Sadly Eclipse ships with a broken color theme when it comes to autocompletion and tooltips. I cannot tell if the problem is limited to Ubuntu Precise, however, it is worth getting fixed immediately. The following screenshots illustrate the broken color settings in both situations. The tooltip window shows up with a black background color and blue links.

This post describes how you can to setup a custom NSLog snippet in Xcode 4. By default, this custom NSLog prints the class and method name of the position it is inserted.

NSLog auto completion

Please follow these steps to add the code snippet to the scripts in Xcode 4.

1. Copy and paste the following code into your editor. Anywhere.
   NSLog(@"%@ %@", self.className, NSStringFromSelector(_cmd)); /* DEBUG LOG */
2. Open up the code snippets library which sits in the utility pane on the right side. Look for the curly braces {}.
3. Highlight the above mentioned code – click and hold the mouse over the text  (for a short while) – drag them into the code snippet library.
4. Afterwards you can edit the snippet and add a title, summary and a completion shortcut. I used the following settings:

                 Title: Custom NSLog (Class & method name)
               Summary: NSLog prints the class and method name
              Platform: All
              Language: Objective-C
   Completion Shortcut: NSLog
     Completion Scopes: All
