新建TestController界面，然后在别的界面中添加下面代码，跳转到TestController界面，
代码如下:

//打开新窗口，关闭当前窗口
    TestController *testController = [[TestController alloc] initWithNibName:@"TestController"bundle:nil];
    [self.view.superview addSubview:testController.view];
    [self.view removeFromSuperview];    //removeFromSuperview释放窗口，不用再写release，会自动管理的
    [testController release];
