第一代和第二代 iPod Touch 上的应用程序崩溃

Question

据报道，我发布的应用程序（Hidden London - Free App）在第二代和第三代 iPod touch 上崩溃。它可以在 iPhone 和 iPad 上正常运行。

谁能帮我解决为什么 iPod Touch 上会发生这种情况？

Answer 1

提示您的应用程序崩溃的原因是 Received memory warning. Level=1。你没记忆了。这可能是您的应用程序用于数据结构的 RAM 量，但当您用完图形内存（即用于合成视图、缓存图像等的内存）时，我更经常看到这种类型的错误。总量第 1 代和第 2 代 iPod touch 上的 RAM 只有 128MB。第 3 代和第 4 代将其提升到 256MB。

日志中的内存相关信息以jetsam: kernel memory event (90), free: 323, active: 1250, inactive: 1494, purgeable: 0, wired: 7841 开头，这是一条“内存不足”警告消息。然后，您会看到一大堆应用程序被操作系统终止（Exited: Killed 和 exited abnormally with signal 9: Killed）。这是 iOS 在低内存条件下的记录行为 - 它会杀死应用程序，直到它有足够的可用内存。

Answer 2

我认为您的应用程序正在使用大量内存，因此它被操作系统杀死了。
