In my sencha-tpuch / phonegap app on iOS I want my app not to change orientation with the device its used on. how could I suppress orientation change in sencha-touch or what would I override exactly? thnx!
You dont need to edit any code. All you need to do is go to your configuration files and specify orientations you want to support. By default all 4 orientations are supported, you have to edit it to support orientations you want. Rebuild the application and Go.
The entry should be in one of the following files:
phonegap.plist/application.plist/config.xml
Also check this link.
With only Sencha Touch, as it cannot force browser not to change orientation, it is NOT possible to remove orientation change. See this link.
