Question

我用ARC创建了一个tabBar应用程序。因此默认设置将自动提供2个viewControllers;

1）FirstViewController.h，FirstViewController.m; FirstViewController_iPhone.xib，FirstViewController_iPad.xib

2）SecondViewController.h，SecondViewController.m，SecondViewController_iPhone.xib，SecondViewController_iPad.xib

我想创建一个新的视图控制器'ViewController3'，但在文件创建过程中，我只能选择创建iPad或iPhone（复选框'Targeted for iPad'）。我需要iPhone和iPad xib，就像为我创建的FirstViewController和SecondViewControllers一样。所以我决定手动创建xib并继续创建没有xibs的文件。

之后我自然而然地手动创建了2个新闻xib; ThirdViewController_iPhone.xib和ThirdViewController_iPad.xib

我将此行添加到原始的AppDelegeate文件中：

UIViewController *viewController1, *viewController2, *viewController3;
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
    viewController1 = [[FirstViewController alloc] initWithNibName:@"FirstViewController_iPhone" bundle:nil];
    viewController2 = [[SecondViewController alloc] initWithNibName:@"SecondViewController_iPhone" bundle:nil];
    viewController3 = [[ThirdViewController alloc] initWithNibName:@"ThirdViewController_iPhone" bundle:nil]; 
} else {
    viewController1 = [[FirstViewController alloc] initWithNibName:@"FirstViewController_iPad" bundle:nil];
    viewController2 = [[SecondViewController alloc] initWithNibName:@"SecondViewController_iPad" bundle:nil];
    viewController3 = [[ThirdViewController alloc] initWithNibName:@"ThirdViewController_iPad" bundle:nil];
}
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2, viewController3, nil];

然后我运行该项目得到了：由于未捕获的异常'NSInternalInconsistencyException'终止应用程序，原因：' - [UIViewController _loadViewFromNibNamed：bundle：]加载了“ThirdViewController_iPhone”笔尖，但未设置视图插件。'

如何设置插座？

对于您的ThirdViewController_iPhone.xib，请按照here指示操作。我认为你需要这样做：

你应该看到“outlet”下面有“view”。将其旁边的圆圈拖到左栏上的“视图”图标
