Running from memory, but lack of excessive distribution of objects in the Tools

Question

I have an iPad app that crashes due to low memory. However, the tools do not show a significant amount of memory allocated using ObjectAlloc - it remains at the level of 1 MB for the entire life of the application. Leaks show less than 1 kB leaked during the course. The memory monitor shows that free memory on devices drops significantly when used, eventually dropping to such an extent that it is not in memory. Here is a screenshot of the tools:

I am completely at a dead end. As far as I can tell, this basically says that with respect to my application I never use more than 750 KB, but the device still does not have enough physical memory, which leads to a failure / application of my application output.

I am new to debugging memory issues using Xcode. Am I measuring it wrong? Is there any other way to see where this memory goes?

Answer 1

If you look at the Leaks line, you have an entire memory that flows in sequence. Make sure that you free any objects that you have allocated, or that your classes own the links.
