由controllerA推出controllerB

A中：

- (void)viewWillAppear:(BOOL)animated {

    [super viewWillAppear:animated];

    UIView *tabbar = [self.tabBarController.view viewWithTag:1000];

    tabbar.hidden = NO;

    self.tabBarController.tabBar.hidden = YES;

}

- (void)push {

　　BViewController *B = [[BViewController alloc] init];

　　B.hidesBottomBarWhenPushed = YES;

　　[self.navigationController pushViewController:B animated:YES];

}

B.中

- (void)viewWillAppear:(BOOL)animated {

    [super viewWillAppear:animated];

    UIView *tabbar = (UIView *)[self.tabBarController.view viewWithTag:1000];

    tabbar.hidden = YES;

    self.tabBarController.tabBar.hidden = YES;

}
