How to find memory leaks if they cause the app to crash?

Question

I used Leak Instruments to find Leaks and set NSZombieEnabled to YES . When I press a button or a particular row from tableView my app crashes and I am unable to find any information in Instruments.

I followed the tutorial here:

How can I identify or get more information in Instruments when my app is crashing?

Answer 1

Use Zombie for finding out the Zombie message. It will show you Pink flag with message.

Answer 2

您可以通过从编辑模式启用并在“运行”选项卡中选中“启用僵尸对象”来使用“僵尸”消息，并且可以从控制台查看已释放的对象

Answer 3

Zombies are not the only thing you can have there.

The only way to find leaks is to you profiler with "Leaks" component.

Try also running Project / Analyze for static analyze of your code about memory management errors.

For crash - I think you just have error in code - not really leak. Enable exception breakpoint in your xcode to catch a problem !
