wikitude 1.2 and JSON Problem
5 CommentsSorted by Oldest First
Hello
OS 6.0.1, iPhone 4, Wikitude 1.2, Xcode 4.5.2
Wikitude 1.2 i not working for me.
I use in the javaScript part of Wikitude JSON (like the SimpleBrowserDemo).
jsonObject = JSON.parse(jsonData);
This part does not seems to work properly for me.
I realized that the JSON part was inside the lib of wikitude1.1 and is not there anymore in wikitude 1.2. Now you can use the -ObjC Flag in other linker flag. I did integrate the SBJSON classes that where in the Simple Browser Demo. But still it seem not to work.
I had a lot of problems because i had an other JSON Framework in my app (problems started with the -ObjC Flag that fixed the error with the linker signaturs in Xcode). Even if i removed it and had only SBJSON from the demo left, the same.
If i switch back to 1.1 it works fine (in this case i use the JSON from the lib and removed all JSON Frameworks and left only the JSON.h to get no errors).
What i do not understand: from where the javaScript gets the JSON Framework in wikitude1.2 if i do:
jsonObject = JSON.parse(jsonData);
?????
Any idea why the JSON does not work for me with wikitude 1.2 ????
Please help.
I tried for hours and days.
I'm a paying user.

Hi Adrian,
Javascripts JSON.parse has nothing to do with the SBJSON framework on iOS. JSON.parse is a built in function from webkits javascript engine. If you have problems parsing the json string, please make sure that the string is a valid json and check if you pass the json as a string or object from objc to javascript. For example: If you have something like this in ObjC '@"newData('%@')"' where %@ will be replaces with your json fromatted ObjC string, then you need JSON.parse to get a json object in javascript. If you replace the ObjC call with '@"newData(%@)"', then you don't need JSON.parse in javascript because you're passing an json object into javascript.
Best regards

Thanks for the answer Andreas.
It's a big help for me that i understand now that the JSON.parse is a built in function from webkits javascript engine.
But if i leave all the javascript the same and switch back to sdk1.1 it works. But on 1.2 and 2.0 the javascript part seems not to work anymore.
I trie to do more debugging now (it's not so easy in the javascript part).
Before the JSON parsing i have the radar stuff. Perhaps i overlooked some changed there (i mena changes from the sdk11 to sdk12).
As soon i know more i will post it here. I You have any other idea why the javascript part stops working from 1.1 to 1.2 please let me know.
Here the javasript start part:
//++++++++Start and generates POIS and Buttons+++++++++++++++++++++++++++
function createOnClickAnimation(imageDrawable) {
var anim = new AR.PropertyAnimation( imageDrawable, 'scaling', 1.0, 1.2, 750, new AR.EasingCurve(AR.CONST.EASING_CURVE_TYPE.EASE_OUT_ELASTIC, {amplitude : 2.0}) );
return anim;
}
function newData(jsonData,tmaxRange) {
console.log("Start");
AR.radar.background = new AR.ImageResource("radar.png");
AR.radar.positionX = 0.02;
AR.radar.positionY = 0.02;
AR.radar.width = 0.15;
AR.radar.centerX = 0.5;
AR.radar.centerY = 0.5;
AR.radar.radius = 0.4;
//AR.radar.northIndicator.image = new AR.ImageResource("radarArrow.png");
//AR.radar.northIndicator.radius = 0.4;
AR.radar.onClick = function(){ AR.logger.info;};
AR.radar.enabled = true;
console.log("Radar Painted");
jsonObject = JSON.parse(jsonData);
console.log("Data loaded");
//document.getElementById("statusElement").innerHTML='Loading JSON objects';
for(var i = 0; i < jsonObject.length; i++)
{
console.log("loop: " + i);
var poidrawables = new Array();
if (jsonObject.name2.length>0) {
var label = new AR.Label(jsonObject.name1,0.5, {offsetY : -1.4,
triggers: {
onClick:
createClickTrigger(i)},
style : {textColor : '#000000',backgroundColor : '#FFFFFF90'}});
var label2 = new AR.Label(jsonObject.name2,0.5, {offsetY : -1.9,
triggers: {
onClick:
createClickTrigger(i)},
style : {textColor : '#000000',backgroundColor : '#FFFFFF90'}});
poidrawables.push(label);
poidrawables.push(label2);
jsonObject.arLabel = label;
jsonObject.arLabel2 = label2;
jsonObject.labelCount = 2;
} else {
var label = new AR.Label(jsonObject.name1,0.5, {offsetY : -1.4,
triggers: {
onClick:
createClickTrigger(i)},
style : {textColor : '#000000',backgroundColor : '#FFFFFF90'}});
poidrawables.push(label);
jsonObject.arLabel = label;
jsonObject.labelCount = 1;
}
var poiImage;
if (jsonObject.type <= maxType) {
poiImage = typeArray;
jsonObject.typeOn =true;
} else {
poiImage = typeArray;
jsonObject.typeOn =true;
}
var img = new AR.ImageDrawable(poiImage, 2.0,
{triggers: {
onClick:
createClickTrigger(i)}}
);
jsonObject.animation = createOnClickAnimation(img);
jsonObject.img = img;
poidrawables.push(img);
geoLoc = new AR.GeoLocation(jsonObject.Point.latitude,jsonObject.Point.longitude,jsonObject.Point.altitude);
var radarCircle = new AR.Circle(0.08, {style: {fillColor: '#468842'}}); //#83ff7b
var radarObject = new AR.GeoObject(geoLoc, {drawables: {cam: poidrawables, radar: radarCircle}});
jsonObject.radarCircle = radarCircle;
jsonObject.poiObj = radarObject;
}
//document.getElementById("statusElement").innerHTML='JSON objects loaded';
document.location = "architectsdk://architectViewReady";
}
Did not find the reason why the javascript part does not work.
The JSON does work and i could log all the values i overgive.
i m puzzled.
No idea why it stoped working with sdk 1.2 and 2.0.
Hi,
have you tried debug your ARchitect World with Safari's web inspector?
