Google Map crashes in IOS7

Question

We are developing an Hybrid app and we are using google map API in our application. When we are trying to load 2000 data markers in the map, it got crashed. Map is not get crashed in IOS6, IOS5. It is happening only in IOS7. Is there any memory related change done for ios7 application.

Answer 1

As said previously iOS7 is more strict with memory usage. This behavior occurs in other browsers like Chrome, so when an app reach upper limit in memory usage, the crash appears.

I have isolated two test cases using only Gmaps javascript API and jQuery:

Testing with 100 markers: Everything it's ok

Testing with 3000 markers: Crash occurs

http://jsfiddle.net/edfFq/7/embedded/result/

$(document).ready(function () {     var map;     var centerPosition = new google.maps.LatLng(40.747688, -74.004142);       var options = {         zoom: 2,         center: centerPosition,         mapTypeId: google.maps.MapTypeId.ROADMAP     };     map = new google.maps.Map($('#map')[0], options);       for (var i=0;i<2800;i++){               var position = new google.maps.LatLng(40*Math.random(),-74*Math.random());       var marker = new google.maps.Marker({             position: position,             map: map                    });     } }); 

You can get the crash with a less number of markers if your map uses: labels, custom icons and clusters.
