我想在程序的某个点为 iphone 和 ipad 加载不同的 xib，但想重用大部分代码。我怎样才能做到这一点？

【解决方案1】：

将~ipad 或~iphone 附加到文件名的末尾。比如SomeViewController~ipad.xib 或SomeViewController~iphone.xib。

见iOS Supports Device-Specific Resources。

如果您创建一个通用的模板项目，您可以检查为该版本创建的代码。例如：

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

    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

  if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
      MasterViewController *masterViewController = [[MasterViewController alloc] initWithNibName:@"MasterViewController_iPhone" bundle:nil];
      self.navigationController = [[UINavigationController alloc] initWithRootViewController:masterViewController];
      self.window.rootViewController = self.navigationController;
  } else { // iPad
      MasterViewController *masterViewController = [[MasterViewController alloc] initWithNibName:@"MasterViewController_iPad" bundle:nil];
      UINavigationController *masterNavigationController = [[UINavigationController alloc] initWithRootViewController:masterViewController];

      PSGameViewController *detailViewController = [[PSGameViewController alloc] initWithNibName:@"DetailViewController_iPad" bundle:nil];
      UINavigationController *detailNavigationController = [[UINavigationController alloc] initWithRootViewController:detailViewController];

      self.splitViewController = [[UISplitViewController alloc] init];
      self.splitViewController.delegate = detailViewController;
      self.splitViewController.viewControllers = [NSArray arrayWithObjects:masterNavigationController, detailNavigationController, nil];

      self.window.rootViewController = self.splitViewController;
  }

  [self.window makeKeyAndVisible];
  return YES;
}

或来自tableView:didSelectRowAtIndexPath:

if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
  if (self.detailViewController == nil) {
      self.detailViewController = [[PSGameViewController alloc] initWithNibName:@"PSGameViewController_iPhone" bundle:nil];
  }

  self.detailViewController.model = selectedModel;
  [self.navigationController pushViewController:self.detailViewController animated:YES];
  self.pushedIndexPath = indexPath;


} else { // iPad

  self.detailViewController.model = selectedModel;
}
