Question

我在导航项中有一个buttono，其动作是BUTTON_ACTION。通过按下它，MBProgressHUD被激活并且动作有效。但是“dimBackground”使scrren“隐藏”，在导航栏上不起作用，并且可以在MBProgressHUD期间再次按下该按钮。代码是：

  HUD = [[MBProgressHUD alloc] initWithView:self.view];
    [self.view addSubview:HUD];

    // Regiser for HUD callbacks so we can remove it from the window at the right time
    HUD.delegate = self;
    HUD.labelText=@"Buscando Bares...";
    HUD.dimBackground = YES;

    // Show the HUD while the provided method executes in a new thread
    [HUD showWhileExecuting:@selector(BUTTON_ACTION) onTarget:self withObject:nil animated:YES];

我试着用：

HUD = [[MBProgressHUD alloc] initWithView:self.navigationController.view];
        [self.navigationController.view addSubview:HUD];

有什么想法吗？提前谢谢。

Answer 1

要使MBProgressHUD显示在包括UINavigationBar在内的所有UI控件上方，您必须执行以下操作：

 HUD = [[MBProgressHUD alloc] initWithWindow:self.view.window];
 [self.view.window addSubview:HUD];

Answer 2

@ararog是对的，但做起来也很简单

    _progressHUD = [MBProgressHUD showHUDAddedTo:self.view.window animated:YES];

MBProgressHud不适用于导航栏
