Question

在一个堆栈中，我正在显示MBProgressHUD，如果通过使用另一个堆栈，当一些名为I MBProgressHUD的计算从视图中删除但是它没有从hud中删除..检查我做错了什么..

第一个堆栈名为 LoginViewController.m

- (void)viewWillAppear:(BOOL)animated {
     [super viewWillAppear:animated];

     [MBProgressHUD showHUDAddedTo:self.view animated:YES]; 
}

-(void)myTask {
    // Do something usefull in here instead of sleeping ...

    [MBProgressHUD hideHUDForView:self.view animated:YES];

    [self.hud hide:YES];
    self.hud=nil;
    [self.hud removeFromSuperview];

    //[self.hud showWhileExecuting:@selector(myTask1) onTarget:self withObject:nil animated:YES];
 }

现在ViewController获取电话，但视图将与之前和

相同

经过一些计算，我希望在ViewController中我想通过调用HUD中的方法从视图中删除LoginViewController ..检查代码

 - (void)didReceiveResponseFromServer:(NSString *)responseData
 {
     login=[[LoginViewController alloc]init];

     [self.login myTask];
 }

Answer 1

设置MBProgressHUD

- (void) setupHUD
{
    //setup progress hud
    self.HUD = [[MBProgressHUD alloc] initWithFrame:self.window.bounds];
    [self.SpurView addSubview:self.HUD]; // add it as here.
    self.HUD.dimBackground = YES;
    self.HUD.minSize = CGSizeMake(150.f, 150.f);
    self.HUD.delegate = self;
    self.HUD.labelText = @"Loading...";
}

然后使用隐藏[self.HUD hide:YES];，如代码中所述。

像我一样，我tyr [MBProgressHUD hideHUDForView:bAnimatedView animated:YES] 但是当我快速推进和退出时，它将无法工作。所以我添加一些东西来检查MBProgressHUD的视图。

 MBProgressHUD *HUD = [MBProgressHUD HUDForView:bAnimatedView];
 if (HUD!= nil) {
     [HUD removeFromSuperview];
     HUD=nil;
 }

MBProgressHUD视图没有隐藏
