iOS移除SceneDelegate

1.先直接刪除SceneDelegate.h/.m文件

2.在AppDelegate.h添加@property (strong, nonatomic) UIWindow * window;屬性

#import <UIKit/UIKit.h>
@interface AppDelegate : UIResponder <UIApplicationDelegate>
@property (strong, nonatomic) UIWindow * window;
@end
複製代碼

3.移除UIScene代理

移除以前

#import "AppDelegate.h"
@interface AppDelegate ()
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    return YES;
}

#pragma mark - UISceneSession lifecycle
- (UISceneConfiguration *)application:(UIApplication *)application configurationForConnectingSceneSession:(UISceneSession *)connectingSceneSession options:(UISceneConnectionOptions *)options {
    // Called when a new scene session is being created.
    // Use this method to select a configuration to create the new scene with.
    return [[UISceneConfiguration alloc] initWithName:@"Default Configuration" sessionRole:connectingSceneSession.role];
}//移除
- (void)application:(UIApplication *)application didDiscardSceneSessions:(NSSet<UISceneSession *> *)sceneSessions {
    // Called when the user discards a scene session.
    // If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
    // Use this method to release any resources that were specific to the discarded scenes, as they will not return.
}//移除
@end
複製代碼

移除以後

#import "AppDelegate.h"
@interface AppDelegate ()
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    return YES;
}
@end
複製代碼

4.最後在info.plist文件中移除Application Scene Manifest

Swift移除同理

1.先直接刪除SceneDelegate.swift 文件

2.在AppDelegate.swift 中添加 window 屬性 var window: UIWindow?

修改前

@main
class AppDelegate: UIResponder, UIApplicationDelegate {
複製代碼

修改後

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?
複製代碼

3.移除UIScene代理

4.最後在info.plist文件中移除Application Scene Manifest

5.建立本身的Window

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        //設置全局顏色
        UITabBar.appearance().tintColor = UIColor.orange
        
        // 建立Window
        window = UIWindow(frame: UIScreen.main.bounds)
        window?.rootViewController = MainTabViewController();
        window?.makeKeyAndVisible()
        return true
    }
