UILabel itself cannot draw a label with different attributes/fonts within the text. But Core Text can. You can create a subclass of UILabel that wraps an attributed string and uses Core Text to draw it. You can handle the drawing as in this sample code from the Core Text programming guide:

// Build up your attributed string, then...
CTLineRef line = CTLineCreateWithAttributedString(attrString);

// Set text position and draw the line into the graphics context
CGContextSetTextPosition(context, 10.0, 10.0);
CTLineDraw(line, context);
CFRelease(line);
