Amount of memory used by each thread

Question

I am developing an app that is crashing due to an excess of memory usage. I would like to know the amount of memory that is being used by each active thread so that I can decide which allocated or drawn in screen elements release or remove from view. Is there a way to obtain it?

I have tried using mach.h library but with mach_task_self() I can only access the memory used by the whole application.

Thanks in advance

Answer 1

I think what you want is logMemUsage() .

You can check the Answer from this Question : Watching memory usage in iOS

I think you can get something from this Documentation also : Understanding and Analyzing iOS Application Crash Reports

If you want to check Memory Usage While Application is Running then use Instruments . :

Using Instruments you can check how much memory your app is using. In Xcode4 , use ' Profile ' build, choose Leaks , then click the Library button in the toolbar and add the Memory Monitor instrument .

If you really don't want to use Instruments then you can use Custom Class UIDeviceAdditions : Get current Memory usage

Hope it's Enough.

Answer 2

You can't because threads share the heap. Threads are created with a 512KB stack space , with memory pages allocated as needed. Other than that, there is no memory per thread value stored anywhere.
