我正在创建一个多故事板应用。根据要求,我在不同的情况下使用不同的故事板。为了支持所有设备,我必须编写这样的代码:
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"blah_iPhone" bundle:nil];
self.window.rootViewController = [storyboard instantiateInitialViewController];
}
else
{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"blah_iPad" bundle:nil];
self.window.rootViewController = [storyboard instantiateInitialViewController];
}
[self.window makeKeyAndVisible];
我也试过使用代字号(〜),命名故事板如blah~iphone
& blah~ipad
但它会抛出这样的错误:

任何想法??
答案 0 :(得分:0)
也许我错过了一些东西但是我不明白为什么你在使用storyboard文件时手动管理窗口。
我认为您正在为现有项目添加普遍支持。因为如果您创建一个新的通用应用程序,一切都将按照您的需要进行。
您需要在app app delegate中使用application:didFinishLaunchingWithOptions:
方法,如下所示:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch.
return YES;
}
您的目标设置应如下所示,请注意iPhone / iPad开关并为每个设备选择不同的故事板。
