iOS app crashes when imagepicker is closed and upload process is supposed to start

[tsonevn]

Hi @felix-idf ,
thank you for your sample project.

I tested the project on my side, however, I was unable to reproduce this behavior. I also noticed that you are using old versions of nativescript-background-http and nativescript-imagepicker.
Could you update nativescript-background-http to 2.5.1 and nativescript-imagepicker to 2.4.1.
Before rebuilding your app, you should also delete node_modules, platforms, hooks folder. Then run tns run ios.

Let me know, whether the given suggestion helps.

Hi @tsonevn ,
thank you for your response.

I added the latest background-http 2.5.1.
I tried to upgrade the imagepicker-plugin to 2.4.1, but the build fails for iOS. I created a seperate issue here:
https://github.com/NativeScript/nativescript-imagepicker/issues/69

I added the following points that describe my testing environment and maybe they are important and helpful:

• Telerik AppBuilder 3.6.7
• iPhone 4S with iOS 8.4.1

I recorded the whole procedure from opening the imagepicker to start the upload process by selecting one image (which makes the app freezing).

When I select an image and press 'Done', the app freezes and I get the log output, that I mentioned in my first post here.

+[TNSRuntime _getCurrentStack]: unrecognized selector sent to class 0xce9670

I really don't understand why this seems to work for you with my provided sample code. I also tried previous versions of the background-http plugin and also with previous NativeScript versions and the imagepicker plugin.. It never worked on iOS for me.

Hi @felix-idf ,

This problem seems to be related only to nativescritp-imagepicker plugin. I will close this issue and will provide more info about your problem on the other one, which has been logged in nativescritp-imagepicker repo.

Hi @tsonevn ,

you have already closed this issue, but nonetheless I want to say that I can agree.
The problem was just caused by the way I am getting the image from the picker.
Probably, my code was based on an older sample code of the image-picker and background-http plugin.
The upload works fine now for Android and iOS using imagepicker 2.4.0 and the latest background-http plugin (2.5.1). I Still have some trouble building the app with the latest imagepicker plugin, but that seems to be related to the AppBuilder, so it is another topic.

Thanks again.

Hi @felix-idf,
In my further research, I found that this behavior could be related due to a problem with installation one of the plugin's dependencies.
nativescript-imagepicker plugin uses nativescirpt-telerik-ui and its RadListView component to display the images from the gallery.

While adding nativescript-imagepicker version 2.5.1, nativescirpt-telerik-ui has not been installed properly, which could cause this issue.

To fix this, you could add nativescript-imagepicker manually with appbuilder plugin add nativescript-telerik-ui to add again the latest available version of nativescript-imagepicker version 2.5.1. then try to rebuild the app.

package.json

{
  "dependencies": {
    "nativescript-imagepicker": "2.5.1",
    "nativescript-telerik-ui": "1.6.1",
    "tns-core-modules": "2.5.0"
  },
  "devDependencies": {}
}

Hope this helps.
