移除navigationController栈中某一个viewC

+ (void)removeController:(UIViewController *)vc {
    NSArray* tempVCA = [vc.navigationController viewControllers];
    for(UIViewController *tempVC in tempVCA)  {
        if([tempVC isKindOfClass:[vc class]]) {
            [tempVC removeFromParentViewController];
        }
    }
}

removeFromParentViewController 这个方法会有一些问题,虽然将控制器移除了,但是返回的依然是这个控制器的导航栏

所以采用,break要加,因为不加可能会有些问题

+ (void)removeController:(UIViewController *)vc {
    NSMutableArray* tempVCA = [NSMutableArray arrayWithArray:[vc.navigationController viewControllers]];
    for(UIViewController *tempVC in tempVCA)  {
        if([tempVC isKindOfClass:[vc class]]) {
            [tempVCA removeObject:tempVC];
            break;
        }
    }
    vc.navigationController.viewControllers = tempVCA;
}
