添加两个xib文件支持iphone屏幕

Question

请教一个关于iphone屏幕尺寸的问题，

我创建了两个xib文件（MainWindow.xib和MainWindowiPhone5.xib）。这样我的屏幕就可以支持两种屏幕尺寸。

我试过在AppDelegate.m中编程，但是没有实现。

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

if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone){
    UIStoryboard *storyBoard;

    CGSize result = [[UIScreen mainScreen] bounds].size;
    CGFloat scale = [UIScreen mainScreen].scale;
    result = CGSizeMake(result.width * scale, result.height * scale);

    if(result.height == 1136){
        storyBoard = [UIStoryboard storyboardWithName:@"MainWindowiPhone5" bundle:nil];
        UIViewController *tabBarController = [storyBoard instantiateInitialViewController];
        [self.window.rootViewController = self.tabBarController];
    }
}

return YES;
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
// Set the tab bar controller as the window's root view controller and display.
self.window.rootViewController = self.tabBarController;
tabBarController.moreNavigationController.navigationBar.tintColor = [UIColor blackColor];
[self.window makeKeyAndVisible];
return YES;
}

如何让两个xib都能正常运行呢？

应该是这样：

iPhone-4S屏幕:

 if ([[UIScreen mainScreen] bounds].size.height == 480)
 {
   ---- Your Code ----
 }

iPhone-5 屏幕:

 if ([[UIScreen mainScreen] bounds].size.height == 568)
 {
   ---- Your Code ----
 }
