Interface Design

There’s 2 ways to design your UI

CodeInterface builder & Storyboards

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

Interface Design with IB & Story

Interface Design with IB & Story

DemoCreating a simple app w/ storyboard

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

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 !

Interface Design

So… what should I use ?

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 ?
