Hi everyone!
I had a problem of downloading of more than 1000 files.
I've fixed it in cordova.js file. There wasn't deleted an iframe, which had
been created for calling a command on ObjectiveC part. That is why after
calling a command for 1000+ times there appeared 1000+ iframes and there was no
memory to create more.
So there is needed to add only 2 lines of code for fixing it:
function onIframeUnload() {
document.body.removeChild(execIframe);/*line #1*/
delete execIframe;/*line #2*/
execIframe = null;
setTimeout(pokeNativeViaIframe, 0);
}
