How to Add a New StoryBoard, and set it to become the Main StoryBoard xCode without error
提问by Confused_person
Currently, I have a working app with a single storyBoard. The working app is based on master-detail view layout. I decided to add a new storyboard, and set it to become the main storyboard. When I click run, it will run and display a blank page, which is what I expected as I have not added any view controllers.
目前，我有一个带有单个故事板的工作应用程序。工作应用程序基于主从视图布局。我决定添加一个新的故事板，并将其设置为主故事板。当我点击运行时，它会运行并显示一个空白页面，这是我所期望的，因为我没有添加任何视图控制器。
I am still new to objective-C, as such, there are many things that I still do not understand, Here comes the interesting part.
我还是Objective-C的新手，因此，还有很多我仍然不明白的地方，有趣的部分来了。
When I add a UIViewController(and associated it to a subclass of UIViewController) inside my newly changed Main storyboard, and then tried to run it, it displays an error.
当我在新更改的主故事板中添加 UIViewController（并将其关联到 UIViewController 的子类），然后尝试运行它时，它显示错误。
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIViewController viewControllers]: unrecognized selector sent to instance 0x7569a80'
Under my AppDelegate:
在我的 AppDelegate 下：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch.
UISplitViewController *splitViewController = (UISplitViewController *)self.window.rootViewController;
UINavigationController *navigationController = [splitViewController.viewControllers lastObject];
splitViewController.delegate = (id)navigationController.topViewController;
return YES;
}
I am not so sure what do I need to add to the code above. I did try the below line without success too,
我不太确定我需要在上面的代码中添加什么。我也尝试过下面的代码但没有成功，
UIViewController *viewController = (UIViewController *)self.window.rootViewController;
As such, how do I solve this problem?
因此，我该如何解决这个问题？

Take storyboard file from New file-->ios-->user interface---> storyboard
从中获取故事板文件 New file-->ios-->user interface---> storyboard
create @propertystoryboard in appdelegate
like
@property在 appdelegate 中创建故事板，例如
@property (nonatomic, retain) UIStoryboard* storyboard ;
before implementation in .m file write:
在 .m 文件中实现之前写：
@interface AppDelegate ()
@property (strong, nonatomic) UIViewController *initialViewController;
@end
This is to take refrence of initial viewcontroller.
这是为了参考初始视图控制器。
then @synthesize storyboardin appdelegate.m
and then for navigation you can write in didFinishLaunchingWithOptions
然后@synthesize storyboard在 appdelegate.m 然后导航你可以写didFinishLaunchingWithOptions
//init storyboard
storyboard = nil;
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"6.0"))
{
CGSize result = [[UIScreen mainScreen] bounds].size;
if(result.height == 480)
{
storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhoneIOS5" bundle:nil];
NSLog(@"Version < 6");
// iPhone Classic
}
if(result.height == 568)
{
// iPhone 5
storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:nil];
NSLog(@"Version 6");
}
//NSLog(@"IOS 6");
}
else
{
storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhoneIOS5" bundle:nil];
//NSLog(@"IOS 5");
}
self.initialViewController = [storyboard instantiateInitialViewController];
//instantiateInitialViewControllermeans it returns the arrow pointed view-controlleron storyboard that is root view controller.
//instantiateInitialViewController意味着它返回故事板上箭头指向的视图控制器，即根视图控制器。
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.rootViewController = self.initialViewController;
[self.window makeKeyAndVisible];

On Xcode 7 you can go to info.plist and set the key "Main storyboard file base name" to the name of your new Storyboard .
在 Xcode 7 上，您可以转到 info.plist 并将键“Main storyboard file base name”设置为新 Storyboard 的名称。
Example: You create a new storyboard file by going to file -> new -> file -> Storyboard file and you save it as "MyAwesomeUI.storyboard" then in info.plist you change the key of "Main storyboard file base name" to "MyAwesomeUI" .
示例：您通过转到文件 -> 新建 -> 文件 -> 故事板文件创建一个新的故事板文件，并将其另存为“MyAwesomeUI.storyboard”，然后在 info.plist 中将“主故事板文件基本名称”的键更改为“MyAwesomeUI”。
Cheers!
干杯!
