ios - MBProgressHUD 宽限时间和最小时间无法正常工作。如何实现。？

我正在使用 MBProgressHUD用于在执行本地长方法时显示加载，以提供用户良好的体验。一切正常，但现在我必须像这样实现，如果该方法在一秒钟内执行，则不应出现加载。我浏览了 MBProgressHUD 示例，对于这个功能，我发现 setGraceTime 和 setMinShowTime 显示时间，但它们都不能正常工作。因为当我设置宽限时间时，即使方法执行时间超过 1 秒，加载图标也不会出现。这是我的代码

    if (self.HUD == nil)
    {
        self.HUD = [[MBProgressHUD alloc] initWithView:self.view];
        [self.view addSubview:self.HUD];
    }
    self.HUD.labelText = @"lease wait.....";
    //        [self.HUD setMinShowTime:2.0f];

    [self.HUD setGraceTime:1.0f];
    [self.HUD setTaskInProgress:YES];
    [self.HUD show:YES];
    //        [self.HUD hide:YES afterDelay:3];

    [[NSRunLoop currentRunLoop] runUntilDate:[NSDate distantPast]];

    if (mycondition == nil)
    {
            [self myTask:[NSURL fileURLWithPath:strPath]];
            //[self performSelectorselector(mytask withObject:[NSURL fileURLWithPath:strPath]];
    }
    else
    {
      //else
    }

    self.tempView.hidden = YES;
    //        self.HUD.taskInProgress = NO;
    [self.HUD hide:YES];
    self.HUD = nil;

我已经为 this problem's solution 添加了 [[NSRunLoop currentRunLoop] runUntilDate:[NSDate distinctPast]]; 请指导我这段代码有什么问题..？!

您需要在方法执行中从其父 View 中移除 MBProgressHUD 对象。 像这样:

// if the method runs inside one second, the indicator will not be shown

- (void)viewDidLoad
{
  [super viewDidLoad];
  if (HUD == nil)
  {
    HUD = [[MBProgressHUD alloc] initWithView:self.view];
    [self.view addSubview:HUD];
  }
  HUD.labelText = @"lease wait.....";
  [HUD setGraceTime:1.0f];
  [HUD setTaskInProgress:YES];
  [HUD show:YES];
  [self performSelectorselector(runThisMethod) withObject:nil afterDelay:0.9f];
}

- (void)runThisMethod
{
    [HUD removeFromSuperview];
}

// if the method runs after one second, the indicator will be shown for some time until the method runs

- (void)viewDidLoad
{
  [super viewDidLoad];
  if (HUD == nil)
  {
    HUD = [[MBProgressHUD alloc] initWithView:self.view];
    [self.view addSubview:HUD];
  }
  HUD.labelText = @"lease wait.....";
  [HUD setGraceTime:1.0f];
  [HUD setTaskInProgress:YES];
  [HUD show:YES];
  [self performSelectorselector(runThisMethod) withObject:nil afterDelay:1.9f];
}

- (void)runThisMethod
{
    [HUD removeFromSuperview];
}
