message sent to deallocated instance error

[chatvenkat]

Hi,

I'm calling segue on click of the other button, and this throws "message sent to deallocated instance" error on line #532 in LMAlertView.m file. The line is shown below.
if ([self.delegate respondsToSelector:@selector(alertView:didDismissWithButtonIndex:)]) {
[self.delegate alertView:(UIAlertView *)self didDismissWithButtonIndex:buttonIndex];
}

This is my code on alertview delegate.
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
if(buttonIndex==1){
[alertView dismissWithClickedButtonIndex:-1 animated:true];
alertView=nil;
[self performSegueWithIdentifier:@"xxxx" sender:self];
}
}

Any suggestions please advice ?
