Becky Gibson commented on CB-828:
---------------------------------
regarding ARC, I'm working on it here:
https://github.com/becka11y/incubator-cordova-ios/tree/ARC
As of 6/21 does compile and app loads but does not run. I'll slowly poke away
at debugging and cleanup. I haven't looked at any of the blocks, yet, nor
cleaned up passing of NSError references.
> iOS contact.save() stucks the UI from updating on heavy load & has memory
> leaks.

> Key: CB-828
> URL: https://issues.apache.org/jira/browse/CB-828
> Project: Apache Cordova
> Issue Type: Bug
> Components: iOS
> Reporter: Olivier Louvignes

> Labels: contacts
> Fix For: 1.9.0

>
> 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?
