Drawing Text with Core Graphics

Question

I need to draw centered text to a CGContext.

I started with a Cocoa approach. I created a NSCell with the text and tried to draw it thus:

NSGraphicsConte         


        

Answer 1

I would continue with your above approach but use NSAttributedString instead.

NSGraphicsContext* newCtx = [NSGraphicsContext graphicsContextWithGraphicsPort:bitmapContext flipped:true];
[NSGraphicsContext saveGraphicsState];
[NSGraphicsContext setCurrentContext:newCtx];
NSAttributedString *string = /* make a string with all of the desired attributes */;
[string drawInRect:locationToDraw];
[NSGraphicsContext restoreGraphicsState];
