来自string的CGPathRef

请问怎样才能得到法文信件的特定阿拉伯语？ 我刚刚发现CTFontCreatePathForGlyph会给CGPathRef这样的，但它将是文本的轮廓。

我需要这个真正的文本path来显示文本绘图animation..

请任何帮助

你根本不需要把你的path转换成NSString。

您可以创build文本的path，如下所示：

CTFontRef font = CTFontCreateWithName(CFSTR("Helvetica-Bold"), 72.0f, NULL); NSDictionary *attrs = [NSDictionary dictionaryWithObjectsAndKeys: (id)font, kCTFontAttributeName, nil]; NSAttributedString *attrString = [[NSAttributedString alloc] initWithString:@"Hello World!" attributes:attrs]; CTLineRef line = CTLineCreateWithAttributedString((CFAttributedStringRef)attrString); CFArrayRef runArray = CTLineGetGlyphRuns(line); // for each RUN for (CFIndex runIndex = 0; runIndex < CFArrayGetCount(runArray); runIndex++) { // Get FONT for this run CTRunRef run = (CTRunRef)CFArrayGetValueAtIndex(runArray, runIndex); CTFontRef runFont = CFDictionaryGetValue(CTRunGetAttributes(run), kCTFontAttributeName); // for each GLYPH in run for (CFIndex runGlyphIndex = 0; runGlyphIndex < CTRunGetGlyphCount(run); runGlyphIndex++) { // get Glyph & Glyph-data CFRange thisGlyphRange = CFRangeMake(runGlyphIndex, 1); CGGlyph glyph; CGPoint position; CTRunGetGlyphs(run, thisGlyphRange, &glyph); CTRunGetPositions(run, thisGlyphRange, &position); // Get PATH of outline { CGPathRef letter = CTFontCreatePathForGlyph(runFont, glyph, NULL); CGAffineTransform t = CGAffineTransformMakeTranslation(position.x, position.y); CGPathAddPath(letters, &t, letter); CGPathRelease(letter); } } } CFRelease(line); 

这是你如何创build一个path，示例代码请参考这个链接 。 此代码是此示例项目的一部分。 希望这可以帮助你
