Application lifecycle is an important part of any software development project, even more so in Windows 8.
Windows 8 introduces three distinct states : Running, Not Running, and Suspended.
Transitioning between these states is important, as is saving data when transitioning to ensure a consistent experience across all devices.
In this video, I will go over application lifecycle in Windows Runtime, and will show you how to configure the SuspensionManager class.

The NavBar or the navigation bar is the top side view that appears by default over our main view if we have a navigation controller presenting the corresponding view controller.
Its dimensions for iPhone and iPod touch are 320 x 44, so if we want to set custom background images for that, we need 2 images: one normal of 320 x 44 pixels, and the other one for Retina Display, of 640 x 88 pixels.
iOS provides us 4 default options for customising the NavBar, and we do that by writing the following line of code:
self.navigationController.navigationBar.barStyle = UIBarStyleDefault;
The barStyle property can be set to one of 4 values, which are:
UIBarStyleDefault,
UIBarStyleBlack,
UIBarStyleBlackOpaque,
UIBarStyleBlackTranslucent.
Starting with iOS 5, it is very easy to set a background image for the NavBar in this way:
UIImage *navBarImage = [UIImage imageNamed:@nav-bar-image];
[[UINavigationBar appearance] setBackgroundImage:navBarImage forBarMetrics:UIBarMetricsDefault]; How to customize the NavBar in iOS](https://i.ytimg.com/vi/kjQ4qVGHr9w/mqdefault.jpg)
