从 .dae 创建场景会引发 EXC_BREAKPOINT答案

【问题标题】：Creating scene from .dae throws EXC_BREAKPOINT从 .dae 创建场景会引发 EXC_BREAKPOINT
【发布时间】：2015-01-14 12:13:57
【问题描述】：
使用 Xcode 在您创建游戏应用程序时自动生成的代码，我设法替换了新的可用的 .dae，但是当我使用更复杂的应用程序时，应用程序崩溃并抛出 EXC_BREAKPOINT()，任何想法的原因以及如何解决它？（未打开的文件是 4.1MB 大，其他打开的都是 450KB、750Kb 或类似的文件）。
这是巨大的崩溃日志（没有删除任何内容）：

【问题讨论】：
似乎不是 SceneKit 错误：线程 15 名称：com.apple.coremedia.recorder.worker
好吧，看来不是这样。因为相同的代码确实适用于其他文件。
标签： ios 3d ios8 collada scenekit
【解决方案1】：
==> 操作系统版本：iOS 7.1 (11D167)
我认为 SceneKit 仅从 iOS8 或更高版本开始受支持？
【讨论】：
有道理，但刚刚更新到iOS8并得到同样的错误=/
您使用的 DAE 文件是否有效？当您在导航器中单击模型时，您能在 XCode 中看到模型吗？你能发布示例代码吗？
那么，在您的 viewDidLoad 中，您所做的只是加载场景而不是其他内容？只需用更复杂的模型替换默认模型 - 它就会崩溃？如果您发布您的代码，也许我们可以帮助您解决。
