You shouldn't use tap gesture for UIAccessibility
ot try to add tap gestures to UIAccessibility.您不应该为
UIAccessibility
使用点击手势,也不要尝试将点击手势添加到 UIAccessibility。 UIAccessibility
is meant for the UIElements
where the people can see/hear what is on the screen. UIAccessibility
适用于人们可以看到/听到屏幕上的内容的UIElements
。 You cannot add UIAccessiility for tap gesture functions.您不能为点击手势功能添加 UIAccessiility。 What you can do is to post a accessibility notification to the user saying tap to perform something.
您可以做的是向用户发布可访问性通知,说点击执行某些操作。 Again, you need to use buttons to perform an action in
UIAccessibility
.同样,您需要使用按钮在
UIAccessibility
执行操作。
You can override accessibilityScroll
method:您可以覆盖
accessibilityScroll
方法:
override func accessibilityScroll(_ direction:
UIAccessibilityScrollDirection) -> Bool {
super.accessibilityScroll(direction)
if direction == UIAccessibilityScrollDirection.left {
// do your stuff
}
if direction == UIAccessibilityScrollDirection.right {
// do your stuff
}
return true
}
Add this to your code 将此添加到您的代码
overrride func viewDidLoad()
{
super.viewDiDLoad()
let tap = UITapGestureRecognizer(target: self, action: "performTap")
self.view.addGestureRecognizer(tap)
}
And to perform the necessary action, add your required code here 并执行必要的操作,请在此处添加所需的代码
func performTap()
{
// Perform you action here
}
