When opening a map view with multiple annotations rapidly clicking between them crashes the application. This was introduced in 2.12 version of ti.map and still and issue with 3.0.0. I have tested version 2.11 of ti.map and have been unable to recreate the issue. Steps to reproduce: Create a window with a button, on button click open a window in a navigation flow with a map Populate the map with pins/annotations Select annotations and deselect them by clicking on map. the application will crash on the 4 or 5 click.


  1. Hans Knöchel 2017-10-16 Hey there! Was it 2.12.0 or 2.12.1 / 2.12.2? If it was 2.12.0, the ticket causing it was TIMOB-24375, which is kind of unrelated. If it was MOD-2357, it would make more sense. We'll try to create a test-case for you if you are not able to provide one. *EDIT*: Reproducible with this test-case:
       var Map = require('ti.map');
       var win = Titanium.UI.createWindow();
       var ann = [];
       for (var i = 0; i < 10; i++) {
           title: 'Title',
           subtitle: 'subtitle',
           latitude: Math.random() * 10 + 40,
           longitude: Math.random() * 10,
       var mapview = Map.createView({
         annotations: ann
    *EDIT 2*: It's definitely 2.12.2 and [this commit](https://github.com/appcelerator-modules/ti.map/commit/e64d01021bf81078ca92df165426aeef28125487). Not sure how to fix the race-condition so far, so this might need more time for investigation.
  2. Hans Knöchel 2017-10-16 Hey there, would you mind to test [this build](https://www.dropbox.com/s/br7cgoh3xqe7tmc/ti.map-iphone-2.12.3.zip?dl=0) (2.1.3) and try to reproduce it? I was not anymore but would like to await your feedback before setting up the PR. Thanks!
  3. Hans Knöchel 2017-10-17 Fixed in Ti.Map [2.12.3](https://github.com/appcelerator-modules/ti.map/releases/tag/ios-2.12.3) and [3.0.1](https://github.com/appcelerator-modules/ti.map/releases/tag/ios-3.0.1).
