Question

I am stuck on a blank white screen while loading Trigger.io iOS with Sencha 2.

It works fine on Android, but on iOS, it just shows a blank white screen.

Here’s the debug output:

[INFO] 943E7E1BD31/Library/Application%20Support/Forge/assets-AA20D894-4614-43FB-BE67-D78F05175E9B/src/index.html

[DEBUG]     };
[DEBUG] }

[DEBUG]     params =     {
[DEBUG]     };
[DEBUG] }
[DEBUG] Returning to

[DEBUG]     content = \"<null>\";
[DEBUG]     status = success;
[DEBUG] }

After hiding launch image, it’s calling content = \"<null>\"; ?

Answer 1

It turns out Sencha 2 has a bug, it was throwing an error like this:

Error: [ERROR][Ext.viewport.Ios#undefined] Timeout waiting for window.innerHeight to change

I did some research, and it seems to be a bug relating to Safari vs. UI Web View.

To solve this problem, add this under Ext.application({

viewport: { autoMaximize: false },
