我有一个问题，我已经编写了我的第一个应用程序，即将完成。
有一个 VC（启动）带有一个按钮，可以将用户带到另一个 VC 中的游戏。
用户可以通过单击第二个 VC 中的按钮返回到第一个（菜单）VC。
在测试过程中，我注意到当点击主页按钮，然后应用程序被买回视图并点击播放按钮时，应用程序崩溃并且设备重新启动。
为了尝试找出原因，我从游戏 VC 中删除了 iAD 和 Games Center。出现同样的问题，但现在只有在重复主页按钮/回到焦点/播放大约 2-3 次之后。
下面是设备控制台，但我是新手，所以我不清楚。
当它崩溃时，它会在崩溃前显示第二个 VB 毫秒或部分显示。
从它可以在线阅读的内容来看，某些内容正在使用大量内存，但我在代码中看不到任何内容（viewdidload 等）。
我运行了分析，只检测到了死存储。
我不能在模拟器上模拟同样的问题，它只发生在设计（iPhone 3）上。我怀疑是因为 Mac 有更多的内存。
当我使用分析仪器时，它不会显示任何内存峰值。
如果您需要任何其他信息，请告诉我。到目前为止，我已经“解决”了很多问题，我迫不及待地想把它带进商店！！
