Look Up Documentation

Xcode gives you access to ADC Reference Library content. You can jump directly to documentation and header files while you work on a project. Try it out:

1. Open ConverterController.java in an editor window.

2. Option–double-click the word setFloatValue in the code. (Hold down the Option key and double-click the word.) The Developer Documentation window appears with a list of relevant method names in its detail view. The Java language version of setFloatValue in NSCell is highlighted in the detail view, and its associated HTML-formatted documentation appears in the content pane. This reference-library access system provides a fast way to get to reference material. Read more in “Expanding on the Basics.”

3. Close the Developer Documentation window.

4. Command–double-click the same word. A pop-up menu with a list of method names appears.

5. Choose [NSCell setFloatValue]. This time, Xcode jumps to the method declaration in the associated Objective-C header file.

6. Close the header file.
