设置UIContextualAction大小

Question

我想知道是否可以设置UIContextualAction的大小(宽度和高度)。

我在UIContextualAction中找不到任何允许我这样做的成员，所以我想知道是否有可以这样做的方法？

action.image = UIGraphicsImageRenderer(size:CGSize(width: 35, height: 35  )).image { _ in
    UIImage(named:"Delete")?.draw(in: CGRect(x:  0, y: 0, width: 35, height: 35))
}

action.backgroundColor = UIColor.red
return action

我找到了这篇文章，背后的想法是使用自定义按钮和使用UIGesture

您可以使用此语法来设置UIContextualAction的宽度和高度

let contextAction = UIContextualAction(style: .normal, title: "", handler: { 
        (param: (Bool) -> Void) in param(true)
})  

contextAction.image = UIGraphicsImageRenderer(size: CGSize(160, 90)).image { 
    _ in UIImage(named: "someObject")!.draw(in: CGRect(40, 10, 200, 100))
}

contextAction.backgroundColor = .green
