25. Interface Design
There’s 2 ways to design your UI
Interface builder & Storyboards
Code

26. Interface Design with Storyboards
+
Quickly set a UI
Straightforward impl. for small apps
≠ XIBs for ≠ localizations
Adjust the layout
Difficult to merge conflicts in a team environment
Impossible to describe dynamic views
XIBs lack customizations
Harder to debug

27. Interface Design with IB & Story

28. Interface Design with IB & Story
Demo
Creating a simple app w/ storyboard

29. Interface Design with code
+
Easier to merge conflicts and diff lines of code than it is a XIB file
Trace code in debug mode / defensive programming
Faster view creation
More control
Visualize the UI
More time to layout your views

30. Interface Design with code
//---- Create red rect UIView
!
CGFloat width = self.view.bounds.size.width;
//Grab width of main (blue) view
CGFloat height = self.view.bounds.size.height; //Grab height of main (blue) view
UIView *infoPanel = [[UIView alloc]initWithFrame:
CGRectMake(width*0.02, height*0.84, width*0.96, height*0.15)];
infoPanel.backgroundColor = [UIColor redColor];
!
!
[self.view addSubview:infoPanel];
//---- AutoLayout methods goes here !

31. Interface Design
So… what should I use ?

32. Interface Design
No fixed answer !
Multiple factors
Team project or alone cowboy?!
How much time do you have ?!
Have you a precise idea of your UI ? !
If team, is there a designer in it ?
