为iPhone 5 @ app start加载不同的Storyboard [英] Load different Storyboard for iPhone 5 @ app start
本文介绍了为iPhone 5 @ app start加载不同的Storyboard的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我在 AppDelegate.m 中使用以下代码来检测用户正在使用的设备:
I am using the following code in my AppDelegate.m to detect which device the user is using:
- (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,但是没有故事板即将到来up ...
But when I build the App the NSLog is shown, but no Storyboard is coming up...
- 部署信息中的主要故事板字段为空,以便代码确定要加载的内容......
有人可以帮助我吗?

推荐答案
这是我现在在另一篇文章中找到的方法:
Here is a way I now found on a other post:
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;
}
