It uses keyboard shortcuts to handle starting, ending and other commands. It can also be invoked via an app-wide UIGestureRecognizer if it is to be used on the device.

Features:

• Simple to setup and use
• See the entire hierarchy (view tree) of the window
• Send messages (call any method) to the selected view during runtime
• Displays a views origin & size, including distances to edges of main window
• Displays properties of a view, including subclass properties, actions and targets (see below for an example)
• Displays accessibility properties — useful for UI automation scripts
• Move and resize view frames during runtime
• Highlighting of view frames
