dispatch_once execute code once

dispatch_once execute code once | iPhone and iPad development | Scoop.it

There’s dispatch_sync to do some work synchronously. There’s also dispatch_once that’s used to guarantee that something happens exactly once, no matter how violent the program’s threading becomes. It’s actually a very simple idiom:

static dispatch_once_t onceToken; dispatch_once (&onceToken, ^{ // Do some work that happens once });
Vincent Demay's insight:

A good article to understand dispatch_once

ADLivelyCollectionView: let you add custom animations to any UICollectionView.

ADLivelyCollectionView: let you add custom animations to any UICollectionView. | iPhone and iPad development | Scoop.it

ADLivelyCollectionView is a drop-in subclass of UICollectionView that lets you add custom animations to any UICollectionView.

This is the port of ADLivelyTableView, one of our most starred libraries on GitHub, to UICollectionView.

It's rather simple to use :

  • Add ADLivelyCollectionView.h and ADLivelyCollectionView.m to your iOS project
  • Link against the QuartzCore framework if you don't already
  • Turn any UICollectionView you want to animate (or subclass thereof) into a subclass of ADLivelyCollectionView
  • Pick whichever animation you like, like this :livelyCollectionView.initialCellTransformBlock = ADLivelyTransformFan;

You can also write your own initial transform block.

Canvas: Animate in Xcode without code

Canvas: Animate in Xcode without code | iPhone and iPad development | Scoop.it

Canvas is a project to simplify iOS development for both designers and developers. It had been difficult for designers to get hands on building the product with the lack of objective-c and Xcode experience, and a hard time for developer to use reasonable amount of time and lines of code just to achieve really simple effects.


With Canvas, creating stunning animations requires zero lines of code, trendy effects like the Parallex headers, Sticky sections, Blurred Backgrounds, will be as simple as few lines of code changes.
