纯代码开发,window!.rootViewController = UINavigationController(rootViewController: MainController()) 方式跳转,项目崩溃 #84

Description

@tikejc

1、MainController 实现了UITabBarController
class MainController: UITabBarController { }
2、QMUIKit:版本号:4.7.0

3、AppDelegate类里直接跳转到MainController(使用的是UINavigationController方式跳转)
window = UIWindow(frame: UIScreen.main.bounds)
window!.rootViewController = UINavigationController(rootViewController: MainController())
window!.makeKeyAndVisible()

4、项目直接崩溃,出错位置:UINavigationController+QMUI.m 类 203行:
if (!willPushActually) {
QMUIAssert(NO, @"UINavigationController (QMUI)", @"调用了 pushViewController 但实际上没 push 成功,viewController:%@", viewController);
callSuperBlock();
return;
}

这个怎么解决????
