> 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?
