Question

This is the code i have:

CGFloat buttonGradient1Colors [] = { 
        [gradient1TopColor ], 1.0, 1.0, 0.16,
        0.0, 0.0, 0.0, 0.11
    };

But i want to add an if statement, where the float changes it’s value based on something, and so i need to set up the CGFloat beforehand. I tried:

CGFloat buttonGradient1Colors;

and

CGFloat buttonGradient1Colors [];

but the second one gave me an error on the line, and the first one gave me an error further on. Any ideas?

EDIT:

So now i have this:

CGFloat buttonGradient1Colors [8];

    buttonGradient1Colors [8] = { 
        1.0, 1.0, 1.0, 0.16,
        0.0, 0.0, 0.0, 0.11
    };

but it’s giving me an ‘expected expression’ error on the 2nd line.

Answer 1

You have to specify the size when you creating a C array.

If you want to change the value. You can do like this

CGFloat buttonGradient1Colors[8] = {1.0, 1.0, 1.0, 0.16, 0.0, 0.0, 0.0, 0.11};
if (condition)  {
    buttonGradient1Colors[index] = newValue;
    ...
}
