EXC_BAD_INSTRUCTION 错误,请大家帮忙!

- (void)viewDidLoad {
BlueViewController *blueController = [[BlueViewController alloc]
initWithNibName:@"BlueView" bundle:nil];
self.blueViewController = blueController;
[self.view insertSubview:blueController atIndex:0];
[blueController release];
} 我跟踪,到[self.view insertSubview:blueController atIndex:0];这句的时候就出 EXC_BAD_INSTRUCTION 这个异常了,我是买的IPhone 开发基础教程 里的多视图切换中的例子,我按书上的做了,怎么还会出问题
