{

Class clazz =NULL;

if([viewControllerclass] == viewController) {

clazz = viewController;

}elseif([viewControllerisKindOfClass:[NSStringclass]]){

clazz =NSClassFromString(viewController);

}

UIViewController*vc =nil;

if(clazz) {

vc = [[clazzalloc]init];

}else{

vc = viewController;

}

//push时影响下级页面tabbar的显示

self.hidesBottomBarWhenPushed=YES;

[self.navigationControllerpushViewController:vcanimated:YES];

//pop时影响自己的页面的tabbar显示；

if(self.navigationController.viewControllers.count==2) {

self.hidesBottomBarWhenPushed=NO;

}

}
