xcode 工具导致应用程序崩溃 [英] xcode instruments causing app crash

问题描述

我正在使用 xcode Instruments 来跟踪分配和泄漏.我的应用程序崩溃了.仅在 Instruments 下运行常规调试或发布版本时，它不会崩溃:

非常感谢收到任何想法......

解决方案

作为对 Ian 上述内容的补充:将环境变量NSZombieEnabled"设置为 YES并且希望您获得更多信息的失败.

(在 XCode 4 中，环境变量位于Edit Scheme"下并选择Debug")

I am using xcode Instruments to track Allocations and Leaks. My app is crashing though. It does not crash when running the regular debug or release builds standalone, only when under Instruments:

Any thoughts ideas very gratefully received....

解决方案

As a complement to what Ian says above: set the Environment variable "NSZombieEnabled" to YES and you will hopefully have a more informative fail.

(In XCode 4 the Environment Variables is found under "Edit Scheme" and select "Debug")
