Question

Whenever I am trying to update the UIActivityIndicatorView from a thread, the app is getting crashed by throwing an exception

modifying layer that is being finalized – 0x7e177fd0
-[CALayer removeAnimationForKey:]: message sent to deallocated instance 0x7e177fd0

When I try tracking the memory leaks form the mallocDebugger tool, this crash is not happening at all the time happening 1 out of 10

please help me out from this memory issue

Thread implementation:

NSAutoreleasePool *pool = [[NSAutoreleasePool alloc]init];

[autoRechargeCell addSubview:activityIndicator];
[self.activityIndicator startAnimating];
if( [PennyTalkAPI getBalanceInfoForAccount:appDelegate.accountNumber withPIN:appDelegate.pinNumber])
{   
    [autoRechargeCell.switchField setOn:[[NSUserDefaults standardUserDefaults] boolForKey:@"AutoRecharge"]];
    [self.activityIndicator stopAnimating];   <<<<<<<<<<<<<<<<<<<<<< 
}
else
{
    [self.activityIndicator stopAnimating];
}

[pool release]; 

This is the code I have written.

You are updating it from secondary thread that why it is crashing call this on main thread like

   [self.activityIndicator performSelectorOnMainThread:@selector(stopAnimating) withObject:nil waitUntilDone:NO];  

I think it may help you ….
