How can we help you today?
Not able to run 01_ImageTracking_1_ImageOnTarget using cordova Plugin
Wikitude Support
Hi,
Can you please describe your issue in more details - it sounds like you're testing the client based Image Recognition feature and have issues with it. Does this issue occur in the sample app? If so, do you get any error log output? Does it occur on Android and iOS or just one platform?
Thx and greetings
Nicola
hi,
Yes I am testing Client based image Recognition feature and it is from the sample app. It occurs in iOS. I don't have any logs for this. index.html page opens up but not the camera. Is there any specific settings I need to do in the app.
Wikitude Support
Hi,
So this behaviour occurs with the unchanged sample app and you followed the setup guide in the documentation? Did you make sure that all permissions are set and the lifecycle handling is correct?
Thx and greetings
Nicola
Below are the permission I have added in infoplist. Camaera is opening fine when I integrate with all the features.
{
"NSAppTransportSecurity" :
{
"NSAllowsArbitraryLoads" : true
} ,

app.initialize();

Hello,
I think the best thing to get to the bottom of this issue would be for you to check the JavaScript console for any errors, I suspect there will be something.
To do that on an iOS device you need to use Safari. While you device is running the app and is connected to your Mac, go to Developer > YOUR_DEVICE > index.html. Click the reload button and see whether any errors pop up.
