ios - UIView 隐藏一次后不显示

Question

我在 ViewController 上有一个名为 scoreView 的 UIView。当我加载 ViewController 时，我将 scoreView 隐藏在 viewDidLoad 方法中。它工作正常。

- (void)viewDidLoad{

[super viewDidLoad];
self.navigationController.navigationBarHidden = YES;
scoreView.hidden = YES;

}

然后在从另一个 View Controller 推送到此 ViewController 之后，我调用了一个方法，我想在其中显示 scoreView。但是 scorView 仍然被隐藏。我哪里做错了？

-(void)levelCompleteViewAppear: (NSString *)score{

NSLog(@"This method is called!");
scoreView.hidden = NO ;
[gameScore setText:score];

}

这就是我从另一个 View Controller 推送到 ViewController 的方式。

-(void)levelComplete{

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];
ViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"ViewController"];
[self.navigationController pushViewController:vc animated:YES];
[vc levelCompleteViewAppear:scoreLabel.text];

}

试试这个，

-(void)viewDidLoad
{
    [super viewDidLoad];
    [self.view addSubview:scrollview];
    [self.view bringSubviewToFront:scrollview];
}
