“UI更新被应用程序强制禁用”

Question

我正在使用我的一个应用程序Time Out的新版本，它使用登录项助手进行计划。我的一些Alpha测试人员报告了内存泄漏和CPU使用率过高......但我无法重现。

特别是，他们提到性能不佳，以及大量的控制台日志记录，如下所示。什么可能导致这个？

我相信这个错误可能是由于-drawRect：或绘图机器的其他部分太长造成的。这很可能是一个症状，而不是根本问题 - 根本问题是你的绘画超慢。

如果可以，请获取其数据文件。如果不是，请尽可能以最简单的方式进行内置时序的特殊构建。就像，只需在各个点上插入NSLog（），说明它们在哪里，并让用户在应用程序缓慢运行后通过电子邮件向您发送控制台日志。
