Crash only in IOs

Crash only in IOs


Hi everyone, in this momment I’m working in a project with cocos creator v1.9.1 but I have a problem with IOs, when I try load a scene the game crash and only show a message “the page was reloaded because a problem occurred several times”


I have an Ipad Air model MD785E/A with IOs version 12.0.1 and I try to run the game in safari. This is a code fragment, when is trying to load the next scene:

var callback = function ()
cc.director.preloadScene(“LevelGame”, function () {
waitingLoadScene = true;
console.log("The scene is load ");
cc.director.loadScene(‘LevelGame’); //change scene
this.scheduleOnce(callback, 3);

Finally when I debug on my Mac the safari’s Ipad it’s close when the page crash and show the message.

PD: I have the same safari’s version in the Mac and in the Ipad.
PD2: That error show only in IOs device.



mmm I did some test for the game, and I think the problem is the device’s memory, because in diferents parts i have more than 1 GB in using. If you look the pictures the “problem” are the “layers”, I don’t understand that so much, but if someone can help me i will be so happy and grateful.


you can use cc.loader.release to release some unused resources,and check the option “auto release” of your scene.


Hi @Big_Bear thanks for the advice, but I already use in this moment, I have two scenes and I’m using in both of them…

1 2

finally I used cc.loader.releaseAll() and the numbers down and I can run the game (thaaaaaanks!!), but the game runs so slow…

Any other advice?


Don’t use cc.loader.releasAll().
loadScene is asynchronous,if you release some resources of the old scene,it will be cause crash.
And cc.loader.releaseAll() will release all dynamic loaded resources,but some resources is loaded for next is also a problem.

I provide a thought for you.
Your can use cc.director.getScene().dependAssets before the callback of loadscene to get all depend resources of old scene,and release them on load scene finished.


var oldAsset = cc.director.getScene().dependAssets;

To attention,this solution is used for the situation that we don’t have any shared resources between the old and next.

If you have some shared assets, your can compare the depend assets between the old and next.get the shared and release


        var oldAsset = cc.director.getScene().dependAssets;
            var newAsset = cc.director.getScene().dependAssets;
            var sharedAsset = ......//to do: get shared assets

Reference:Prevent auto releasing for some specifed assets


Well… I tried to release only no-assets shared but, that doesn’t enough I don’t know what I can do… my problem are the “layers” in web inspector on IOs, and I don’t know what is that?? (the layers).
@Big_Bear thanks for everything!!
