Ios iPhone5屏幕调整

我使用此代码根据设备（iphone 5或更低版本）调整情节提要：

即使我只放置以下位置，代码也不起作用：

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"iphone5 storyboard" bundle:[NSBundle mainBundle]];

…它仍然正常加载iphone

我把它放在：

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

应用程序内代理。是这样吗？？在应用程序设置中，我选择了原始的iphone情节提要，问题在于：

UIScreenOverscanCompensationScale==1136/640

永远不会是真的

检查UIScreenOverscanCompensationScale正在执行的操作并返回BOOL。

是否仍在目标摘要下指定了

MainstryBoard

？我相信这将是应用程序的第一个外观。

我通过以下方式解决了这个问题：

if([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone){
    if([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone && [UIScreen mainScreen].bounds.size.height == 568.0){
        //move to your iphone5 storyboard
        UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"iphone5 storyboard" bundle:[NSBundle mainBundle]];
        UIViewController *vc =[storyboard instantiateInitialViewController];

        // Set root view controller and make windows visible
        self.window.rootViewController = vc;
        [self.window makeKeyAndVisible];
    }
    else{
        //move to your iphone4s storyboard
        UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:[NSBundle mainBundle]];
        UIViewController *vc =[storyboard instantiateInitialViewController];

        // Set root view controller and make windows visible
        self.window.rootViewController = vc;
        [self.window makeKeyAndVisible];
    }}

在Targets Summary页面上，故事板可能设置为MainstryBoard_iPhonewell，我已经决定在Summary=>main storyboard下创建一个故事板。因为我必须决定一个故事板。

if([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone){
    if([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone && [UIScreen mainScreen].bounds.size.height == 568.0){
        //move to your iphone5 storyboard
        UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"iphone5 storyboard" bundle:[NSBundle mainBundle]];
        UIViewController *vc =[storyboard instantiateInitialViewController];

        // Set root view controller and make windows visible
        self.window.rootViewController = vc;
        [self.window makeKeyAndVisible];
    }
    else{
        //move to your iphone4s storyboard
        UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:[NSBundle mainBundle]];
        UIViewController *vc =[storyboard instantiateInitialViewController];

        // Set root view controller and make windows visible
        self.window.rootViewController = vc;
        [self.window makeKeyAndVisible];
    }}
