cs193p – Lecture #5 – View Controller Lifecycle

Please note, this blog entry is from a previous course. You might want to check out the current one.

Lecture #5 starts with an introduction to text views and – new to iOS 7 – text storages and TextKit followed by a short demo.

The view-controller life cycle consists of the following steps:

  • the view gets instantiated e.g. from storyboard
  • awakeFromNib is called, which you could compare to init
  • the outlets get set
  • viewDidLoad is called, which can be used for basic setups
  • geometry is determined
  • viewWillLayoutSubviews and viewDidLayoutSubviews are called

  • viewWillDisappear and viewDidDisappear are called
  • didReceiveMemoryWarning is called when memory gets low

cs193p – Lecture #4 – Foundation and Attributed Strings

Please note, this blog entry is from a previous course. You might want to check out the current one.

Lecture #4 is mostly theory with a tiny demonstration in between.

It starts with an introduction to foundation objects and how to create them using initializers or special class methods. The demo shows how to use introspection to safely use dynamic typing.

Further objects of the foundation framework explained during the lecture are mutable and immutable arrays (as well as enumeration), numbers, values, data objects, dates, sets (ordered, unordered), and dictionaries.

New for iOS 7 is preferredFontForTextStyle for fonts and font descriptors.

The lecture ends with attributed strings …

The code for this lecture is available at github.

The lecture as well as its slides are available via iTunes called “4. Foundation and Attributed Strings”.
