How do I make an array of CGFloats in objective c?

You can only add objects to an NSArray, so if you want you add CGFloats to an array, you can use NSNumber.

Eg:

NSNumber * aNumber = [NSNumber numberWithFloat:aFloat];

Then to get it back:

CGFloat aFloat = [aNumber floatValue];

iphone objective-c arrays cgfloat

CGFloat i.e. primitive arrays can be constructed like so...

CGFloat colors[] = { 1, 0, 0, 1 };

and subsequently "used" in a fashion similar to...

CGContextSetFillColor(context, colors);

OR (more concisely, via casting)...

CGContextSetFillColor(context, (CGFloat[]){ 1, 0, 0, 1 });
