MonoTouch.UIKit.UIStringAttributes.set_Font bug?

guivho
Following method crashes on iPad.

    private void DrawChar (CGContext g, RectangleF frame, string c, StateType state)
    {
      var h = Convert.ToInt32 (frame.Height * .8);
      var s = new NSString (c);
      var size = MCiOS.TextSize (UIFont.BoldSystemFontOfSize (h), c.ToString ());
      var p = new PointF (frame.X + (frame.Width - size.Width) / 2, frame.Y + (frame.Height - size.Height) / 2);
      var font = UIFont.BoldSystemFontOfSize(h);
      Debug.Assert(font != null, "Failed to get font of size " + h);
      s.DrawString (p, new UIStringAttributes {
        Font = font,
        ForegroundColor = _textColors [(int)state],
      });
    }

The 'Font = font' line is painted green.

Initially I did not use the intermediate variable but changed the code
so that I could check on the font being null. Turns out it isn't: I get
{Helvetica-Bold 56}.

The details of the exception seem to indicate that it really crashes
inside MonoTouch:

System.ArgumentNullException: Argument cannot be null.

Is there some way I can prevent this error from happening?

The problem might be related to the size of the font. The same code
works fine on iphone, but of course uses a smaller fint there. (The game
draws a character in an 8x8 grid, which means cell size and thus font
size is much smaller on iphone)

The ipad runs ois 5.1.1, the iphone runs 7.0.4

This may also be important in pinpointing the bug.

If you Apple-D on the DrawString method to decompile it, you'll see
it's ios7 only

[Since (7, 0), CompilerGenerated]
public static void DrawString (this NSString This, PointF point,
UIStringAttributes attributes)
{
    This.WeakDrawString (point, attributes.Dictionary);
}

I suspect it's calling

}
    Messaging.void_objc_msgSend_PointF_IntPtr (This.Handle,
Selector.GetHandle ("drawAtPoint:withAttributes:"), point,
attributes.Handle);
}

Which is iOS7 only:

https://developer.apple.com/library/ios/documentation/uikit/reference/NSString_UIKit_Additions/Reference/Reference.html#//apple_ref/occ/instm/NSString/drawAtPoint:withAttributes:

Availability

Available in iOS 7.0 and later.

Thanks Nic.
