Makes the receiver the key window and makes that window visible.

This is a convenience method to make the receiver the main window and displays it in front of other windows. You can also hide and reveal a window using the inherited hidden property of UIView.

This method call performs a critical function. If you omit it then the top level view to the window will not be autoresized however you have set the springs and struts. Took me a while to figure that out: if the in-call status bar resizing is not happening, check to see that the window is marked as key.

The key window is the window which will receive user interaction.

This means that this is the window that accepts keyboard input. This matches similar nomenclature on Mac OS X.
