iOS Developer Library. View Programming Guide for iOS: Views. Because view objects are the main way your application interacts with the user, they have many responsibilities. Here are just a few: This chapter focuses on the steps for creating, managing, and drawing views and for handling the layout and management of view hierarchies. For information about how to handle touch events (and other events) in your views, see Event Handling Guide for iOS.
Creating and Configuring View Objects You create views as self-contained objects either programmatically or using Interface Builder, and then you assemble them into view hierarchies for use. Creating View Objects Using Interface Builder The simplest way to create views is to assemble them graphically using Interface Builder. You usually create nib files in order to store an entire view hierarchy for one of your application’s view controllers. When using nib files with a view controller, all you have to do is initialize the view controller with the nib file information. Creating View Objects Programmatically. Development Videos. Create Apps for iOS 6. iOS 7 SDK and Xcode 5 To build your apps for iOS 7, make sure your devices are running iOS 7 and your Mac has Xcode 5 with iOS 7 SDK installed. If you don’t have the latest release of Xcode, you can download it from the Mac App Store.
Xcode Release Notes A7 and 64-bit iPhone 5s, iPad Air, and iPad mini with Retina display are powered by Apple’s next generation A7 chip, making them the world’s first mobile devices with 64-bit desktop-class architecture for blazing fast performance in the palm of your hand. The iOS kernel, libraries, and drivers now take advantage of 64-bit, delivering up to 2x faster CPU and graphics performance for your apps and games. OpenGL ES 3 You can now create apps and games that look and perform better than ever with built in support for the latest version of OpenGL ES, version 3. M7 and Core Motion Leveraging the new M7 motion coprocessor, the Core Motion framework is updated to support step counting and motion tracking.
