PDF creation on iPhone: <Error>: invalid Type1 font: unable to stream font

Question

Hi!

I'm creating a PDF on the iPhone and this works almost brilliant. I just get one annoying error in the console when I draw text:

<Error>: invalid Type1 font: unable to stream font

I'm using the following code to do the text drawing:

[title drawInRect:textRect withFont:[UIFont fontWithName:@"Helvetica-Bold" size:16]];

I've tried out several fonts:

• Times-Roman
• Helvetica
• Courier
• Times-Bold
• Helvetica-Bold
• Courier-Bold

But I get the error for each of these fonts. What's wrong?
