PushViewController 不工作
我想创建一个基本的推送视图场景。我有以下代码，但它不起作用。什么也没发生。有人能告诉我为什么吗？
testController *screen2 = [[testController alloc] initWithNibName:nil bundle:nil];
[self.navigationController pushViewController:screen2 animated:YES];
[screen2 release];
i want to create a basic push view scenario. I have the following code but it does not work. Nothing happens. Could someone tell me why?
testController *screen2 = [[testController alloc] initWithNibName:nil bundle:nil];
[self.navigationController pushViewController:screen2 animated:YES];
[screen2 release];

您应该尝试执行 NSLog 来查看 screen2 是否为零。有可能由于某种原因，它没有从相应的笔尖正确加载。顺便说一句，我强烈建议遵守类名大写的惯例。说到这里，你可能会调用 nib 文件 TestController.nib 吗？ （这会导致问题。）
You should try to do an NSLog to see if screen2 is nil. Chances are it is not being appropriately loaded from a corresponding nib for some reason. As an aside, I'd highly recommend sticking to the convention of capitalizing class names. Speaking of which, did you maybe call the nib file TestController.nib? (That would cause the problem.)
