Is there a simple efficient way to initialize a NSArray with a C array of doubles (converting them to NSNumbers in the process)? [...]


Oh... I completely missed the chance of mentioning CocoaSTL...

   double src[] = { ... };
   NSMutableArray* dst = ...;

   std::transform(beginof(src), endof(src), back_inserter(dst),
      unary_method<double>("numberWithDouble:")([NSNumber class]));

While "simple" here can be questioned, but it's short and avoids the loop ;) -- http://macromates.com/ ::: TextMate, OS X text editor http://macromates.com/sigpipe/ ::: Personal weblog about programming
