如何为iPad加载不同的nib

Question

当我的应用程序在iPad上运行时，我想为我的根视图加载不同的。xib。正如你从下面的代码中看到的那样，我尝试过这样做，但是发生的事情是线程进入了正确的if语句，所以它识别出它是一个iPad，但是当视图加载时，它加载了iPhone版本的视图。

这是我的代码，我试图在应用程序委托中决定为rootView加载哪个nib:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    //Add status bar
    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
    [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationFade];

    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
        self.window.rootViewController = [[RootViewController alloc] initWithNibName:@"RootViewControlleriPad" bundle:nil];
    } else {
        self.window.rootViewController = [[RootViewController alloc] initWithNibName:@"RootViewController" bundle:nil];
    }

    self.window.rootViewController = self.navigationController; //Adds RootViewController to the NavigationController interface
    self.navigationController.navigationBar.titleTextAttributes =  @{NSForegroundColorAttributeName : [UIColor whiteColor]}; // navigation titles
    self.navigationController.navigationBar.tintColor = [UIColor whiteColor]; // navigation buttons

您需要重做这一行:

self.window.rootViewController = self.navigationController; //Adds RootViewController to the NavigationController interface
