获取辅助功能以识别一个UITextView中的两个超链接的方法如下:
示例代码:
yourTextView.isAccessibilityElement = true
yourTextView.accessibilityTraits = UIAccessibilityTraitLink
示例代码:
class CustomAccessibilityElement: UIAccessibilityElement {
override init(accessibilityContainer container: Any) {
super.init(accessibilityContainer: container)
self.isAccessibilityElement = true
self.accessibilityTraits = UIAccessibilityTraitLink
}
}
// 创建自定义辅助功能元素
let link1 = CustomAccessibilityElement(accessibilityContainer: yourTextView)
link1.accessibilityLabel = "链接1"
link1.accessibilityFrame = yourTextView.convert(link1Frame, to: nil) // 设置链接1的边界框
let link2 = CustomAccessibilityElement(accessibilityContainer: yourTextView)
link2.accessibilityLabel = "链接2"
link2.accessibilityFrame = yourTextView.convert(link2Frame, to: nil) // 设置链接2的边界框
// 将链接添加到UITextView的accessibleElements数组中
yourTextView.accessibleElements = [link1, link2]
class YourViewController: UIViewController, UITextViewDelegate {
// ...
func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange) -> Bool {
// 处理超链接点击事件
if URL.absoluteString == "链接1的URL" {
// 处理链接1的点击事件
return false // 如果不希望打开链接,返回false;否则返回true
} else if URL.absoluteString == "链接2的URL" {
// 处理链接2的点击事件
return false // 如果不希望打开链接,返回false;否则返回true
}
return true
}
}
以上方法将允许辅助功能系统正确地识别UITextView中的两个超链接,并为用户提供适当的反馈和交互。
