cocoa绘画中文

绘画中文：

Quartz中CGContextShowTextAtPoint不支持中文，用以下方式绘画

    NSGraphicsContext *gc = [NSGraphicsContextgraphicsContextWithGraphicsPort:context flipped:NO];

        [NSGraphicsContextsetCurrentContext:gc];

        [gcflushGraphics];

        [strtextdrawAtPoint:origin withAttributes:nil];

        [NSGraphicsContextrestoreGraphicsState];

以下是将字符串内容转换为矢量路径图形

- (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);

        

}
