在 xcode 4 错误中将 iphone 应用程序转换为通用应用程序

Question

我正在尝试将 iphone 应用程序转换为通用应用程序，这是我的代码

if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
        self.viewController = [[ViewController alloc] initWithNibName:@"ViewController_iPhone" bundle:nil];

        //  self.viewController = [[SearchViewController alloc] initWithNibName:@"SearchViewController" bundle:nil];
        [self.window addSubview:self.viewController.view];
        [self.timer invalidate];
        self.timer = nil;
        self.timer = [NSTimer scheduledTimerWithTimeInterval: 3 target: self selector: @selector (pullnextview) userInfo: nil repeats: YES];
    } else {
        self.viewController = [[ViewController alloc] initWithNibName:@"ViewController_iPad" bundle:nil];
        [self.window addSubview:self.viewController.view];
        [self.timer invalidate];
        self.timer = nil;
        self.timer = [NSTimer scheduledTimerWithTimeInterval: 3 target: self selector: @selector (Ipadpullnextview) userInfo: nil repeats: YES];
    }

我正在调用包含相同代码但 .xib 不同的两个不同函数。之后，当我去运行代码时，这个错误就来了。

================================================ ====================================

 *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UIViewController _loadViewFromNibNamed:bundle:] loaded the "IpadSearchViewController" nib but the view outlet was not set.'

谁能帮帮我。我是本节的新手。

转到您的 iPad XIB 并通过右键单击视图连接视图插座，然后将视图的引用插座连接到文件所有者..它应该可以正常工作
