How can I display documentation in Xcode via CodeSense?

autocomplete, codesense, javadoc, objective-c, xcode

Solution

It's not quite the same, but the close equivalent is Quick Help, accessible from the Help Menu. It's a floating palette that dynamically shows a quick documentation for the method or class at your cursor position.

Problem

I am Java developer and would like to know how I can get the equivalent of a JavaDoc in Xcode when CodeSense is doing its auto-complete? If I hit the ESC button I can get a list of methods etc. but it does not show me the descriptions of what the methods do.
