22. How to develop an app One pattern to rule them all MVC Model View Controller
23. How to develop an app One pattern to rule them all Model Controller View
24. How to develop an app @interface @implementation Careful ! ViewController isn’t View & Controller! but a controller only !
25. Interface Design There’s 2 ways to design your UI Code Interface builder & Storyboards
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 ?
