最近用xcode7.1.1 新建了一个工程，工程里默认有 UISplitViewController 等类的创建。查看Main.storbBoard 发现，里边默认用的就是 SplitViewController 。但是这不是我想要的。我想自己写入口。
之前 是这样
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
UISplitViewController *splitViewController = (UISplitViewController *)self.window.rootViewController;
UINavigationController *navigationController = [splitViewController.viewControllers lastObject];
navigationController.topViewController.navigationItem.leftBarButtonItem = splitViewController.displayModeButtonItem;
splitViewController.delegate = self;
return YES;
}
后来我删除了storyboard，删除了didfinishLaunching 里边的代码（return YES）除外。新建了一个VC。然后xib同时创建。之后在didfinishlaunching里边写：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
_window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
self.window.backgroundColor = [UIColor redColor];
[_window makeKeyAndVisible];
RXScrollViewViewController *mVC = [[RXScrollViewViewController alloc]initWithNibName:@"RXScrollViewViewController" bundle:[NSBundle mainBundle]];
self.window.rootViewController = mVC;
return YES;
}
这样运行，发现会崩溃。
报错为
test[46315:616190] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Could not find a storyboard named 'Main' in bundle NSBundle </Users/red/Library/Developer/CoreSimulator/Devices/26AE60B2-3302-407F-949B-805BF6AB486F/data/Containers/Bundle/Application/41A7AEFA-96CC-4F1A-BFF0-4365E39463EA/test.app> (loaded)'
因为plist里边有个属性，是设置加载main.storyboard的。故需要删除 Main storyboard file base name属性，或者 属性后边string 类型的置为空。运行，搞定。
