Join Todd Perkins for an in-depth discussion in this video Unique concepts in iOS, part of Building a Note-Taking App for iOS 7.
…Here are some items that are unique to iOS.…First, the way that iOS, screens are organized.…Each screen that you view is known as a scene.…And scenes are organized into storyboards.…Each screen has various UI elements, and X-code gives you a visual…interface, for laying out these elements to create the screens for you app.…There are a few differences between phone and…tablet devices that you should be aware of.…
First, is of course, the aspect ratio.…That also includes the number of pixels on the screen.…And in some cases you'll find, alternate UI elements.…And so of course, some UI elements are shared, but the…great thing about X-code and using Apple's built-in tools is that,…most of the code is the same between a tablet version,…of a UI element and a phone version of the UI element.…So you have to do very little.…To account for that yourself.…As far as graphics go in an application,…all of your assets are stored as resources.…
Resources for an app, are not actually file system folders.…So, when you have resources for your application.…
These courses take you through building a complete mobile app from scratch; this installment uses the iOS SDK and Xcode to get the job done.
