v 1.3.1 Crash - Xamarin - Targeting 13.2 IOS

[mattcuda]

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)

Same problem .

Hi Guys, think this is a problem with images not being included. Whenever i called ShowSuccessWithStatus i would get a null ref exception, this was due to the SuccessImage being null.

I downloaded the library and moved the images to my own resources folder and it fixed the problem for me.

The strange part was when i added the BTProgressHud folder to my project the images still had a build action of BundleResources but still caused the null ref exception. They did not load in correctly until i added them to my own Resources folder.

Think this is related

#76

@tony98789 looks like you are right. Tested #76 though and it doesn't seem to solve the issue. Will investigate this further.

@Redth do you have any idea, why BundleResources don't make it into the DLL?

[Redth]

I think they may only get included if it’s a binding project. You might have to add a .targets file to the nuget package and include the assets directly in the nupkg and add the <ItemGroup><BundleResource Include=“$(MSBuildThisFileDirectory)\assets\image.png” /></ItemGroup> (or similar - that’s a from memory typed on phone code snippet).

@Redth I've just been working a bit on this. I managed to get the images and .targets file added to the NuGet package and the images seem to get included in the built IPA file when referencing the produced NuGet.

However, it still doesn't seem to pick up the images when trying to load them from bundle. I see the images on the simulator file system.

I added a file called BTProgressHud.targets to the NuGet with following contents (My branch here):

<Project>
    <ItemGroup>
        <BundleResource Include="$(MSBuildThisFileDirectory)\BTProgressHud\error_7.png" />
        <BundleResource Include="$(MSBuildThisFileDirectory)\BTProgressHud\error_7@2x.png" />
        <BundleResource Include="$(MSBuildThisFileDirectory)\BTProgressHud\error.png" />
        <BundleResource Include="$(MSBuildThisFileDirectory)\BTProgressHud\error@2x.png" />
        <BundleResource Include="$(MSBuildThisFileDirectory)\BTProgressHud\success_7.png" />
        <BundleResource Include="$(MSBuildThisFileDirectory)\BTProgressHud\success_7@2x.png" />
        <BundleResource Include="$(MSBuildThisFileDirectory)\BTProgressHud\success.png" />
        <BundleResource Include="$(MSBuildThisFileDirectory)\BTProgressHud\success@2x.png" />
    </ItemGroup>
</Project>

I don't really see what else should be needed for this to work?

Here is a screenshot of the package contents exploring with NuGet Package Explorer. I've also attached a NuGet package (just rename to .nupkg)
