Deprecated UIViewController Methods. A Boolean value indicating whether the view should underlap the status bar.
(Deprecated in iOS 7.0.) Discussion When a view controller presents its view, it normally shrinks that view so that its frame does not overlap the device’s status bar. Setting this property to YES causes the view controller to size its view so that it fills the entire screen, including the area under the status bar. (Of course, for this to happen, the window hosting the view controller must itself be sized to fill the entire screen, including the area underneath the status bar.)
If this property is YES, the view is not resized in a way that would cause it to underlap a tab bar but is resized to underlap translucent toolbars. The default value of this property is NO, which causes the view to be laid out so it does not underlap the status bar. ARC. By Paul on September 7th, 2011 in TechnobabbleTags: arc, development, iOS, ios5, xcode Automatic Reference Counting (ARC) largely removes the burden of manual memory management, not to mention the chore of tracking down bugs caused by leaking or over-released objects!
Despite its awesomeness, ARC does not let you ignore memory management altogether. This post covers the following key aspects of ARC to help you get up and running quickly.

What Has Changed? In the time before ARC, you had to manually retain/release/autorelease objects to ensure they would “stick around” for as long as you needed them.
Let’s start at the beginning … Reference Counted Memory: Quick Review Enabling ARC in Your Project 1. 2. Storyboard. Background Info (Not Necessary Reading): I read a 500 page book on Objective-C on Saturday and so I thought I was ready to start programming iPhone apps, so then I looked at a ton of books and tried to do the step-by-step tutorials but none of them made any sense since Apple has updated all of their development tools and there are a lot of new features that have made things in the past irrelevant.
For example, XIB files were not automatically generated in the newest version of XCode, so it was a struggle to get even a simple program running. I didn't even know how to design a user interface, so being confused I naturally Googled the file in XCode that I didn't know what is was (storyboard) and I saw that it was Apple's new way to design user interfaces.
Background Info (Required): Interface builder is a user interface design tool in XCode 4 where you can drag and drop objects from the side bar, and have them saved in a XIB (pronounced "zib") or a NIB file.

Thanks for visiting! This is the second iOS 5 tutorial in the iOS 5 Feast ! This tutorial is a free preview chapter from our new book iOS 5 By Tutorials . Matthijs Hollemans wrote this chapter – the same guy who wrote the iOS Apprentice Series . Storyboarding is an exciting new feature in iOS 5 that will save you a lot of time building user interfaces for your apps. You may not know exactly yet what the app does but you can clearly see which screens it has and how they are related. If you have an app with many different screens then storyboards can help reduce the amount of glue code you have to write to go from one screen to the next.
Storyboards have a number of advantages over regular nibs: With a storyboard you have a better conceptual overview of all the screens in your app and the connections between them. Getting Started : Ratings : iPhone. iOS 5. 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. 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.
