Webview Swipe issue - Appcelerator Titanium - appcelerator-mobile

Question

Right now I am using one webview to show data from my aplicationDatadirectory, here everything is working fine, I get content when user click next back respectively. Now what I am doing is in onload of webview I register "touchevent" and "touchmove" in webview's html like this :-
$.webview.evalJS('document.getElementsByTagName("body")[0].addEventListener("touchstart", function mytouch(){Ti.App.fireEvent("touch", {X:event.touches[0].pageX,Y:event.touches[0].pageY,length:event.touches.length});}, false);');
$.webview.evalJS('document.getElementsByTagName("body")[0].addEventListener("touchmove", function mymove(){Ti.App.fireEvent("move", {X:event.touches[0].pageX,Y:event.touches[0].pageY,length:event.touches.length});}, false);');
on the basis of this I find swipe event. I get correct html in webview(I can see images). But I am unable to get touchstart and move call. I dont know what is the problem here. I set data in webview using url here.
Now when I set data in webview using html(I used data of my html file(given below) in one var) now I am unable to see images it just shows me one black border(empty) but here my touchstart and touchmove events are firing also my swipe is also working as expected. I am checking this functionality in iPhone.
Can any one find the issue what is going wrong here? Thanks.

I think that this depends on the time when you apply
$.webview.evalJS('document.getElementsByTagName("body")[0].addEventListener("touchstart", function mytouch(){Ti.App.fireEvent("touch", {X:event.touches[0].pageX,Y:event.touches[0].pageY,length:event.touches.length});}, false);');
$.webview.evalJS('document.getElementsByTagName("body")[0].addEventListener("touchmove", function mymove(){Ti.App.fireEvent("move", {X:event.touches[0].pageX,Y:event.touches[0].pageY,length:event.touches.length});}, false);');
If you use the html property data is loaded immediately and you can use the code exactly after setting html content. If you use the url (even if it is located locally, which might be difficult for android) then you need to wait a short time until the page is loaded. There is also an event listener for that (web view-event load) but i can't say if that works for local resources but i don't think so.
In this case you should apply your javascript snippet into your html resources (if they are locally) instead of manually adding it using evalJS.
Please note that there is an issue on android that you can't use local images (resources folder) in your webview when you provide the content via html property.

I made it swipe working in iOS(in android it was working).
I did not expect this thing to be a reason but I do not know logic behind it. I was accessing .xhtml files from application data directory and it was working without any issue in android but in iOS it was not.
I just change(rename in my code) .xhtml file to .html and now it is working. :)
Hope this can help someone who is looking for the same.(or just for his interest)
Thanks.
