在为ipad复制xib后，GUI不正确？

Question

我通过复制目标将iphone xib复制到iPad xib中，现在我的大部分xib都被正确转换为iPad大小，但是有些xib仍然仅显示为iphone大小。除了大多数GUI功能，如警报视图显示，行动表都不是根据iPad。我需要做些什么改变才能完美地适用于iPad。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    self.viewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];
    return YES;
}

编辑：GUI问题我在行动表中给出了两个选项YES和NO，只有YES显示NO隐藏在某个地方..

感谢

应用启动时，您没有加载正确的NIB。这是Xcode“Single View”应用程序模板提供的代码，它检测设备并加载相应的NIB文件：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
        self.viewController = [[MainViewController alloc] initWithNibName:@"MainViewController_iPhone" bundle:nil];
    } else {
        self.viewController = [[MainViewController alloc] initWithNibName:@"MainViewController_iPad" bundle:nil];
    }
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];
    return YES;
}

问题不在于转换，它与ipad中的Action表的使用有关。检查如何在ipad中使用操作表，
