I went farther into the export process, and I'm afraid the process of adding an image as a project file and loading it before the first layout doesn't seem to work on iOS.
At least when exported to Xcode, the simulator will not start the game, while just removing the image and the little code makes it work perfectly.
Any idea how I could make it work on iOS Elliott ? (or someone else)
To be perfectly clear, I'm not using exactly the code you gave me, I'm just loading an image that I added to the project files in C2 (only the path is different so that no internet connection is required, the rest of the code is the same). It works fine on Android and HTML5, but the iOS simulator give me the following error: "Failed to load image: [object Object]"
Then the (HTML5 default) loading bar freezes close to the beginning and the loader layout never starts.
Thanks for your help !
[EDIT] Maybe iOS doesn't like .gif files ... ?
