Description

I'm trying to restore 3000 contacts on a device, since i need to display a progress UI, I had to use something like this (SenchaTouch 2 code but you get the point).

[CODE]

//forEach contacts as contact...

_.delay(function() {
contact.save({callback : function(contact, operation) {
d&&console.log(displayName + ' ~ saved ('+ action +') contact', arguments);
j++;
App.getViewport().mask(

{message: __('restore...'), details: j + '/' + count, progress: j/count, mode: 'determinate'}

);
// Last item ?
if(j == count)

{ contactStore.clearFilter(); return self.afterRestore(callback); }

}});
}, 25*i);

[/CODE]

Works quite well in the simulator but i'm getting regular "failed to return after waiting 10 seconds. main run loop mode: kCFRunLoopDefaultMode" on a device.

Major issue is that UI gets stuck for minutes.

Then i get a few "Received memory warning."

As if somehow the memory stacked somewhere (but the whole point of making separate call was to avoid memory breakdown), so there might be a leak.

At the end, it sometimes work / crash.

Would there be a way to somehow use another thread for theses AddressBook operations?

How could i prevent theses memory leaks?
