Wikitude

Hi there,

I have been working on a WIKITUDE-Phonegap app. The application is a location based AR app that shows the markers on the camera view when tilting the phone arounnd (Displaying POI label) The license I have is Educational license so that the app I am developing doesn't have unlicensed watermark on it. 

The problem I am having now is that I want to use my own latitudes & longitudes and description of places instead of the random ones that app generates. I did everything following the Documentation about retrieving the data from JSON file. However, when I built it to the device, the markers won't appear. 

I am developing it on iOS 8.3 - Object-C based and test on iPhone 5.
Anyone has the same problem? How to solve this?

Any answers will be appreciated.
PS. excuse my English if you don't quite get what I tried to explain.

Thank you,
Scott

Hi Scott,

could you please post your JSON file/data and the part where you load it.

Thank you and best regards,
Simon

PS. Your english sounds just fine to me! :-)

Hi Simon,

Thank you for your quick reply :) 

Here is my JSON file format look like.

var myJsonData = ;

Here is fromlocalresource.js code where I call the JSON data

// request POI data
requestDataFromLocal: function requestDataFromLocalFn(lat, lon) {
//var poisNearby = Helper.bringPlacesToUser(myJsonData, lat, lon);
//World.loadPoisFromJsonData(poisNearby);
/*
For demo purpose they are relocated randomly around the user using a 'Helper'-function.
Comment out previous 2 lines and use the following line > instead < to use static values 1:1.
*/
World.loadPoisFromJsonData(myJsonData);
}
};

/*var Helper = {

For demo purpose only, this method takes poi data and a center point (latitude, longitude) to relocate the given places randomly around the user

bringPlacesToUser: function bringPlacesToUserFn(poiData, latitude, longitude) {
for (var i = 0; i < poiData.length; i++) {
poiData.latitude = latitude + (Math.random() / 5 - 0.1);
poiData.longitude = longitude + (Math.random() / 5 - 0.1);
/* 

Note: setting altitude to '0' will cause places being shown below / above user,
depending on the user 's GPS signal altitude.
Using this contant will ignore any altitude information and always show the places on user-level altitude

poiData.altitude = AR.CONST.UNKNOWN_ALTITUDE;
}
return poiData;
}
}
*/

I have completely connected both files in index.html (in the ARChitect World subfolder called "5_ObtainPoiData_2_FromLocalResource")
I hope this is enough for the diagnosis. 

Thank you in advance,
Scott

Hi Simon,

It works! OMG! You have no idea how many weeks I have been trying to fix this. You have just saved my life.

Thank you so much!

Anyway, there are 2 questions I would like to ask 

1.) How can I integrate JSON data into the "Presenting Details" POI and Add the radar? 
2.) can I change the Label to be HTML? I mean I read the documentation but I didn't quite get it. 

Thank you so much for your help.
Cheers,
Scott

when I find the question,I am very happy,because I do same modify as your code.Today, I use the helper function after seeing the answer,but it also doesn't work,I donn't what's wrong with the code.

Hi scott and simon,
I faced same problem as scott that POIs not displayed as per my json file. can you please tell me how you solve that problem? Share your file if possible.
