[iOS, MAC] Image not loading from stream or URI binding source

[karthikraja-arumugam]

Description

In image control, if we bind stream or URI image source, it does not load into the view upon initial loading. However, if any layout changes occur, the image loads correctly.

Steps to Reproduce

iOS

1. Run the attached sample in iOS.
2. Note that the image is not displayed in the view
3. Change mobile or simulator orientation, now the image will be visible.

MAC

1. Set the proper local image in ViewModel.

   

2. Run the sample on Mac and repeat the steps, you will get the same result as iOS.

I've checked in the latest version too, still facing the same issue.

@karthikraja-arumugam could you specify what you mean with "latest version"?

I have also came across same problem.

<Image Source="{Binding SVImageSource}"/>

SVImageSource = ImageSource.FromStream(() => response);

As @karthikraja-arumugam showed, image is not visible initially but when screen orientation changes, image shows up.

@jfversluis Is there any suggested workaround on this one?

[crwsolutions]

I have this same behavior, but I think in my case it is caused by the fact that the Source url is answered with a 301 Moved. However I do not know how I can make this image control follow the redirect on iOs like it is doing on android. Help is welcome.

I think in my case it is caused by the fact that the Source url is answered with a 301 Moved.

I solved my problem. I think it was not entirely the same as described. The redirect was from an ip adres to a domain both without ssl. This was solved by adding

<key>NSAppTransportSecurity</key> etc... in the iOs plist. More on this can be found here.

I am facing the same issue for my project. Has someone managed to find a workaround?

[RobK410]

I am getting this error simply by binding a Uri to the Source of an Image in a CollectionView. NSAppTransportSecurity does not help, as this Url is https:// but also, hosted on a valid AWS CDN that returns the image in any browser on/off the device. Works on Android, so it is IOS platform specific issue.
