Objective-C managed a jump of 3.91% to 6.92% in 2011, and is now only a percent or so shy of C++ (8.06%), which incidentally just got edged out by C# (8.78%). It also zoomed ahead of Python (3.22%), which squeaked by Objective-C just barely last year to take top honors, but has now fallen below PHP and Visual BASIC.
Ruby, Perl and JavaScript are in the 1-3% range.
As TIOBE doesn't appear to keep old posts around the above link is likely to go stale in about a month. Here is the table:
