swift - 应用程序崩溃并显示 EXC_BAD_ACCESS(代码 = 1，地址 = 0x0)

Question

我知道有很多这样的问题，所以我尝试提供尽可能多的细节。我用 SpriteKit 开发了游戏和几个场景。当我从一个场景转换到另一个场景时，我收到 EXC_BAD_ACCESS(code = 1，address = 0x0)。

使用 bt 我有这个:

(lldb) bt

也许这很重要:在下一个场景中didMoveToView我预加载纹理(几个 map 集)。

更新#1

我启用了地址清理程序，现在它在其中崩溃了:

Answer 1

您添加particleEmitter吗？到第一个场景？您使用 .targetNode的属性(property)particleEmitter ？

如果是这样，我也遇到了同样的问题。 SpriteKit 中似乎存在一个错误，需要您手动设置 .targetNode属性至nil在改变场景之前。试试particleEmitter?.targetNode = nil在 deinit函数或类似...

就我而言，我使用了 targetNode只是为了使发射器的粒子出现在背景顶部，但您可以使用 .zPosition 获得相同的行为和.particleZPosition发射器的属性(我将这两个属性设置为高于背景对象的 .zPosition 的数字)，从而避免使用 targetNode .

希望这对您有帮助。
