Initialize NSArray with floats?

Question

Is this a valid way to initalize an NSArray with float objects?

NSArray *fatArray = [NSArray arrayWithObjects:
                    [NSNumber numberWithFloat:6.9]         


        

Answer 1

If you're going to be creating a lot of these arrays with exactly the same number of elements, you could define a FloatArrayFactory class that implements something like:

+ (NSArray *) arrayWithFloat: (float)f;
+ (NSArray *) arrayWithFloat: (float)f1 and: (float)f2;
+ (NSArray *) arrayWithFloat: (float)f1 and: (float)f2 and: (float)f3;
+ (NSArray *) arrayWithFloat: (float)f1 and: (float)f2 and: (float)f3 and: (float)f4;

And if that's too verbose, you could go for the terse and funky look of unnamed parameters:

+ (NSArray *) arr: (float)f1 : (float)f2 : (float)f3;

which you can call like this:

NSArray *a = [Factory arr: 1.0 :2.0 :3.0 :4.0];
