NSAutoreleaseNoPool(): Object 0x66ad9d0 of class NSConcreteMutableData autoreleased with no pool in place - just leaking

Question

I am trying to perform thread operation in my project. The things are getting worked but I am getting NSAutoreleaseNoPool(): Object 0x66ad9d0 of class NSConcreteMutableData autoreleased with no pool in place - just leaking pring on my NSLOG.

My Code is..

NSAutoreleasePool *MyPool = [[NSAutoreleasePool alloc] init];
[NSThread detachNewThreadSelector:@selector(insertSyncRec:) toTarget:self withObject:dict];
[MyPool drain]; // [MyPool release]; too

My log message is:

and so on..

What I am missing.. After lot of googling I only found to create a new pool.. but not worked..

Thanks in advance..

Answer 1

Shouldn't the pool be created within the thread itself?

Answer 2

I also had the same problem,instead of attaching the task to a new thread try in the same thread. [self insertSyncRec:dict];

I fixed my problem doing it this
