问题描述
我想为我的一些CALayer添加accessibilityLabel。
例如:
I want to add accessibilityLabel for some of my CALayer's. Here is the example:
CALayer *testLayer = [CALayer layer];
[self.view.layer addSublayer:testLayer];
testLayer.backgroundColor = [UIColor purpleColor].CGColor;
testLayer.isAccessibilityElement = YES;
testLayer.accessibilityLabel = @"Some text";
testLayer.frame = CGRectMake(0, 300, 100, 100);
这种方法对我不起作用。
我不想在superview中使用可访问性容器(层次结构复杂)
This approach doesn't work for me. Is it possible to make accessibility working for CALayers?
I don't want to use accessibility container in superview (there is complex hierarchy)
谢谢您!
推荐答案
AFAIK,根据CALayers构建的自定义视图不支持可访问性,所以我想对您的问题的简单回答会不行!您可能要检查苹果公司创建动态元素可访问性的指南。
AFAIK, A custom view built from CALayers does not have support for accessibility so I guess simple answer to your question would be no! You might want to check Apple's guidelines to create Accessibility for Dynamic Elements.
