我在AppDelegate.m中使用以下代码来检测用户正在使用的设备：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
if(UI_USER_INTERFACE_IdioM() == UIUserInterfaceIdiomPhone)
{
CGSize result = [[UIScreen mainScreen] bounds].size;
if(result.height == 480)
{
NSLog(@"iPhone 3,5 Inch");
[UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:nil];
}
if(result.height == 568)
{
NSLog(@"iPhone 4 Inch");
[UIStoryboard storyboardWithName:@"iPhone5-storyboard" bundle:nil];
}
}
return YES;
}
但是当我构建应用程序时,会显示NSLog,但是没有Storyboard即将出现…

有些可以帮我吗
Thx和来自德国的最好的问候

解决方法
这是我现在在另一篇文章中发现的一种方式：
if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPhone) { // The iOS device = iPhone or iPod Touch CGSize iOSDeviceScreenSize = [[UIScreen mainScreen] bounds].size; UIViewController *initialViewController = nil; if (iOSDeviceScreenSize.height == 480) { // iPhone 3GS,4,and 4S and iPod Touch 3rd and 4th generation: 3.5 inch screen (diagonally measured) // Instantiate a new storyboard object using the storyboard file named Storyboard_iPhone35 UIStoryboard *iPhone35Storyboard = [UIStoryboard storyboardWithName:@"Storyboard_iPhone35" bundle:nil]; // Instantiate the initial view controller object from the storyboard initialViewController = [iPhone35Storyboard instantiateInitialViewController]; } if (iOSDeviceScreenSize.height == 568) { // iPhone 5 and iPod Touch 5th generation: 4 inch screen (diagonally measured) // Instantiate a new storyboard object using the storyboard file named Storyboard_iPhone4 UIStoryboard *iPhone4Storyboard = [UIStoryboard storyboardWithName:@"Storyboard_iPhone4" bundle:nil]; // Instantiate the initial view controller object from the storyboard initialViewController = [iPhone4Storyboard instantiateInitialViewController]; } // Instantiate a UIWindow object and initialize it with the screen size of the iOS device self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; // Set the initial view controller to be the root view controller of the window object self.window.rootViewController = initialViewController; // Set the window object to be the key window and show it [self.window makeKeyAndVisible]; } else if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad) { // The iOS device = iPad UISplitViewController *splitViewController = (UISplitViewController *)self.window.rootViewController; UINavigationController *navigationController = [splitViewController.viewControllers lastObject]; splitViewController.delegate = (id)navigationController.topViewController; }
