and for everything that you see on the screen in an iOS application.

In UIView, tasks such as rendering, layout and animation are all managed by a Core Animation class called CALayer. The only major feature of UIView that isn’t handled by CALayer is user interaction.

There are four hierarchies, each performing a different role:

• view hierarchy
• layer tree

기술 문서를 쓸 때 주의해야 할 몇 가지

텍스트 파일의 장점

자신이 하는 일이 소모적인 일회성의 일이 아니라고 여긴다면 위키에 글을 작성해서 보편적인 방식으로 공유하라. 글을 읽고 의문이 생기는 것에 대한 토론은 글 안에서 이루어지는 것이 좋다. 중요한 정보를 위키 혹은 RCS, Git 등으로 관리되는 텍스트가 아닌, 워드, 파워포인트 등의 이진 문서로 작성해서 올릴 때마다 당신의 동료는 그 정보에 대한 접근성, 가시성, 버전 관리 문제로 고통을 겪을 것이다.

명징한 소재

잡다한 소재가 하나의 글에 다 들어가 있으면 재활용성, 접근성, 발전 가능성이 떨어진다. 자기완결적인 항목들로 페이지를 나눔으로써 정보로서의 가치가 더 커진다. 나중에 나눌 의향으로 일단 쓰고 보는 것은 환영한다. 고민 하면서 글쓰기를 미루는 것보다는 일단 쓰는 것이 중요하다.
