BTProgressHUD

If you have an issue, file it here, but also email me - nicw@fastchicken.co.nz - or @fastchicken - as GitHub doesn't notify me! Thanks!.

Port to MonoTouch of the SVProgressHUD.

SVProgressHUD (and BTProgressHUD) is a clean and easy-to-use HUD meant to display the progress of an ongoing task.

This is also available in the Xamarin Component Store.

If you need this for Xamarin.Android, redth has a very similar component

Now includes iOS7-style HUD if the app is running on iOS7

You can force iOS6 or iOS7 style in the IsiOS7 property in ProgressHUD.cs

Installation

  • Grab the .cs files, and the images, and add them to your project.
  • Use it :)

TODO

  • The progress HUD is not Accessability-aware, which would be very good to add. The ObjC code for this is still in the project, just commented out.

Usage

Have a look at the BTProgressHUDDemo project.

There are a few main static methods, however:

BTProgressHUD.Show(); //shows the spinner
BTProgressHUD.Show(status: "Oh hai"); //show spinner + text
BTProgressHUD.ShowSuccessWithStatus("Wow, that worked"); //A big TICK with text
BTProgressHUD.ShowErrorWithStatus("Fail!"); //A big CROSS with text
BTProgressHUD.ShowToast("Hello from Toast"); //show an Android-style toast

All of these can be dismissed with

BTProgressHUD.Dismiss();

BTProgressHUD is aware of the thread you are calling from, and ensures that HUDs are always manipulated from the UI thread.

If you need to make your own instance of the HUD, you can make a new ProgressHUD.

Other Show options

You can call Show with the following parameters

  • status: - show status text
  • progress: - show a progress circle with 0.0 - 1.0 of progress. Call again to change the progress.
  • maskType: - show with the background (the whole window) clear, black or gradient. Default is none, which allows interaction with the underlying elements.
public enum MaskType
{
    None = 1, // allow user interactions, don't dim background UI (default)
    Clear, // disable user interactions, don't dim background UI
    Black, // disable user interactions, dim background UI with 50% translucent black
    Gradient // disable user interactions, dim background UI with translucent radial gradient (a-la-alertView)
}

ShowToast

The toast can be centered or at the top or bottom of the screen. This is controlled by the second parameter.

BTProgressHUD.ShowToast("foo", toastPosition: ProgressHUD.ToastPosition.Center);

ShowSuccess/Error/ShowImage

This method dismisses the activity after 1 second. You can provide your own images if needed - make them 28x28 white PNGs.

BTProgressHUD.ShowSuccessWithStatus("Wow, that worked"); //A big TICK with text
BTProgressHUD.ShowErrorWithStatus("Fail!"); //A big CROSS with text
BTProgressHUD.ShowImage(UIImage.FromFile(…), "Nice one Stu!");

You can use the timeout parameter of ShowImage to control the time before it's dismissed.
