Xcode5中如何切换Storyboards为xib

在Xcode5中，当创建一个带View的iPhone项目时，默认必须使用Storyboards，不再支持切换xib的checkbox。本文讲解如何手动切换到使用xib来布局。

1，把Main.storyboard从项目中移除

2，添加xib文件到项目中。添加一个新文件，选择View，命名和\*ViewContorller相同。

3，把Main storyboard对应的项从plist文件中移除

4，在\*AppDelegate中添加类似代码

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

如果ARC关闭的话，以上代码需要手动添加autorelease，这里不详述了。

5，可选：关闭ARC。 在项目的build setting中，找到 Objective-C Automatic Reference Counting, 设置为No

6，把xib关联到对应的ViewController上，否则会报如下错误

**NibName\[2203:207\] \*\*\* Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-\[UIViewController \_loadViewFromNibNamed:bundle:\] loaded the "loc" nib but the view outlet was not set.'**

步骤（参考自 [loaded some nib but the view outlet was not set][]）：

1). 点击我们要加载的 xib 文件

2). 在右边选中 File's Owner

3). 在 File's Owner 的 [![image][image 3]][image_image 3] 选项卡的“Custom Class” 属性设置中，将 Class 的值改成对应的 VC， 这里改成 UIViewController,

4). 这时候，在File's Owner 的 [![image][image 6]][image_image 6]选项卡中， 就 会出现“待连接设置” 的 view 属性， 也即我们的编译器 告诉我们的 **the view outlet was not set** 中的 view。当 File's Owner 的 class 为 NSObject 时候，是没有 view 属性的。

连接 view 属性(把连线拖动到xib设计器中进行连接)，
