This still the longest one or has Apple outdone themselves since? 11

That's still the longest, both by name length (148) and number of
arguments, if you look only at the most commonly used frameworks.
However, as of Leopard, the longest *documented* method name (150,
though with only 9 arguments) is
[QCPlugInContext
outputImageProviderFromBufferWithPixelFormat:pixelsWide:pixelsHigh:baseAddress:bytesPerRow:releaseCallback:releaseContext:colorSpace:shouldColorMatch
:]

I also found two undocumented methods with 15 arguments, both in
DOMMouseEvent:
initMouseEvent:canBubble:cancelable:view:detail:screenX:screenY:clientX:clientY:ctrlKey:altKey:shiftKey:metaKey:button:relatedTarget
:
initMouseEvent:::::::::::::::
On the iPhone [2], the longest by name (113), with 6 arguments, is
[NSDecimalNumberHandler
decimalNumberHandlerWithRoundingMode:scale:raiseOnExactness:raiseOnOverflow:raiseOnUnderflow:raiseOnDivideByZero
:]
Until recently, the method with the most arguments (7) was
[NSString
drawAtPoint:forWidth:withFont:minFontSize:actualFontSize:lineBreakMode:baselineAdjustment
:]
In the 3.0 SDK there is now
[NSMigrationManager
migrateStoreFromURL:type:options:withMappingModel:toDestinationURL:destinationType:destinationOptions:error
:]
with 8 arguments.
