如何在无Storyboard的Objective-C项目中集成SideMenu？

Absolutely, you can use the SideMenu library without Storyboards in Objective-C—no problem at all! Let me break down exactly how to set this up, including fixing that initialization issue you're running into.

Step 1: Configure Global SideMenu Settings #

First, set up the base configuration for your side menu in your app delegate's didFinishLaunchingWithOptions method. This defines core behavior and appearance:

#import <SideMenu/SideMenu.h>

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Initialize menu managers to nil first
    SideMenuManager.defaultManager.leftMenuNavigationController = nil;
    SideMenuManager.defaultManager.rightMenuNavigationController = nil;
    
    // Customize menu appearance and behavior
    SideMenuManager.defaultManager.menuWidth = 280; // Adjust to your preferred width
    SideMenuManager.defaultManager.presentStyle = SideMenuPresentationStyleMenuSlideIn;
    SideMenuManager.defaultManager.menuFadeStatusBar = NO;
    SideMenuManager.defaultManager.menuAnimationBackgroundColor = [[UIColor blackColor] colorWithAlphaComponent:0.3];
    
    // Your other app setup code...
    return YES;
}

Step 2: Initialize the SideMenu Navigation Controller #

Here's where you might have hit a snag: the SideMenuNavigationController doesn't expose the single-argument initWithRootViewController: to Objective-C. Instead, you need to use its designated initializer that includes the menu position (left or right):

// 1. Create your custom menu content view controller
// Replace MenuViewController with your actual menu UI controller
MenuViewController *menuContentVC = [[MenuViewController alloc] init];

// 2. Initialize the SideMenuNavigationController with position
SideMenuNavigationController *leftMenuNav = [[SideMenuNavigationController alloc] initWithRootViewController:menuContentVC menuPosition:SideMenuPositionLeft];

// 3. Assign it to the manager so it's accessible globally
SideMenuManager.defaultManager.leftMenuNavigationController = leftMenuNav;

If you need a right-side menu, just use SideMenuPositionRight and assign to SideMenuManager.defaultManager.rightMenuNavigationController instead.

Step 3: Trigger the Menu From Your Main UI #

To open the menu from a button or gesture in your main view controller, use this code:

// Example: Button action to open left menu
- (IBAction)openLeftMenuTapped:(id)sender {
    [self presentViewController:SideMenuManager.defaultManager.leftMenuNavigationController animated:YES completion:nil];
}

// Optional: Add a swipe gesture to open the menu
- (void)viewDidLoad {
    [super viewDidLoad];
    
    UISwipeGestureRecognizer *leftSwipe = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(openLeftMenuTapped:)];
    leftSwipe.direction = UISwipeGestureRecognizerDirectionRight;
    [self.view addGestureRecognizer:leftSwipe];
}

Quick Note on the Initialization Issue #

The reason you couldn't access initWithRootViewController: is because the Swift-based SideMenu library's SideMenuNavigationController uses a designated initializer that requires a menuPosition parameter. This translates to the two-argument method in Objective-C, which is the only valid way to instantiate it.

Bonus: Customize Menu Behavior #

You can tweak more settings to match your app's needs, like:

• Disallow pushing the same view controller twice: SideMenuManager.defaultManager.allowPushOfSameClassTwice = NO;
• Set a custom animation duration: SideMenuManager.defaultManager.menuAnimationDuration = 0.3;
• Disable menu dismissal when tapping outside: SideMenuManager.defaultManager.dismissOnMenuTap = NO;
