当我在 UINavigation child 和 child [super dealloc] 中使用后退按钮时，我遇到了应用程序崩溃，称为 application get crash。我试过了，但我找不到任何错误。仪器说下面的问题，但我不明白这里的意思

在这个函数中它说我有问题
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// Navigation logic may go here. Create and push another view controller.
ScenarioDetailViewController* _detailViewController = [[ScenarioDetailViewController alloc] initWithNibName:@"ScenarioDetailViewController" bundle:nil];

[_detailViewController setScenarioId:[self.scenarioId objectAtIndex:indexPath.row]];
[self.navigationController pushViewController:_detailViewController animated:YES];
[_detailViewController release];
}
这条线在函数中有 100% 的责任
[self.navigationController pushViewController:_detailViewController animated:YES];
