我找到了许多关于如何通过情节提要配置SWRevealViewController 的教程，但我希望完全摆脱情节提要和 xib。

所以我想知道，有没有办法以编程方式配置库？

【解决方案1】：

Swift 5.x 更新（以编程方式）

来自 AppDelegate，在 didFinishLaunchingWithOptions 中：

    let revealController = SWRevealViewController()
    var mainRevealController = SWRevealViewController()

    let sidebar = SideBarViewController()
    let homepage = ViewController()

    let frontNavigationController = UINavigationController(rootViewController: homepage)
    let rearNavigationController = UINavigationController(rootViewController: sidebar)

    revealController.frontViewController = frontNavigationController
    revealController.rearViewController = rearNavigationController
    revealController.delegate = self

    mainRevealController  = revealController

    window = UIWindow(frame: UIScreen.main.bounds)
    window?.makeKeyAndVisible()
    window?.rootViewController = mainRevealController

    return true

斯威夫特 3

    let frontNavigationController:UINavigationController
    let rearNavigationController:UINavigationController
    let revealController = SWRevealViewController()
    var mainRevealController = SWRevealViewController()

    let sidebar = self.storyboard?.instantiateViewController(withIdentifier:  "sidebarMenuVCID")as! sidebarMenu

    let homepage = self.storyboard?.instantiateViewController(withIdentifier: "HomePageVCID") as! HomePage

    frontNavigationController =  UINavigationController(rootViewController: homepage)
    rearNavigationController = UINavigationController(rootViewController: sidebar)

    revealController.frontViewController = frontNavigationController
    revealController.rearViewController = rearNavigationController
    revealController.delegate = self
    mainRevealController  = revealController

    self.window?.rootViewController = mainRevealController

我不知道 Swift 3 中返回的分号！嘘！我从不喜欢那些
完成了请检查

【解决方案3】：

您下载的 SWReveal 包中有示例项目。如果我没记错的话，它们都是以编程方式实现的。

来自示例项目 #2 的 AppDelegate.m：

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

    FrontViewController *frontViewController = [[FrontViewController alloc] init];
    RearViewController *rearViewController = [[RearViewController alloc] init];

    UINavigationController *frontNavigationController = [[UINavigationController alloc] initWithRootViewController:frontViewController];
    UINavigationController *rearNavigationController = [[UINavigationController alloc] initWithRootViewController:rearViewController];

    SWRevealViewController *mainRevealController = [[SWRevealViewController alloc]
        initWithRearViewController:rearNavigationController frontViewController:frontNavigationController];

    mainRevealController.delegate = self;

    self.viewController = mainRevealController;

    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];
    return YES;
}
