在Xcode 4中将iPhone应用程序转换为Universal [英] Converting an iPhone app to Universal in Xcode 4

问题描述

我可以在这里使用一点清晰度。
我已经开了一个项目，这是一个完整的iPhone应用程序。然后选择目标，从摘要/设备下拉列表中选择通用，然后按提示制作通用应用程序。
Xcode创建了一个文件夹iPad，其中包含MainWindow-iPad.xib文件。
罚款。

I could use a little clarity here. I've opened a project that is a completed iPhone app. Then selected the target, selected "Universal" from the Summary/Devices dropdown, and followed the prompt to "Make a Universal App." Xcode created a folder "iPad" with the file "MainWindow-iPad.xib" within. Fine.

现在我复制了所有其他nib文件，并在其名称后添加了-iPad。即MySpecialVC.xib被欺骗并重命名为MySpecialVC-iPad.xib。想到的是，Xcode知道一些关于为设备找到正确xib的zoodoo。
不太好。

Now I duplicated all of my other nib files, and added "-iPad" after their name. I.e. "MySpecialVC.xib" was duped and renamed "MySpecialVC-iPad.xib." The thought was that Xcode knows some zoodoo about finding the correct xib for the device. Not so fine.

然后我读到-iPad必须是~ipad（代字号，然后是小写的ipad）。这解决了一些xib的问题，但不是全部。

Then I read that the "-iPad" had to be "~ipad" (tilde, then lower-case ipad). This solved the problem with some of the xibs, but not all of them.

如果我无法解决这个问题。有没有正确的方法呢？

Dang if I can't figure this out. Is there a RIGHT way to do this?

推荐答案

当我创建一个新的通用项目时，我明白了：

When I create a new universal project, I get this:

- (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 = [[ViewController alloc] initWithNibName:@"ViewController_iPhone" bundle:nil];
    } else {
        self.viewController = [[ViewController alloc] initWithNibName:@"ViewController_iPad" bundle:nil];
    }
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];
    return YES;
}

因此很明显代码明确选择了一个xib文件。这不是你的项目的情况吗？

So it's clear the code is explicitly choosing a xib file. Is this not the case for your project?
