Xcode Instruments - Enable NSZombie Detection? Where is it?
提问by DuckDucking
I have watched this video http://www.markj.net/iphone-memory-debug-nszombie/
我看过这个视频 http://www.markj.net/iphone-memory-debug-nszombie/
The guy shows an option called Enable NSZombie Detection on Allocations inside instruments, but my Instruments doesn't shows this option. This guy's video was done using a one year old version of Instruments and I am using Xcode 3.2.5. Do you guys know where this option is now? How can I enable it for iPhone apps?
这家伙显示了一个名为 Enable NSZombie Detection on Allocations inside Instruments 的选项，但我的 Instruments 没有显示此选项。这家伙的视频是使用一年前的 Instruments 版本完成的，我使用的是 Xcode 3.2.5。你们知道现在这个选项在哪里吗？如何为 iPhone 应用程序启用它？
thanks
谢谢

In XCode 4.0, this 'Enable Zombie' option is only present in iPhone simulator and not when you profile on actual device.
在 XCode 4.0 中，此“启用僵尸”选项仅出现在 iPhone 模拟器中，而不会出现在您在实际设备上进行配置时。

The zombie option is available in Xcode 3.2.6 under the allocations tool if you run in the simulator. For debugging memory crashes due to too many dealloc, the simulator will work just as well as the device nearly every time. BTW I am 'The guy' in the question ;-)
如果您在模拟器中运行，则僵尸选项在 Xcode 3.2.6 的分配工具下可用。为了调试由于dealloc过多而导致的内存崩溃，模拟器几乎每次都可以像设备一样工作。顺便说一句，我是问题中的“那个人”；-)

You can find it in Instruments in the Allocations Instrument. The easiest thing to do is to select:
您可以在分配工具中的工具中找到它。最简单的做法是选择：
Run -> Run with Performance Tool -> Allocations
运行 -> 使用性能工具运行 -> 分配
This will start the application and Instruments will start recording. However, the Zombie detection may be off. To turn it on, stop the recording, click on the 'i' icon, and check 'Enable NSZombie detection'. Once it is enabled, start the recording again.
这将启动应用程序，仪器将开始记录。但是，僵尸检测可能已关闭。要打开它，请停止录制，单击“i”图标，然后选中“启用 NSZombie 检测”。启用后，再次开始录制。
It should be noted that in XCode 4.0, one can only enable zombie detect in the simulator, not when running on a device.
需要注意的是，在 XCode 4.0 中，只能在模拟器中启用僵尸检测，而不能在设备上运行时启用。
