I am adding a custom UIButton to the accessoryView of UITableViewCell. I pay strict attention to the retain count and have found that the retain count is incremented to 2 when I add the button but if I put in a release or an autorelease, the code crashes on an invalid reference after loading all the tableViewCells.
First the code and then the console log with the retain counts and the exact crash message.
I test this program with every change for leaks and so this came up as soon as the code was entered, I have no other leaks or crash sources in this code.
Thanks in advance for taking a look!

CGRect buttonFrame;
buttonFrame.origin.x = 0;

buttonFrame.size.width = 25;
buttonFrame.size.height = 25;
btnAdd.frame = buttonFrame;
[btnAdd addTarget:self action:@selector(moveToSchedulingScoring:) forControlEvents:UIControlEventTouchUpInside];
NSLog( @"tour %d", [btnAdd retainCount] );
btnAdd.tag = indexPath.row;
NSLog( @"tour %d tag: %d", [btnAdd retainCount], btnAdd.tag );
cell.accessoryView = btnAdd;
NSLog( @"tour %d %@", [btnAdd retainCount], btnAdd );
[btnAdd release];
