Cancel button on BTProgressHUD.Show() does not work. The dialog does not disappear when tap. (Or cannot tap the button.)

• iOS 11.0
• Xamarin.iOS: Version 11.0.0.0
• BTProgressHUD: ver. 1.2.0.5

When doing:

ProgressHUD.Shared.Show("Loading...", -1, ProgressHUD.MaskType.None, 0.75);

I still get this:

and no matter which MaskType I use, it's always the same result.

I just noticed though that if I go away from that tab and come back again (triggering viewDidAppear again) the HUD respects the passed MaskType. (Tried on device with two different MaskTypes to be sure)

So on initial load it's always using a translucent black modal and the second time it's triggered it uses the proper passed MaskType.

Hello, I have a modalVC (form sheet) that calls BTProgressHUD.show(), and it shows up behind the modal. Any idea how to fix this?

Thanks,
Chris

Hey @nicwise , modified a few things and did not submit a pull request. Wanted your opinion on the enhancement. Basically added an extra parameter to ShowContinuousProgress that accepts a UIImage which is then displayed within the ring. Let me know your thoughts.

MakeButton("Show Continuous Progress with Image", () =>
{
       ProgressHUD.Shared.Ring.Color = UIColor.Green;
       ProgressHUD.Shared.ShowContinuousProgress("Continuous progress...", ProgressHUD.MaskType.None, 1000, UIImage.FromBundle("[email protected]"));
       KillAfter(3);
});

I am getting the following exception:
System.MissingMethodException: Method not found: 'Foundation.NSString.StringSize'.

The xamarin version that I am running is the latest that supports Unified API with 64-bit Support for iOS and Mac.

Maybe this is the issue? http://forums.xamarin.com/discussion/29448/alpha-chan-no-longer-building-project-after-switching-to-alpha

Hey, I got an issue with I believe the linker when using OSX Mavericks, but not 100% sure though. At the moment my app won't run in release mode on the device, but will run fine in debug mode when I use BTProgressHUD.
When I comment out the lines that I use BTProgressHUD with the app will run fine in release mode.

Not sure if it was the upgrade to OSX Mavericks, something in BTProgressHUD, the switch to the alpha stream or something odd in iOS 7.0.3.

Have also made an identical thread on Xamarin forums.

Any thoughts or ideas of what I should try next?

In default my progresshud's background color is white.

How can I change it ?

Hello,
Any chance to add support for .net standard 2.0?

I have this issue:
Severity Code Description Project File Line Suppression State
Error NU1202 Package BTProgressHUD 1.2.0.2 is not compatible with netstandard2.0 (.NETStandard,Version=v2.0). Package BTProgressHUD 1.2.0.2 supports:

• monotouch (MonoTouch,Version=v0.0)
• xamarinios10 (Xamarin.iOS,Version=v1.0) app1 1

Can somebody point me to the section where I can set the color of the spinner itself.

I am using v1.2.0.6 on iOS Simulator :iPhone 6, iOS 8.1
The Progress, Success, and Error icon is not showing. Only the continuous icon is showing.
I am called the HUD methods from Xamarin.Forms App, using dependency services.

I want to show the progress image and a Cancel button, but no status message. But the Cancel text overlaps the image. It can easily be reproduced in your BTProgressHUDDemo when you change the status text to null in MainViewController.ViewDidLoad:

        MakeButton("Cancel problem", () =>
            BTProgressHUD.Show("Cancel", () => KillAfter(), null)
            //BTProgressHUD.Show("Cancel", () => KillAfter(), "This is a multilinetext\nSome more text\n more text\n and again more text")
        );

This code brings up a HUD like this:

I am trying to use this in an iOS application. With the following code, the application crashes. The crash is a NullReferenceException in the component.

    public void ShowProgressAlert(string message, Action action)
    {
        InvokeOnMainThread (() => BTProgressHUD.Show(message, -1, ProgressHUD.MaskType.Gradient));
        action ();
        DismissProgressAlert ();
    }

    public void DismissProgressAlert()
    {
        InvokeOnMainThread (() =>
            {
                if (BTProgressHUD.IsVisible)
                    BTProgressHUD.Dismiss ();
            });
    }

This is running on the iOS simulator 'iPhone Retina (4-inch) / iOS 7.1. I am using version 1.10 from the Xamarin Component store.

Hi! I've found an issue. When you use BTProgressHUD togheter with CRSAlertView, it stops showing.

The issue is in ProgressHUD.cs, method void ShowProgressWorker (float progress = -1, string status = null, MaskType maskType = MaskType.None, bool textOnly = false, ToastPosition toastPosition = ToastPosition.Center, string cancelCaption = null, Action cancelCallback = null, double timeoutMs = 1000, bool showContinuousProgress = false, UIImage displayContinuousImage = null)

In this code

            foreach (UIWindow window in windows) {
                    if (window.WindowLevel == UIWindowLevel.Normal && !window.Hidden) {
                        window.AddSubview (OverlayView);
                        break;
                    }
                }

The issue is because CRSAlertView adds a new window, so in addttion to window.WindowLevel == UIWindowLevel.Normal && !window.Hidden, we must check is is IsKeyWindow, eg: I replaced that code with this:

var window = windows.FirstOrDefault(w => w.WindowLevel == UIWindowLevel.Normal && !w.Hidden && w.IsKeyWindow);
                if (window == null)
                {
                    throw new Exception("Can't find a visible key window to add the subview");
                }

                window.AddSubview(OverlayView);

I'm currently using 1.0.0 from NuGet.

I am wondering if there is a way to set the mask when you are not just showing the spinner? i.e showing an Error.

Also I don't seem to be seeing the cross when displaying an error, on iOS 9.2, just a blank space below the text I am using as the status.

Any help would be great, thanks.

Just start the demo app on an iOS 7 device, it will crash at startup.

This is due to #41 which added static fields initialized with Class used in keyboard detection. Some of those have been introduced by iOS8, and as there is no the system version check, it result in fatal exception on iOS 7.

🐛 Bug Report

Attempting to display an iOS UIAlertView whilst a BTProgressHUD is still showing a spinner intermittently causes a crash.

❓ Expected behavior

Dialog to be displayed, with the ability to either dismiss the spinner before or after the UIAlertView is on screen.

🪜 Reproduction steps

Display a progress spinner

BTProgressHUD.Show(message, -1, MaskType.Black);

Display a system dialog

UIAlertView avAlert = new UIAlertView(title, message, null, "OK", null);
avAlert.Show();

Try to dismiss the HUD after the Alert View is present

BTProgressHUD.Dismiss();

This often causes the crash.

🛠 Configuration

I would have said BTProgressHUD directly, however I discovered the 3rd party package ACR.UserDialogs in my installed NuGets, so I've removed that NuGet and it's still crashing.

🤷🏻‍♂️ Workaround:

For some reason forcing a BTProgressHUD.Dismiss prior to display a system alert isn't enough on its own, however, delaying the alert by taking it off and back on the UI thread seems to do the trick 🤔 However, usually I can display a popup whilst the spinner is still going.

        public override void DisplayMessage(string title, string message)
        {
            Device.BeginInvokeOnMainThread(() =>
            {
                Logger.Log(this, $"Display Message '{message}'");
                BTProgressHUD.Dismiss();
                Task.Delay(25).ContinueWith((t) =>
                {
                    Device.BeginInvokeOnMainThread(() =>
                    {
                        UIAlertView avAlert = new UIAlertView(title, message, null, "OK", null);
                        avAlert.Show();
                    });
                });
            });
        }

Alternatively switching from UIAlertView to Xamarin Forms own DisplayAlert works without the hacky delays.

        public override void DisplayMessage(string title, string message)
        {
            Device.BeginInvokeOnMainThread(() =>
            {
                Logger.Log(this, $"Display Message '{message}'");
                PageManager.getMainPage().DisplayAlert(title, message, "OK");
            });
        }

Hi when I show error message on a view which is pushed as popup view then its showing and quickly dispersing. Even though I pass 4000 or any time it just comes and goes.

To open popup view:
await Navigation.PushModalAsync(new PopupPage());

I am using below code to show error message:
BTProgressHUD.ShowErrorWithStatus("please enter text",4000);

However, it works nice on non popup view.

Please suggest

Hi Friends,
its a great library.
i have one issue like when i use BTProgressHUD.show(), it will show me the Progress HUD in Whole navigation controller. so, it disable Whole controller with navigation back button behavior for pop the view controller.

if Progress HUD add in the UIViewController then it solves my issue i think.
is it possible to add BTProgressHUD in UIViewController?

If I call Dismiss() and right after that call Show() again, the HUD does not show up. The problem seems to be the animation that starts in DismissWorker(): if Show() is called before the animation ends, the animation will still complete and thus hide the HUD right after it is shown.

I believe that a fix would be to stop the current animation in Show(), by calling Animate() with the flag UIViewAnimationOptions.BeginFromCurrentState.

🐛 Bug Report

Hello everybody.

Not sure about this bug but I'm going to open this issue just in the case someone else incurs in the same problem. Moreover, as you can read below, may be that the issue is related to Acr.UserDialogs but because of that project is on lockdown, it would help me to know if the compatibility between the twos may be restored.

It looks like that after updating BTProgressHUD from v. 1.3.3. to v. 1.3.4 in a project that also is using Acr.UserDialogs (last version 7.1.0.514 - this project is on lockdown), an exception is thrown when invoking method Acr.UserDialogs.IUserDialogs.ShowLoading(string).

Unfortunately, inspecting the exception does not help: there is no stack trace and the exception message is "Unable to load type."

PLEASE NOTE: I'm still investigating this issue and I will be back in case of new information and tests.

❓ Expected behavior

Calling Acr.UserDialogs.IUserDialogs.ShowLoading(string) should display a waiting dialog.

Reproduction steps

None in particular. This behavior happens always, as far as I call ShowLoading(string).

📦 Package Version: 1.3.4
Reverting BTProgressHUD to v. 1.3.3 solves the issue.

📱 iOS Version: Simulator, v. 14.5

I just got the exception below:

  at BigTed.BTProgressHUD.Show (System.String status, Single progress, MaskType maskType) [0x00000] in <filename unknown>:0 

And it seems to be caused by this line of code, which tries to get the MainScreen instance from a background thread:
https://github.com/nicwise/BTProgressHUD/blob/master/BTProgressHUD/ProgressHUD.cs#L189

Despite it could be easily fixed by wrapping it around an InvokeOnMainThread(), IMHO, ALL the InvokeOnMainThread() should be definitely removed from this component and replaced with just a UIApplication.EnsureUIThread() check... as suggested here: http://tirania.org/monomac/archive/2012/Sep-10.html
it would improve both consistency and efficiency.

When working with gui components, developers are already used to call the InvokeOnMainThread() when they're working in a background thread.
In this way, with a single InvokeOnMainThread() call we can perfom all the gui related operations on all different gui component... eg. show the progressdialog, update a label, populate a combo...

[background thread]
InvokeOnMainThread()
{
   [main thread]
   ProgressHUD.Show();
   TextField.Update();
   Combo.Populate();
   ProgressHUD.Hide();
}
[background thread]

While, delegating the call of the InvokeOnMainThread() to each gui component, would be overkill due to the multiple switches from background thread and main thread...

[background thread]
ProgressHUD.Show();  
    InvokeOnMainThread()
    [main thread]

[background thread]
TextField.Update();
    InvokeOnMainThread()
    [main thread]

[background thread]
Combo.Populate();
    InvokeOnMainThread()
    [main thread]

[background thread]
ProgressHUD.Hide();  
    InvokeOnMainThread()
    [main thread]

[background thread]

Your plugin is nice but it seems that there's no way of changing the Toast Message Font Size in your plugin?

When the Larger Text is enabled in Settings menu, the Text in the Progress ring doesn't scale up or down. Having this feature would add more value to this product.

Hi,

I have noticed with the new iOS 11 the position of the Toasts have now changed to be in the centre and the the hud are now appear slightly off centred. I was wondering is there any plans to re-adjust this back to the way it used to be?

I was wondering is there also a way that you could add the ability to have the hud appear ontop of any window level?

Many Thanks

MaskType.None doesn't allow the user to interact with the underlying elements. This can be seen in the sample app by tapping the Progress button and then attempting to tap one of the Dismiss buttons while the Progress indicator is showing.

Now that the BigTed namespace has been changed to BTProgressHUD, we can no longer do

BTProgressHUD.Show();

Instead, we must use

BTProgressHUD.BTProgressHUD.Show();

Since the whole point of the BTProgressHUD static class was to make it more convenient to display the hud, this feels like a step backwards.

I'm not sure why the namespace was changed, as it breaks compatibility with previous package versions. Assuming there was a good reason, I suggest renaming the BTProgressHUD class to HUD, so we can do:

HUD.Show();

Hi, I just starting using Xamarin.iOS and BTProgressHUD.

I understood while looking at older issues that I couldn't call it in viewDidLoad so I tried to prevent doing that error.

Here's my HomeViewController, look for the NOTE in GetPinsAndShowLoading. Why is this happening?

I'll follow up with a gif of what's happening so you can clearly get what's up.

Also, can't I start fetching stuff from my API in ViewDidLoad so it's faster (not waiting for the view to draw) and show your HUD anyways? I guess I could add a static variable to define wether or not it should display your HUD and play with that maybe?

Thanks for checking this out and keep up the good work!

I have a UIAlertView which asks the user a question. When the clicked event is filed, I Show() a BTProgressHUD. The dialog shows for about a second and then vanishes. I think this has to do with the UIAlertView closing.

        UIAlertView alert = new UIAlertView();
        alert.Title = "Forgot Your Password?";
        alert.AddButton("No");

        alert.Show();

        alert.Clicked += (sender1, ev) => 
        {
            if (ev.ButtonIndex == 1)
            {
                BigTed.BTProgressHUD.Show("Requesting OTP...", maskType: BigTed.BTProgressHUD.MaskType.Gradient);
            } 
        };  

What the title says. I get a System.NullReferenceException when I run the following code: BTProgressHUD.Show(maskType: ProgressHUD.MaskType.Black);

What I tried so far:

• Make sure it is executed on the UI thread.
• Put a breakpoint before it gets called.

I believe that this is happening when the app is launched to do the background fetch and when its done the app crashes.

Configuration

Version: 1.3.3

Platform:

• 📱 iOS
• 🤖 Android

🛠 Configuration

📦 Package Version: 1.3.5

📱 iOS Version: 15.3.1

Wrong orientation in iOS 8 landscape.

In extensions UIApplication.SharedApplication is not available, thus calling some methods results in crashes. SVProgressHUD, on which BTProgressHUD is based, already has defined mechanisms to overcome this issue.

I was profiling my Xamarin From App and I realize that the ProgressHUD takes a lot of memory. Is there any way to avoid this?

Xamarin Froms 3.1.0.5
Device iPad mini 11.4

I'm using BTProgressHUD V 1.12 and seeing an issue on the iPad when using a gradient mask where the mask does not cover the entire view. I only see this issue on iOS 8 and not iOS 7.

I've noticed a similar issue logged with SVProgressHUD and the screen shots on that thread match the behavior I'm experiencing.

https://github.com/TransitApp/SVProgressHUD/issues/342

Screen stolen from above thread:

We are getting isolated crashes in some view controllers. Code wise, nothing has changed in at least two years on these controllers. At this point we are still trying to track down exactly how it is happening.

ProgressHUD.ShowImageWorker (UIKit.UIImage image, System.String status, System.TimeSpan duration)
ProgressHUD+<>c__DisplayClass26_0.b__0 ()
NSActionDispatcher.Apply ()
(wrapper managed-to-native) ObjCRuntime.Messaging.objc_msgSend(intptr,intptr,intptr,intptr,bool)
NSObject.InvokeOnMainThread (System.Action action)
ProgressHUD.ShowImage (UIKit.UIImage image, System.String status, System.Double timeoutMs)
BTProgressHUD.ShowSuccessWithStatus (System.String status, System.Double timeoutMs)
DeleteStoresGridDelegate+<>c__DisplayClass24_0.b__0 ()

UIApplication.Main (System.String[] args, System.IntPtr principal, System.IntPtr delegate)
UIApplication.Main (System.String[] args, System.String principalClassName, System.String delegateClassName)
Application.Main (System.String[] args)

The current version in Xamarin component store of BTProgressHUD is listed as v1.20, whereas version in nuget is v1.0. I assume this is because it is the first release on nuget so it was called 1.0.

Should it be changed and have both versioning the same number as to keep them both in line with each other. I assume the current nuget version is the same as the component store version (did not check, but I guess it could even just add the nuget package for you) but it is hard to tell with versioning numbers what one is currently the most up to date version.

Hi Nic,

first of all thanks for your work about BTProgressHUD, it works almost perfect in my Xamarin.Forms app.

I use your component for displaying a progress dialog when synchronizing data from a remote server.
My problem is, that at the first time I invoke the BTProgressHUD with progress information, the
progress circle will be rendered with wrong colors (iOS). The empty circle is then light grey and it will be filled with white color. After that first call, the progress dialog will be displayed correctly for all further calls (an empty white circle that will be filled with blue color).

I'm using the latest version 1.19 of the BTProgressHUD component under iOS 9.2 with the latest stable version of Xamarin 4. The way I invoke the component is like this (I'm using the Xamarin DependencyService to wrap the BTProgressHUD calls):

public void ShowProgressHUD(string text, float progressValue)
{
  BTProgressHUD.Show(text, progressValue, ProgressHUD.MaskType.Black);
}

public void DismissProgressHUD()
{
  BTProgressHUD.Dismiss();
}

BTProgressHud might crash in DismissWorker:712 when it fails to locate a RootViewController (and yes my app has one of course).
