Question

我知道有很多这样的问题，所以我尽量提供尽可能多的细节。我有用SpriteKit和几个场景开发的游戏。当我从一个场景转换到另一个场景时，我得到EXC_BAD_ACCESS (code = 1, address = 0x0)。

bt我有这个：

也许这很重要：在下一个场景didMoveToView中我预加载纹理（几个地图集）。

我启用了地址清理程序，现在它在内部崩溃了：

Answer 1

您是否在第一个场景中添加了particleEmitter？您是否使用.targetNode的{{1}}属性？

如果是这样，我有同样的问题。 SpriteKit中似乎存在一个错误，需要您在更改场景之前手动将particleEmitter属性设置为.targetNode。在nil函数或类似函数中尝试particleEmitter?.targetNode = nil ...

在我的情况下，我使用deinit只是为了使发射器的粒子出现在背景的顶部，但您可以使用targetNode和.zPosition属性获得相同的行为发射器（我将两个属性都设置为高于背景对象.particleZPosition的数字），从而避免使用.zPosition。

我希望这会对你有所帮助。

应用程序崩溃与EXC_BAD_ACCESS（代码= 1，地址= 0x0）
