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 have a lot of floats to convert, or want to paste them in from a comma separated list, it may be easier to call a function that converts floats into an NSArray instance.

NSArray*  arrayFromFloats(NSUInteger count, float *floats)
{
    NSMutableArray* ma = [NSMutableArray arrayWithCapacity:count]; 
    NSUInteger i; 
    for (i=0; i

Example caller:

static float floats[] = {1.1, 2.2, 3.3}; 
NSUInteger count = sizeof(floats)/sizeof(float);
NSArray* a = arrayFromFloats(count, floats);
