How to declare an array of floats as a class variable in Objective-C when the dimension is undefined at the class instantiation time?

Question

In Java, it would look like this:

class Foo
{
  float[] array;
}

Foo instance = new Foo();
instance.array = new float[10];

Here's another way to do it. Create a NSMutableArray object and add NSNumber objects to it. It's up to you to decide whether or not this is sensible.

NSMutableArray *array;
array = [[NSMutableArray alloc] init];
[array addObject:[NSNumber numberWithFloat:1.0f]];
[array release];
