Question

我正在使用SceneKit为iOS开发游戏。当我想将天空盒设置为场景时，我收到一个错误：

var path = "skyboxes.scnassets/skybox"
self.scene!.background.contents = [
        UIImage(named: path+"_right.png"),
        UIImage(named: path+"_left.png"),
        UIImage(named: path+"_top.png"),
        UIImage(named: path+"_bottom.png"),
        UIImage(named: path+"_front.png"),
        UIImage(named: path+"_back.png"),
    ]

错误：无法将类型[UIImage？]的值分配给type的值 AnyObject！

我尝试将数组转换为NSArray或AnyObject数组，但这不起作用。

有人可以帮助我吗？

contents的类型为[AnyObject!];所以，以下应该有效：

scene!.background.contents =
[
    UIImage(named: path+"_right.png") as UIImage!              
    UIImage(named: path+"_left.png") as UIImage!,
    UIImage(named: path+"_top.png") as UIImage!,
    UIImage(named: path+"_bottom.png") as UIImage!,
    UIImage(named: path+"_front.png") as UIImage!,
    UIImage(named: path+"_back.png") as UIImage!,
]
