Answer / babu
A singleton class is a special kind of class where only one instance of the class exists for the entire application. (In the case of an iPhone app, the one instance is shared across the entire app.) Some examples in UIKit are [UIApplication sharedApplication] (which returns the sole instance of the application itself), and [NSFileManager defaultManager] (which returns the file manager instance). Singletons can be an easy way to share data and common methods across your entire app.
