3rd level nav controller crashes when trying to connect any outlet

I have a table view nav controller that once a cell is selected it loads to a details view and then another button that leads to a sub details view. Whenev开发者_Python百科er i try add anything to the third level nav view it crashes, be it a label, image, anything, even just image.hidden=YES; crashes? any ideas why?

try this

ThirdController *thirdController = [[ThirdController alloc] initWithNibName:@"ThirdController" bundle:nil];
[self.navigationController pushViewController:thirdController animated:YES];
[thirdController release];
