在 Xcode 中显示第一个故事板场景的独特问题 [英] Unique Issue displaying first storyboard scene in Xcode

问题描述

我已经尝试了 2 天来让我的故事板显示此代码:

I have tried for 2 days now to get my storyboard to display with this code:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
   UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
    UIViewController *LoginViewController = [storyboard instantiateInitialViewController];

    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.window.rootViewController = LoginViewController;
    [self.window makeKeyAndVisible];

    return YES;
}

但是，我一直收到这个错误和一个 sigbart 在我的主要:'NSInvalidArgumentException'，原因:'在捆绑 NSBundle(加载)中找不到名为'MainStoryboard'的故事板'

However, I keep getting this error and a sigbart in my main: 'NSInvalidArgumentException', reason: 'Could not find a storyboard named 'MainStoryboard' in bundle NSBundle (loaded)'

Google 中似乎没有出现关于这些错误的任何信息?有没有人知道如何解决它?

Nothing seems to appear in google about these errors? Does anyone have any idea how to fix it?

更新:当我将其更改为:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:nil];
    UIViewController *LoginViewController = [storyboard instantiateInitialViewController];

    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.window.rootViewController = LoginViewController;
    [self.window makeKeyAndVisible];

    return YES;
}

它给了我错误:[3208:c07] 如果应用程序委托要使用主故事板文件，它必须实现 window 属性.

it gives me the errors: [3208:c07] The app delegate must implement the window property if it wants to use a main storyboard file.

{AppDelegate setWindow:]:无法识别的选择器发送到实例 0x962bf30

{AppDelegate setWindow:]: unrecognized selector sent to instance 0x962bf30

[3208:c07] * 由于未捕获的异常NSInvalidArgumentException"而终止应用程序，原因:-[AppDelegate setWindow:]:发送到实例 0x962bf30 的无法识别的选择器"

[3208:c07] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[AppDelegate setWindow:]: unrecognized selector sent to instance 0x962bf30'

推荐答案

终于找到了！！！！！！原来是我忘了把这行代码放在app委托头文件中:

Finally Found It!!!!!! Turns out that I forgot to put this line of code in the app delegate header file:

@property (strong, nonatomic) UIWindow *window;
