Objective-C Singleton Class template
The Singleton design pattern is widely spread when developing software with the Cocoa (touch) framgework. A Singleton makes sure, that only one object of your class is allocated.
When using the template a cocoa class file with 2 additions will be generated:
-a static pointer to the singleton object
-a static method to access the singleton object: shared<<CLASSNAME>>

Usage:
Just choose the template “Objective-C Singleton class” when adding a new file to your project. To access the singleton object don’t allocate the object yourself. Use the static method “shared…” (e.g: sharedTestManager):
TestManager *myTestManager = [TestManager sharedTestManager];
