UIButton deallocated issue

I received this message from the debugger console :

-[UIButton release]: message sent to deallocated instance 0x1836b0

But I don't create UIButton programmatically, all my buttons have created in Interface Builder. Each of them are linked to a function, like this :

-(IBAction)theFunction:(UIButton *)sender;

In lot of this functions, I don't use the variable sender. I don't even try to release it. So I don't understand why my application try to release my buttons. Do I do something 开发者_运维技巧in Interface Builder to release or not my UIButton? Is it about the picture I put in the UIButton? If I use the variable (UIButton *)sender, do I need to release it? This problem stucks me because of it my application crashes.

Edit:

- (IBAction)showPopoverOverview:(UIButton *)sender {
    TouchPlanePopover *content = [[TouchPlanePopover alloc] init];
    [content setTheAlbum:@"Overview"];

    // Setup the popover for use in the detail view.
    detailViewPopover = [[UIPopoverController alloc] initWithContentViewController:content];
    detailViewPopover.popoverContentSize = CGSizeMake(600., 400.);
    detailViewPopover.delegate = self;  // Set the sender to a UIButton.

    // Present the popover from the button that was tapped in the detail view.
    [detailViewPopover presentPopoverFromRect:sender.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];

    // Set the last button tapped to the current button that was tapped.
    lastTappedButton = sender;
    [content release];
}

detailViewPopover is create in .h like this : @property (nonatomic, retain) UIPopoverController *detailViewPopover;

Thans for your help Let me know if you need more information, I will edit the post

-(IBAction)theFunction:(UIButton *)sender

-(IBAction)theFunction:(id)sender
