CATextLayer and attributed strings

  • After rewriting much of my code to transition over to Core Animation,
    I've run across a problem with CATextLayer and displaying attributed
    strings.  The string I am trying to display has a stroke set using
    NSStrokeWidthAttributeName.  Everything seems to work fine, except
    that the text loses it's border whenever it is displayed on the
    CATextLayer.  Why would all the other attributes hold but this one
    gets ignored?  Is there a way around this?

    Here's a code snippet:

    genericPresenterSlideTextAttrs = [NSMutableDictionary
    dictionaryWithObjectsAndKeys:
    [NSFont fontWithName:presentationFontFamily
    size:presentationFontSize], NSFontAttributeName,
    [NSNumber numberWithFloat: -10], NSStrokeWidthAttributeName,
    presenterSlideTextPara, NSParagraphStyleAttributeName,
    [NSColor whiteColor],NSForegroundColorAttributeName,
    nil];

    presentationTextLayer = [[CATextLayer layer] retain];
    presentationTextLayer.string = [[NSAttributedString alloc]
    initWithString: [self presentationText] attributes:
    genericPresenterSlideTextAttrs];
