[bug]:iOS 13 不适配的解决方案

[295060456]

//建议往最高处定义，全局引用

static inline UIWindow * getMainWindow(){
    UIWindow *window = nil;
    if (@available(iOS 13.0, *)) {
        window = [SceneDelegate sharedInstance].window;
    }else{
        window = UIApplication.sharedApplication.delegate.window;
//        [UIApplication sharedApplication].keyWindow
    }return window;
}

同时将- (CYLTabBarController *)cyl_tabBarController 里面进行替换

- (CYLTabBarController *)cyl_tabBarController {
    CYLTabBarController *tabBarController;
    id (^block)(void) = objc_getAssociatedObject(self, @selector(cyl_tabBarController));
    tabBarController = (block ? block() : nil);
    if (tabBarController && [tabBarController isKindOfClass:[CYLTabBarController class]]) {
        return tabBarController;
    }
    if ([self isKindOfClass:[UIViewController class]] && [(UIViewController *)self parentViewController]) {
        tabBarController = [[(UIViewController *)self parentViewController] cyl_tabBarController];
        if ([tabBarController isKindOfClass:[CYLTabBarController class]]) {
            return tabBarController;
        }
    }

    UIViewController *rootViewController = [getMainWindow().rootViewController cyl_getViewControllerInsteadOfNavigationController];;
    if ([rootViewController isKindOfClass:[CYLTabBarController class]]) {
        tabBarController = (CYLTabBarController *)rootViewController;
    }
    return tabBarController;
}

@295060456 多谢指正 , 代码改为下面这几种,是否更为通用?

因为 SceneDelegate 是一个工程里自定义的类名, 可以获取更通用的:

static inline UIWindow *getMainWindow(){
   UIWindow *window = nil;
    window = UIApplication.sharedApplication.delegate.window;
    if (!window) {
        if (@available(iOS 13.0, *)) {
            NSSet<UIScene *> *connectedScenes =  UIApplication.sharedApplication.connectedScenes;
            if (connectedScenes.count > 0 ) {
                UIWindowScene *scene = (UIWindowScene *)connectedScenes.anyObject;
                 window = scene.windows.firstObject;
            }
        }
    }
    return window;
}

或者

static inline UIWindow *getMainWindow(){
   UIWindow *window = nil;
    window = UIApplication.sharedApplication.delegate.window;
    if (!window) {
        if (@available(iOS 13.0, *))
           {
               for (UIWindowScene* wScene in [UIApplication sharedApplication].connectedScenes)
               {
                   if (wScene.activationState == UISceneActivationStateForegroundActive)
                   {
                       window = wScene.windows.firstObject;

                       break;
                   }
               }
           }
    }
    return window;
}

window = UIApplication.sharedApplication.delegate.window; 有时候是拿不到值的，会出问题。我刚好碰上。你直接拉我给你的地址，将会看到效果

ios 13以后 用 SceneDelegate 来管理
