DemoApp dont react to images

[FredrikHa]

Hi! Thanks for the demo app.

Having some issues to get the app to work correctly. None of the demos work.

Followed all of your steps and no luck... I have installed my trail license inside WikitudePlugin.js Running on my iPhone.

Any suggestions?

Hi !

What do you mean by "none of the demos work" ? Do you have any error message in any of the console ? Can you launch the demos but nothing happens when they're launched ?

Also, on which iOS version is your phone running ?

[FredrikHa]

No error message in the console. Yes, the demos is running and the trail message is showing in front of the camera live preview. But the AR is not showing.

Using iOS 9.3.3

What demo(s) did you launch ? Because most of them requires you to scan a specific picture to actually see AR on the screen (that's the case for at least the first 15 demos). Normally, these required pictures should be shown in a small header bar in the demo, and you can find most of them in a pdf here.

None of them shows some AR right when it starts (except maybe the solar system demo at the bottom of the list, or the geo-based demos).

I have tried to scan the pictures in the pdf. The solar system demo does not work correctly either.

This is my console log in Xcode:

OK. Yeah, I've run into this problem also.

It's not related to Ionicitude, but rather to how Cordova asks for the geolocation permissions in iOS9 (and 8, if I'm not mistaken). As you can see, the message explains that the demo asks for the permission to access the geolocation, but where never given the right to do so. The message also talks about an 'NSLocationWhenInUseUsageDescription' key in your Info.plist.

When confronted with this issue, I followed this thread with one of my test devices and that worked, althought I can't seem to remember if it was an iOS9 or iOS8 device. (Note that after manually adding the keys in your Info.plist, subsequent build of the app will keep these keys, so you won't have to do this all over again.)

Hope that will help !

Whohoo! Thank you!!

Now it works perfekt. <3
