Objective c 不再使用故事板而不是XIB文件

另一个问题：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:     (NSDictionary *)launchOptions
{
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];

if ([prefs objectForKey:@"PuzzlePicture"] == nil) {
    [prefs setBool:FALSE forKey:@"Refresh"];
    [prefs setInteger:0 forKey:@"PuzzlePicture"];
    [prefs setBool:TRUE forKey:@"CountMoves"];
    //[prefs setBool:TRUE forKey:@"Timer"];
    [prefs setInteger:1 forKey:@"PuzzleLayoutX"];
    [prefs setInteger:1 forKey:@"PuzzleLayoutY"];
}

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
SliderGaloreViewController *sliderGaloreViewController = [[SliderGaloreViewController   alloc] initWithNibName:@"SliderGaloreViewController" bundle:nil];
self.window.rootViewController = sliderGaloreViewController;
[self.window makeKeyAndVisible];
return YES;
}

- (IBAction)showInfo:(id)sender
{
SliderGaloreFlipsideViewController *controller = [[SliderGaloreFlipsideViewController alloc] initWithNibName:@"SliderGaloreFlipsideViewController" bundle:nil];
controller.delegate = self;
controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentViewController:controller animated:YES completion:nil];
}

即使有这样的代码：我仍然得到

“应用程序启动结束时，应用程序窗口应具有根视图控制器”

我决定现在使用一个故事板而不是许多XIB文件，我有两段代码给出了SIGABRT错误。您能看一下它们并指出如何修复错误吗。提前谢谢

更新1: 顺便说一下，错误是：
由于未捕获的异常“NSInternalInconsistencyException”而终止应用程序，原因：“-[UIViewController\u loadViewFromNibNamed:bundle:]加载了“SliderGaloreViewController”nib，但未设置视图出口。”

原因1（在appdelegate中）：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:     (NSDictionary *)launchOptions
{
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];

if ([prefs objectForKey:@"PuzzlePicture"] == nil) {
    [prefs setBool:FALSE forKey:@"Refresh"];
    [prefs setInteger:0 forKey:@"PuzzlePicture"];
    [prefs setBool:TRUE forKey:@"CountMoves"];
    //[prefs setBool:TRUE forKey:@"Timer"];
    [prefs setInteger:1 forKey:@"PuzzleLayoutX"];
    [prefs setInteger:1 forKey:@"PuzzleLayoutY"];
}

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
SliderGaloreViewController *sliderGaloreViewController = [[SliderGaloreViewController   alloc] initWithNibName:@"SliderGaloreViewController" bundle:nil];
self.window.rootViewController = sliderGaloreViewController;
[self.window makeKeyAndVisible];
return YES;
}

- (IBAction)showInfo:(id)sender
{
SliderGaloreFlipsideViewController *controller = [[SliderGaloreFlipsideViewController alloc] initWithNibName:@"SliderGaloreFlipsideViewController" bundle:nil];
controller.delegate = self;
controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentViewController:controller animated:YES completion:nil];
}

原因2（在Viewcontroller.m中）：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:     (NSDictionary *)launchOptions
{
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];

if ([prefs objectForKey:@"PuzzlePicture"] == nil) {
    [prefs setBool:FALSE forKey:@"Refresh"];
    [prefs setInteger:0 forKey:@"PuzzlePicture"];
    [prefs setBool:TRUE forKey:@"CountMoves"];
    //[prefs setBool:TRUE forKey:@"Timer"];
    [prefs setInteger:1 forKey:@"PuzzleLayoutX"];
    [prefs setInteger:1 forKey:@"PuzzleLayoutY"];
}

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
SliderGaloreViewController *sliderGaloreViewController = [[SliderGaloreViewController   alloc] initWithNibName:@"SliderGaloreViewController" bundle:nil];
self.window.rootViewController = sliderGaloreViewController;
[self.window makeKeyAndVisible];
return YES;
}

- (IBAction)showInfo:(id)sender
{
SliderGaloreFlipsideViewController *controller = [[SliderGaloreFlipsideViewController alloc] initWithNibName:@"SliderGaloreFlipsideViewController" bundle:nil];
controller.delegate = self;
controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentViewController:controller animated:YES completion:nil];
}

initWithNibName

不再在故事板中使用，完全忘记NIB

SliderGaloreFlipsideView

是标识符，表示在XCode中设计时提供的

故事板ID

return YES;

如果您试图设置根控制器，则删除所有代码并在情节提要中设置：

等等，不，我想我明白了。然而，App delegate中是什么？@gjys2000查看我的编辑，我不知道您该代码在appdelagate中，

Main

是故事板的名称抱歉，我没有指出它是错误的。然而，错误的第二个原因确实不在故事板中——第一个是。我想知道如何解决问题的第一个原因error@gjys2000查看我的ediyBut现在我有一个错误：警告：尝试显示不在窗口层次结构中的视图！2014-09-14 17:07:12.361 SliderGalore益智游戏[4680:70b]预计在应用程序启动结束时，应用程序窗口将有一个根视图控制器
