MBProgressHud無法在導航欄上工作

Question

我在導航項中有一個按鈕，其操作是BUTTON_ACTION。按下它，MBProgressHUD被激活並且動作起作用。但是「隱藏」字體的「dimBackground」，在導航欄上不起作用，並且可以在MBProgressHUD中再次按下該按鈕。 的代碼是：

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tryed使用方法：

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

想過這事？提前致謝。

Answer 1

爲了使MBProgressHUD上面包括UINavigationBar的必須這樣做的所有UI控件顯示：

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

Answer 2

@ararog是正確的，但它也簡單，只是做

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