sent to deallocated instance

around this issue I had similar issue; turns out I was not retaining a UIButton properly. How I found the cause: - Enable zombies - Run the project with 'Allocations' instrument - Use the app to trigger the bug - Check that Instruments show message 'Zombie Messaged' on the timeline - There should be a link that opens CALayer details: when it was allocated and deallocated - You are interested in the place where is was allocated, should be that aha!!! place in your code
Good luck!

message sent to deallocated instance

will help you yes, your reference counting has errors.
to find the object, enable NSZombies. enabling NSZombies will not free your objects -- but will generate runtime errors when you attempt to message an instance which would (under normal operation) have been deallocated. from there, you can learn more about the object (e.g. its type).

How do I know where this instance is deallocated?

To fix the issue you can do You can set conditional breakpoint when an exception occurs - that way debugger will stop exactly in the place of an error.
To do that go to the breakpoints tab in Navigator section (leftmost xcode section). Click '+' at the bottom to "Add Exception Breakpoint" Add breakpoint (you can choose to catch only objective-c exceptions if you want)

release message sent to deallocated instance, but the instance pointer was not nil

I hope this helps . I'm guessing what's happening here is that at some point in your execution, this method is being called when you have something stored in imageRaw but don't have anything in anImage. In this case, your object in imageRaw will be released but nothing new will be stored to it. This leaves the memory address for the deallocated object in imageRaw but the object no longer exists. Then, the next time you run the method, it checks to see if imageRaw is non-nil (which it is, since it still holds that memory address), tries to call release on that memory, and fails. To avoid this, you can make sure to set imageRaw to nil every time you call release on it:
code :
if (imageRaw)
    [imageRaw release];
    imageRaw = nil;
    .
    .
    .
if (anImage)
    imageRaw = . . .

iOS: why this instance deallocated?

I wish this helpful for you You need to retain the CCSprite. The class method spriteWithFile returns an autoreleased object. The return value stored in spriteInfoBack is not owned by you. That means that the lifetime of the object is until the next autorelease pool is drained. From your code it appears that you are using spriteInfoBack as something that is lazy initialized and then used later. What you will want to do is retain the return value of spriteWithFile like so:
code :
spriteInfoBack = [[CCSprite spriteWithFile:@"bg_player.png"] retain];
