OCSwift工程去除MainStoryBoard

OC/Swift工程去除MainStoryBoard 背景

iOS MainStoryBoard 在实际开发过程中，使用场景并不多，（做做demo除外），但删除它的次数也不多，给CV战士提供一套快捷入口

准备 Xcode工程 OC去除ManStoryBoard

1，删除Main.storyboard文件
2，工程-> TARGETS -> Info.plist中 删除Main storyboard file base name
3，工程AppDelegate.m改造

// 引入主控制器
#import "ViewController.h"
@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    // Override point for customization after application launch.

    ViewController *viewController = [[ViewController alloc] init];
    //如果不需要NavigationController时，直接 self.window.rootViewController = viewController; UITabBarController一样逻辑
    UINavigationController *nVC = [[UINavigationController alloc] initWithRootViewController:viewController];
    self.window.rootViewController = nVC;

    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];
    return YES;
}

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        
        self.window = UIWindow(frame: UIScreen.main.bounds)
        let vc = ViewController()
        let navVC = UINavigationController(rootViewController: vc)
        
        self.window?.rootViewController = navVC
        self.window?.backgroundColor = .white
        self.window?.makeKeyAndVisible()
        
        return true
    }
