Question

我有一个自定义视图。我捕获了视图的屏幕快照，并在NSTextAttachment中将图像用作：

UIImage *image = view.image;
    NSTextAttachment *attachment = [NSTextAttachment new];
    attachment.image = image;

然后我使用以下附件创建一个可变的属性字符串：

NSAttributedString *attrStr = [NSAttributedString attributedStringWithAttachment:attachment];

此代码针对所有视图循环播放，并通过将所有attrStr附加为以下内容来创建一个最终的属性字符串：

[mutableString beginEditing];
    [mutableString appendAttributedString:attrStr];
    [mutableString endEditing];

然后将其设置为UILabel属性文本。

问题：我想让语音遍历属性文本中的各个图像。这样每个图像都可以通过语音清晰对焦。

谢谢!!

遍历单个图像（例如像集合视图）的最佳方法依赖于以下事实：将每个元素定义为特征属性为{{的包装器中的**Queued project collection creation for host: 57cd339d-cdef-48e5-b049-b80de4949dd2 [Info @13:00:26.567] Waiting for servicing.

要了解应如何实施，建议您看一下UIAccessibilityElement视频，其视频内容得到了here的完美总结，展示的示例可以为downloaded。

使用adjustable protocol也可能是一条有趣的调查轨迹。

最后，我认为您不能照原样在属性文本中迭代图像，但是创建一种VoiceOver完全可以理解的可访问结构，如之前定义的那样，可以实现您的目标。< / p>

辅助功能：使带有属性文本的UILabel作为辅助功能容器
