To create a NSUserActivity object, your app must declare the types of activities it supports in its Info.plist file. Supported activities are defined by your application and should be unique. An activity is defined using a reverse-domain style naming scheme (i.e. "com.companyName.productName.ac...

There are three different properties for styling list-items: list-style-type, list-style-image, and list-style-position, which should be declared in that order. The default values are disc, outside, and none, respectively. Each property can be declared separately, or using the list-style shorthand p...

For example without a barrel, a consumer would need three import statements: import { HeroComponent } from '../heroes/hero.component.ts'; import { Hero } from '../heroes/hero.model.ts'; import { HeroService } from '....

Here the simplest recursive function over list type. This function only navigate into a list from its start to its end and do nothing more. -spec loop(list()) -> ok. loop([]) -> ok; loop([H|T]) -> loop(T). You can call it like this: loop([1,2,3]). % will return ok. Here the ...

Like list, simplest function over iolist and bitstring is: -spec loop(iolist()) -> ok | {ok, iolist} . loop(<<>>) -> ok; loop(<<Head, Tail/bitstring>>) -> loop(Tail); loop(<<Rest/bitstring>>) -> {ok, Rest} You can call it like this: lo...

Recursive function use their states to loop. When you spawn new process, this process will be simply a loop with some defined state.

Here 2 examples of recursive anonymous functions based on previous example. Firstly, simple infinite loop: InfiniteLoop = fun R() -> R() end. Secondly, anonymous function doing loop over list: LoopOverList = fun R([]) -> ok; R([H|T]) -> R(T) end. These two func...
