如何使用Objective c在iOS中单击通知时打开视图控制器？

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    // 解析通知内容，根据需要处理
    // NSDictionary *notificationData = userInfo[@"data"];

    // 获取应用的主窗口
    UIWindow *mainWindow = [UIApplication sharedApplication].keyWindow;

    // 获取根视图控制器
    UIViewController *rootViewController = mainWindow.rootViewController;

    // 遍历视图控制器层次结构，找到目标视图控制器
    UIViewController *targetViewController = [self findTargetViewController:rootViewController];

    // 推入导航堆栈或以模态方式显示目标视图控制器
    if (targetViewController) {
        // 如果目标视图控制器在导航控制器中
        if ([targetViewController.navigationController isKindOfClass:[UINavigationController class]]) {
            UINavigationController *navigationController = (UINavigationController *)targetViewController.navigationController;
            [navigationController pushViewController:targetViewController animated:YES];
        } else {
            // 以模态方式显示目标视图控制器
            [rootViewController presentViewController:targetViewController animated:YES completion:nil];
        }
    }
}

- (UIViewController *)findTargetViewController:(UIViewController *)viewController {
    // 根据你的应用结构，遍历视图控制器层次结构，找到目标视图控制器
    // 示例代码中使用了递归方式遍历，你也可以使用其他方式来实现

    // 示例代码中假设目标视图控制器是一个名为TargetViewController的类
    if ([viewController isKindOfClass:[TargetViewController class]]) {
        return viewController;
    }

    for (UIViewController *childViewController in viewController.childViewControllers) {
        UIViewController *targetViewController = [self findTargetViewController:childViewController];
        if (targetViewController) {
            return targetViewController;
        }
    }

    return nil;
}
