如果你希望将某一段文本转化为NSBezierPath路径，然后进行放大或者用特殊方式进行描绘，如何实现呢？下面是方法。

 

- (NSBezierPath *) makePathFromString: (NSString *) string
                              forFont: (NSFont *) font
{
    NSTextView *textview;
    textview = [[NSTextView alloc] init];
        
    [textview setString: string];
    [textview setFont: font];
        
    NSLayoutManager *layoutManager;
    layoutManager = [textview layoutManager];
        
    NSRange range;
    range = [layoutManager glyphRangeForCharacterRange:
                      NSMakeRange (0, [string length])
                                                         actualCharacterRange: NULL];
    NSGlyph *glyphs;
    glyphs = (NSGlyph *) malloc (sizeof(NSGlyph)
                                 * (range.length * 2));
    [layoutManager getGlyphs: glyphs range: range];
        
    NSBezierPath *path;
    path = [NSBezierPath bezierPath];
        
    [path moveToPoint: NSMakePoint (20.0, 20.0)];
    [path appendBezierPathWithGlyphs: glyphs
                                                    count: range.length inFont: font];
        
    free (glyphs);
    [textview release];
        
    return (path);
        
} // makePathFromString
