我试图增加自定义UIView()中按钮的点击目标,该UIView()是另一个父视图的子视图。我使用convertToScreenCoordinates()尝试实现这一目标。下面是一个例子
let rect2 = CGRect(x: 25, y: 21, width: 200, height: 44)
let newRect = UIAccessibility.convertToScreenCoordinates(rect2, in: self)
其中self是自定义UIView()
调试中,我看到newRect = CGRect(0,0,0,0)
因此
button.accessibilityFrame = newRect // Does not work as intended as VoiceOver frame is now size 0,0 and origin 0,0
答案 0 :(得分:1)
我遇到了同样的问题。原来,我是在放置视图之前设置accessibilityFrame
属性。我通过将代码更改为自定义视图的layoutSubviews
方法来解决此问题。
override func layoutSubviews() {
super.layoutSubviews()
let rect2 = CGRect(x: 25, y: 21, width: 200, height: 44)
let newRect = UIAccessibility.convertToScreenCoordinates(rect2, in: self)
button.accessibilityFrame = newRect
}
