I'm trying to simulate a medium size city's traffic and keep surpassing the memory capacity of 512M. Is there anyway to increase the memory? Thank you!!
You can increase the maximum memory by going to your simulation properties as shown below:

When a GameScene has been presented, there are two categories which constantly increase in number of persistent#: '_NSArrayM' and 'CAMetalDrawable'. Which results in memory consumption to increase at roughly 0.1 MB every 20 seconds. However, when I set SKView.isPaused = true, memory consumption stops increasing. Is this normal or even bad?
Additionally, how can I clear the persistent data?
If you're still looking for a solution, I had a similar issue.
If you edit scheme and disable Metal API Validation and GPU frame capture, it seemed to fix it for me.
What ranges could be considered Low, Medium, and High in memory usage?
As my app becomes more complex, I notice this number getting higher. I've been trying to use this number as an indicator to how efficiently I'm coding but I've realized I have no bar to compare it with.
How to understand Memory Usage says 1024 Mb to an iPhone/iPad, but obviously all of this memory can't go to the app.
You could get(a pretty nice) overview from this SO question. It won't show you low-medium values, but if you know the limit you can adjust below limit.
If you are near the limits in some view - override didReceiveMemoryWarning and dispose resources accordingly.
My advise is to test always on device, as simulator need a lot memory just because of it's architecture and it's not relative to real devices.
i'm trying to add MKTileOverlay on map. when i start loading tile by fetching it from server, CPU usage suddenly increases. again on doing some action like zoom in zoom out or scrolling map cpu usage increases upto 200% whats the reason.?
You might be allocating some objects continuously.
You can use instrument to check allocations in your app.
Here is my question.
I tried to check my allocation part using Instruments in xcode.
I am doing some image crop Application using CGImageSourceCreateThumbnailAtIndex for processing the images. while doing the process it is taking to much memory and i released it in right manner.
In Instruments the live bytes is 1.56Mb , #living = 22,862 and Overall bytes reaches 1.11Gb after that also it will increase.
This application is not working in ipad1. i dont have ipad2 or 3 in hand to test the application.
In the image some peak points are there. At that point Live Bytes reaches 73MB. and it will be released. will ipad 2 handle this peak ??
Can anyone tell this will cause any memory Problem in device.
How about the overall bytes. is there any limit for this?
yes since overall bytes is just the number of bytes that were EVER allocated.
The longer the app runs, the higher the no.
When I use pagestack to move between pages, the memory of device increases.
Please see memory increase when use PageStack to see more clearly my problem
