Question

I’m trying to do custom drawing & I’ve created a custom colour:

fawYellowColour = [UIColor colorWithRed: (255.0/255.0 ) green: (221.0/255.0) blue: (0.0/255.0) alpha:1.0];

I now want to use my custom colour to draw, I expected I could simply replace the preset colour with my custom fawYellowColour like this:

CGContextSetFillColorWithColor(ctx, [UIColor fawYellowColour].CGColor);

However I get the message –

error: request for member ‘CGColor’ in something not a structure or union

Any ideas? thanks in advance 🙂

You’ve created a variable called fawYellowColour. Then you try and send the message -fawYellowColour to UIColor, expecting a valid result. You should be getting a warning saying that this method doesn’t exist. What you really want to say is

CGContextSetFillColorWithColor(ctx, fawYellowColour.CGColor);
