如何让UIAction按钮在越界时弹出

// 创建UIAction按钮
let actionButton = UIAction()

// 设置按钮的frame
actionButton.frame = CGRect(x: 200, y: 200, width: 100, height: 50)

// 获取父视图的边界
let parentViewBounds = parentView.bounds

// 判断按钮的frame是否超出了父视图的边界
if !CGRectContainsRect(parentViewBounds, actionButton.frame) {
    // 调整按钮的位置，使其在边界内显示
    var newFrame = actionButton.frame
    if actionButton.frame.origin.x < parentViewBounds.origin.x {
        newFrame.origin.x = parentViewBounds.origin.x
    }
    if actionButton.frame.origin.y < parentViewBounds.origin.y {
        newFrame.origin.y = parentViewBounds.origin.y
    }
    if actionButton.frame.maxX > parentViewBounds.maxX {
        newFrame.origin.x = parentViewBounds.maxX - actionButton.frame.width
    }
    if actionButton.frame.maxY > parentViewBounds.maxY {
        newFrame.origin.y = parentViewBounds.maxY - actionButton.frame.height
    }
    actionButton.frame = newFrame
}

// 添加按钮到父视图
parentView.addSubview(actionButton)

// 如果需要动画效果，可以使用UIView的动画方法来实现按钮的平滑移动
UIView.animate(withDuration: 0.3) {
    actionButton.frame = newFrame
}
